Platform: iOS
SDK major version: v6
Language: English (en)
Translation: AI-translated from Korean. Original: https://docs.buzzvil.com/docs/buzzbenefit-ios/v6/migration

This guide covers updates within Buzzvil iOS SDK v6 and migration from v5 to v6.

## Update within v6

The integration guides are based on the latest release. Before updating the SDK, check the requirements below and the [iOS release notes](https://docs.buzzvil.com/en/docs/release-notes/ios/release-notes).

### Update to 6.9.0 or later

Starting with Buzzvil SDK 6.9.0, the minimum supported iOS version and Xcode version changed.

| SDK version    | Minimum supported iOS | Xcode         |
| -------------- | --------------------- | ------------- |
| 6.9.0 or later | iOS 15.0              | 26.0 or later |
| 6.8.x          | iOS 13.0              | 16.0 or later |

- To use the latest SDK, set your app's deployment target to iOS 15.0 or later.
- If you need to retain support for iOS 13 or iOS 14, use a 6.8.x version.

> ✏️  **Note**\
> iOS 13 technical support ended on January 1, 2026. See [End of iOS 13 support](https://docs.buzzvil.com/en/docs/policy/announcement/sdk-versioning-eol-update-announce#2025%EB%85%84-12%EC%9B%94-5%EC%9D%BC-%EA%B3%B5%EC%A7%80) for details.

### End of CocoaPods distribution

CocoaPods distribution of Buzzvil SDK ends with 6.10.x. Because the CocoaPods repository (trunk) becomes read-only on December 2, 2026, versions released after that will be provided only through Swift Package Manager.

- Versions that have already been released can still be installed with CocoaPods.
- To receive later updates, switch to Swift Package Manager. See [Install with Swift Package Manager](https://docs.buzzvil.com/en/docs/buzzbenefit-ios/v6/getting-started#swift-package-manager) for instructions.

## Migrate from v5 to v6

This guide describes the configuration required when migrating from Buzzvil iOS SDK v5 to the latest v6.

See the [GitHub sample code](https://github.com/Buzzvil/buzz-sdk-samples/tree/master/buzzvil-sdk-v6-ios) for examples of actual implementations.

> ✏️  **Note**\
> This guide is based on the latest v5 and v6 releases.

> ❗️ **Caution**\
> **Buzzvil SDK 6.x** requires **configuration on Buzzvil's server to work correctly**. When migrating from an earlier version, contact your Buzzvil account manager or the team at <partnership@buzzvil.com>.

> ✅  **Important**\
> The contract structure changed starting with Buzzvil SDK 5.x. If you migrate from BuzzAd SDK 3.x or BuzzScreen SDK 4.x to Buzzvil SDK 6.x, contact your Buzzvil account manager or <partnership@buzzvil.com> about renewing your contract.

## Getting started

### Requirements

1. Review the updated requirements for Buzzvil SDK v6 below and apply them to your project settings.

#### Requirements

- deployment target
  - **Minimum supported**: iOS 15.0 or later
- Xcode 26.0 or later

### Obtain integration IDs

**Feed (BenefitHub)** has become **web-based BenefitHub**. The Feed Unit ID is no longer used directly in integration code.

You can continue using your existing App ID, Native Unit ID, and Interstitial Unit ID.

### Integrate a reward server

With the addition of Lucky Box and Mission Pack, you must handle the request parameters described in the [postback integration guide](https://buzzvil.atlassian.net/wiki/spaces/BDG/pages/1756004654/API#HTTP-Request-Parameters).

### Install the SDK

### Swift Package Manager

Follow these steps to import the Swift package.

> ✏️  **Note**\
> If you are migrating from a CocoaPods-based project, run pod deintegrate to remove CocoaPods from your Xcode project. You can safely delete the .xcworkspace file generated by CocoaPods afterward.

1. In Xcode, go to `File > Add Package Dependencies`.

2. Search for the Buzzvil SDK Swift Package GitHub repository.

```
https://github.com/Buzzvil/buzzvil-ios-sdk
```

3. Select a version. We recommend Up to Next Minor Version.

4. Select `BuzzvilSDK` from the package products.

> ✏️  **Note**\
> If you do not use BuzzBanner, you can select `BuzzvilSDK-WithoutThirdParty`. This limits BuzzBanner and interstitial ad features within BenefitHub.

For details about adding package dependencies, see the [official Apple Developer documentation](https://developer.apple.com/documentation/xcode/adding-package-dependencies-to-your-app).

### Cocoapods

> ❗️ **Caution**\
> CocoaPods distribution of Buzzvil SDK ends with 6.10.x. Because the CocoaPods repository (trunk) becomes read-only on December 2, 2026, versions released after that will be provided only through Swift Package Manager. Use Swift Package Manager for new integrations. See [End of CocoaPods distribution](https://docs.buzzvil.com/en/docs/buzzbenefit-ios/v6/migration#cocoapods-%EB%B0%B0%ED%8F%AC-%EC%A2%85%EB%A3%8C) for details.

To install the Buzzvil SDK using CocoaPods, add BuzzvilSDK to your `Podfile`.

> ✏️  **Note**\
> The code snippet below is based on the last version available through CocoaPods (6.10.x).

```
   pod 'BuzzvilSDK', '~> 6.10'
```

Reference — Previous code (BuzzAdBenefit SDK v5)

```actionscript3
pod 'BuzzAdBenefit', '= 5.31.3'
```

## Initialize the SDK

### Initialize BuzzvilSDK

The constructor parameter of `BuzzBenefitConfig.Builder` has been renamed from `appID` to `appId`.

**Swift**

```swift
import BuzzvilSDK

let config = BuzzBenefitConfig.Builder(appId: "YOUR_APP_ID")
    .build()
BuzzBenefit.shared.initialize(with: config)
```

**Objective C**

```objectivec
@import BuzzvilSDK;

BuzzBenefitConfig *config = [BuzzBenefitConfig configWith:^(BuzzBenefitConfigBuilder * _Nonnull builder) {
  builder.appId = @"YOUR_APP_ID";
}];
[[BuzzBenefit sharedInstance] initializeWith:config];
```

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
import BuzzvilSDK

let config = BuzzBenefitConfig.Builder(appID: "YOUR_APP_ID")
    .build()
BuzzBenefit.shared.initialize(with: config)
```

**Objective C**

```objectivec
@import BuzzvilSDK;

BuzzBenefitConfig *config = [BuzzBenefitConfig configWithBlock:^(BuzzBenefitConfigBuilder * _Nonnull builder) {
  builder.appID = @"YOUR_APP_ID";
}];
[[BuzzBenefit sharedInstance] initializeWithConfig:config];

```

#### Configure dark mode

Dark mode is now configured through server settings rather than code. Remove the previous dark-mode-related code.

| Dark mode option                      | Description                                                                        |
| ------------------------------------- | ---------------------------------------------------------------------------------- |
| `BuzzBenefitUserInterfaceStyleLight`  | Uses light mode regardless of the system's dark mode setting.                      |
| `BuzzBenefitUserInterfaceStyleDark`   | Uses dark mode regardless of the system's dark mode setting.                       |
| `BuzzBenefitUserInterfaceStyleSystem` | The SDK's default dark mode setting (`기본 값`). Uses the system's dark mode setting. |

Remove the functions previously used to configure dark mode.

**Swift**

```swift
import BuzzvilSDK

@main
final class AppDelegate: UIResponder, UIApplicationDelegate {
  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
    // ...생략...
    BuzzBenefit.shared.setUserInterfaceStyle(.system) // 삭제 처리
    return true
  }
}
```

**Objective C**

```objectivec
@import BuzzvilSDK;

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // ...생략...
  [[BuzzBenefit sharedInstance] setUserInterfaceStyle:BuzzBenefitUserInterfaceStyleSystem]; // 삭제 처리
  return YES;
}

@end
```

### Log in

No changes.

## BenefitHub

### Integration

#### Initialize BenefitHub

Registration with `BuzzBenefitConfig` using `BZVFeedConfig` has been removed. The `setDefaultFeedConfig` function in `BuzzBenefitConfig` has also been removed, so remove the related code.

**Swift**

```swift
import BuzzvilSDK

@main
class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {
        let config = BuzzBenefitConfig.Builder(appId: "YOUR_APP_ID")
          .build()
        BuzzBenefit.shared.initialize(with: config)
        return true
    }
}
```

**Objective-C**

```objectivec
@import BuzzvilSDK;

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    BuzzBenefitConfig *config = [BuzzBenefitConfig configWith:^(BuzzBenefitConfigBuilder * _Nonnull builder) {
      builder.appId = @"YOUR_APP_ID";
    }];
    [BuzzBenefit sharedInstance] initializeWithConfig:config]; 
    return YES;
}

@end
```

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
import BuzzvilSDK

@main
class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {
        let feedConfig = BZVFeedConfig { builder in
            builder.unitID = "YOUR_FEED_UNIT_ID"
        }
        let config = BuzzBenefitConfig.Builder("YOUR_APP_ID")
            .setDefaultFeedConfig(feedConfig)
            .build()
        BuzzBenefit.shared.initialize(with: config)
        return true
    }
}
```

**Objective-C**

```objectivec
@import BuzzvilSDK;

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    BZVFeedConfig *feedConfig = [BZVFeedConfig configWithBlock:^(BZVFeedConfigBuilder * _Nonnull builder) {
        builder.unitID = @"YOUR_FEED_UNIT_ID";
    }];
    BuzzBenefitConfig *config = [BuzzBenefitConfig configWithBlock:^(BuzzBenefitConfigBuilder * _Nonnull builder) {
        builder.appID = @"YOUR_APP_ID";
        builder.defaultFeedConfig = feedConfig;
    }];
    [BuzzBenefit sharedInstance] initializeWithConfig:config]; 
    return YES;
}

@end
```

#### Display BenefitHub

The previous `BZVBuzzAdFeed` object has been renamed `BuzzBenefitHub`. Use the renamed object to display BenefitHub.

Retrieving the ViewController and using it as a child view controller is still supported.

**Swift**

```swift
let yourViewController = UIViewController()
let benefitHub = BuzzBenefitHub()
benefitHub.show(on: yourViewController)
```

**Objective C**

```objectivec
UIViewController *yourViewController = [[UIViewController alloc] init];
BuzzBenefitHub *benefitHub = [[BuzzBenefitHub alloc] init];
[benefitHub showOn:yourViewController];
```

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
/** 참고 - 변경 전 코드(BuzzAdBenefit v5) **/

let yourViewController = UIViewController()
let buzzAdFeed = BZVBuzzAdFeed { _ in }
buzzAdFeed.show(on: yourViewController)
```

**Objective-C**

```objectivec
/** 참고 - 변경 전 코드(BuzzAdBenefit v5) **/
UIViewController *yourViewController = [[UIViewController alloc] init];
BZVBuzzAdFeed *buzzAdFeed = [BZVBuzzAdFeed feedWithBlock:^(BZVBuzzAdFeedBuilder * _Nonnull builder) {}];
[buzzAdFeed showOn:yourViewController];
```

#### Display BenefitHub with a non-default configuration

Displaying BenefitHub with a non-default configuration has been removed. Declare a `BuzzBenefitHub` object to display BenefitHub. Remove the associated `BZVFeedConfig` code.

#### Lucky Box

You can now open Lucky Box directly through the BenefitHub object. The code for [opening Lucky Box directly](https://docs.buzzvil.com/en/docs/buzzbenefit-ios/v5/feed#%EB%9F%AD%ED%82%A4%EB%B0%95%EC%8A%A4%EB%A5%BC-%EB%B0%94%EB%A1%9C-%ED%91%9C%EC%8B%9C%ED%95%98%EA%B8%B0) has changed.

**Swift**

```swift
let yourViewController = UIViewController()
let benefitHub = BuzzBenefitHub()
let benefitHubConfig = BuzzBenefitHubConfig.Builder()
  .setQueryParams(BuzzBenefitHubPage.luckyBox.toRedirectQueryParams())
  .build()
benefitHub.setConfig(benefitHubConfig)
benefitHub.show(on: yourViewController)
```

**Objective C**

```objectivec
UIViewController *yourViewController = [[UIViewController alloc] init];
BuzzBenefitHubConfig * benefithubConfig = [BuzzBenefitHubConfig configWith:^(BuzzBenefitHubConfigBuilder * _Nonnull builder) {
  builder.queryParams = [BuzzBenefitHubPage.luckyBox toRedirectQueryParams];
}];

[self.benefitHub setConfig:benefithubConfig];
[benefitHub showOn:yourViewController];
```

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
/** 참고 - 변경 전 코드(BuzzAdBenefit v5) **/
let yourViewController = UIViewController()
let feedConfig = BZVFeedConfig { builder in
  builder.unitID = "BENEFIT_HUB_UNIT_ID"
  builder.initialNavigationPage = .luckyBox
}
let buzzAdFeed = BZVBuzzAdFeed(block: { builder in
  builder.config = feedConfig
})
```

**Objective-C**

```objectivec
/** 참고 - 변경 전 코드(BuzzAdBenefit v5) **/
UIViewController *yourViewController = [[UIViewController alloc] init];
BZVFeedConfig *feedConfig = [BZVFeedConfig configWithBlock:^(BZVFeedConfigBuilder * _Nonnull builder) {
  builder.unitID = @"BENEFITHUB_UNIT_ID";
  builder.initialNavigationPage = BZVFeedInitialNavigationPageLuckyBox;
}];

BZVBuzzAdFeed *buzzAdFeed = [BZVBuzzAdFeed feedWithBlock:^(BZVBuzzAdFeedBuilder * _Nonnull builder) {
  builder.config = feedConfig;
}];
[buzzAdFeed showOn:yourViewController];
```

#### Mission Pack

You can now open Mission Pack directly through the BenefitHub object. The code for [opening Mission Pack directly](https://docs.buzzvil.com/en/docs/buzzbenefit-ios/v5/feed#%EB%AF%B8%EC%85%98%ED%8C%A9%EC%9D%84-%EB%B0%94%EB%A1%9C-%ED%91%9C%EC%8B%9C%ED%95%98%EA%B8%B0) has changed.

**Swift**

```swift
let yourViewController = UIViewController()
let benefitHub = BuzzBenefitHub()
let benefitHubConfig = BuzzBenefitHubConfig.Builder()
  .setQueryParams(BuzzBenefitHubPage.missionPack.toRedirectQueryParams())
  .build()
benefitHub.setConfig(benefitHubConfig)
benefitHub.show(on: yourViewController)
```

**Objective C**

```objectivec
UIViewController *yourViewController = [[UIViewController alloc] init];
BuzzBenefitHubConfig * benefithubConfig = [BuzzBenefitHubConfig configWith:^(BuzzBenefitHubConfigBuilder * _Nonnull builder) {
  builder.queryParams = [BuzzBenefitHubPage.missionPack toRedirectQueryParams];
}];

[self.benefitHub setConfig:benefithubConfig];
[benefitHub showOn:yourViewController];
```

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
/** 참고 - 변경 전 코드(BuzzAdBenefit v5) **/
let yourViewController = UIViewController()
let feedConfig = BZVFeedConfig { builder in
  builder.unitID = "BENEFIT_HUB_UNIT_ID"
  builder.initialNavigationPage = .missionPack
}
let buzzAdFeed = BZVBuzzAdFeed(block: { builder in
  builder.config = feedConfig
})
```

**Objective-C**

```objectivec
/** 참고 - 변경 전 코드(BuzzAdBenefit v5) **/
UIViewController *yourViewController = [[UIViewController alloc] init];
BZVFeedConfig *feedConfig = [BZVFeedConfig configWithBlock:^(BZVFeedConfigBuilder * _Nonnull builder) {
  builder.unitID = @"BENEFITHUB_UNIT_ID";
  builder.initialNavigationPage = BZVFeedInitialNavigationPageMissionPack;
}];

BZVBuzzAdFeed *buzzAdFeed = [BZVBuzzAdFeed feedWithBlock:^(BZVBuzzAdFeedBuilder * _Nonnull builder) {
  builder.config = feedConfig;
}];
[buzzAdFeed showOn:yourViewController];
```

#### Reward history

A new page displays reward history, which was previously unavailable. You can also open it directly without going through BenefitHub.

**Swift**

```swift
let yourViewController = UIViewController()
let benefitHub = BuzzBenefitHub()
let benefitHubConfig = BuzzBenefitHubConfig.Builder()
  .setQueryParams(BuzzBenefitHubPage.history.toRedirectQueryParams())
  .build()
benefitHub.setConfig(benefitHubConfig)
benefitHub.show(on: yourViewController)
```

**Objective C**

```objectivec
UIViewController *yourViewController = [[UIViewController alloc] init];
BuzzBenefitHubConfig * benefithubConfig = [BuzzBenefitHubConfig configWith:^(BuzzBenefitHubConfigBuilder * _Nonnull builder) {
  builder.queryParams = [BuzzBenefitHubPage.history toRedirectQueryParams];
}];

[self.benefitHub setConfig:benefithubConfig];
[benefitHub showOn:yourViewController];
```

### Implement entry paths in your app UI

Features related to `BZVFeedEntryView` have been removed. Update your implementation to open BenefitHub through `BuzzBenefitHub`, and remove code that uses `BZVFeedEntryView`.

#### Display available reward points

The `availableReward` feature provided through `BZVBuzzAdFeed` has been removed. `BZVBuzzAdFeed.load()` has also been removed, so remove the related code.

### Additional features

#### Integrate BenefitHub as a child view controller

The functionality remains the same, but the class name has changed. Update your code accordingly.

**Swift**

```swift
import BuzzvilSDK

final class ContainerViewController: UIViewController {
  let benefitHub = BuzzBenefitHub()

  override func viewDidLoad() {
    super.viewDidLoad()
    view.backgroundColor = .systemBackground

    displayContentViewController(benefitHub.getViewController())
  }
  
  private func displayContentViewController(_ contentViewController: UIViewController) {
    addChild(contentViewController)
    contentViewController.view.frame = view.bounds
    view.addSubview(contentViewController.view)
    contentViewController.didMove(toParent: self)
  }
}
```

**Objective C**

```objectivec
@import BuzzvilSDK;

@interface ContainerViewController ()

@property (nonatomic, strong, readonly) BuzzBenefitHub *benefitHub;

@end

@implementation ContainerViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  
  _benefitHub = [[BuzzBenefitHub alloc] init];
  [self displayContentViewController:[_benefitHub getViewController]];
}

- (void)displayContentViewController:(UIViewController*)contentViewController {
  [self addChildViewController:contentViewController];
  contentViewController.view.frame = self.view.bounds;
  [self.view addSubview:contentViewController.view];
  [contentViewController didMoveToParentViewController:self];
}

@end
```

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
import BuzzvilSDK

final class ContainerViewController: UIViewController {
  let buzzAdFeed = BZVBuzzAdFeed { builder in }

  override func viewDidLoad() {
    super.viewDidLoad()
    displayContentViewController(buzzAdFeed.viewController)
  }

  private func displayContentViewController(_ contentViewController: UIViewController) {
    addChild(contentViewController)
    contentViewController.view.frame = view.bounds
    view.addSubview(contentViewController.view)
    contentViewController.didMove(toParent: self)
  }
}
```

**Objective C**

```objectivec
@import BuzzvilSDK;

@interface ContainerViewController ()

@property (nonatomic, strong, readonly) BZVBuzzAdFeed *buzzAdFeed;

@end

@implementation ContainerViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  _buzzAdFeed = [BZVBuzzAdFeed feedWithBlock:^(BZVBuzzAdFeedBuilder * _Nonnull builder) {}];
  [self displayContentViewController:[_buzzAdFeed viewController]];
}

- (void)displayContentViewController:(UIViewController*)contentViewController {
  [self addChildViewController:contentViewController];
  contentViewController.view.frame = self.view.bounds;
  [self.view addSubview:contentViewController.view];
  [contentViewController didMoveToParentViewController:self];
}

@end
```

## Native

### Integration

#### Step 1. Prepare

No changes.

#### Step 2. Configure the ad layout

The functionality is almost unchanged, but the class names have changed.

`BZVMediaView` -> `BuzzMediaView` `BZVDefaultCtaView` -> `BuzzDefaultCtaView` `BZVNativeAd2View` -> `BuzzNativeAdView` `BZVNativeAd2ViewBinder` -> `BuzzNativeViewBinder`

The UnitID value has also moved from the constructor of `BuzzNativeViewBinder.Builder()` to `BuzzNative`.

`BZVNativeToFeedView`, which served as a BenefitHub entry point, has been removed. Remove the related code.

**Swift**

```swift
import UIKit
import BuzzvilSDK

final class ViewController: UIViewController {
  private let nativeAdView = BuzzNativeAdView(frame: .zero)
  private let mediaView = BuzzMediaView(frame: .zero)
  private let iconImageView = UIImageView(frame: .zero)
  private let titleLabel = UILabel(frame: .zero)
  private let descriptionLabel = UILabel(frame: .zero)
  private let ctaView = BuzzDefaultCtaView(frame: .zero)

  private lazy var viewBinder = BuzzNativeViewBinder.Builder()
    .nativeAdView(nativeAdView)
    .mediaView(mediaView)
    .iconImageView(iconImageView)
    .titleLabel(titleLabel)
    .descriptionLabel(descriptionLabel)
    .ctaView(ctaView)
    .build()
  
  override func viewDidLoad() {
    super.viewDidLoad()
    
    self.view.addSubview(nativeAdView)
    nativeAdView.addSubview(mediaView)
    nativeAdView.addSubview(iconImageView)
    nativeAdView.addSubview(titleLabel)
    nativeAdView.addSubview(descriptionLabel)
    nativeAdView.addSubview(ctaView)

    // AutoLayout Constraints 설정 
    // ...
  }
}
```

**Objective-C**

```objectivec
@import BuzzvilSDK;

@interface ViewController ()

@property (nonatomic, strong, readonly) BuzzNativeAdView *nativeAdView;
@property (nonatomic, strong, readonly) BuzzMediaView *mediaView;
@property (nonatomic, strong, readonly) UIImageView *iconImageView;

@property (nonatomic, strong, readonly) UILabel *descriptionLabel;
@property (nonatomic, strong, readonly) BuzzDefaultCtaView *ctaView;
@property (nonatomic, strong, readonly) BuzzNativeViewBinder *viewBinder;

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  _nativeAdView = [[BuzzNativeAdView alloc] initWithFrame:CGRectZero];
  [self.view addSubview:_nativeAdView];

  _mediaView = [[BuzzMediaView alloc] initWithFrame:CGRectZero];
  [_nativeAdView addSubview:_mediaView];

  _iconImageView = [[UIImageView alloc] initWithFrame:CGRectZero];
  [_nativeAdView addSubview:_iconImageView];

  _titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
  [_nativeAdView addSubview:_titleLabel];

  _descriptionLabel = [[UILabel alloc] initWithFrame:CGRectZero];
  [_nativeAdView addSubview:_descriptionLabel];

  _ctaView = [[BuzzDefaultCtaView alloc] initWithFrame:CGRectZero];
  [_nativeAdView addSubview:_ctaView];
  
  _viewBinder = [BuzzNativeViewBinder viewBinderWithk:^(BuzzNativeViewBinderBuilder * _Nonnull builder) {
    builder.nativeAdView = self.nativeAdView;
    builder.mediaView = self.mediaView;
    builder.iconImageView = self.iconImageView;
    builder.titleLabel = self.titleLabel;
    builder.descriptionLabel = self.descriptionLabel;
    builder.ctaView = self.ctaView;
  }];

  // AutoLayout Constraints 설정

```

**Objective-C**

```objectivec

  [self.view addSubview:_nativeToFeedView];

  [_nativeToFeedView setWithUnitId:@"YOUR_NATIVE_UNIT_ID"];

  // AutoLayout Constraints 설정
  // ...
}

@end
```

#### Step 3. Display ads

The `BZVNativeAd2ViewBinder.bind()` function used for ad allocation has been replaced by `BuzzNative.load()`. Ads allocated by `BuzzNative` are now displayed through `ViewBinder`. Update your ad allocation code accordingly.

@end
```

##### Display the base reward amount

Displaying base rewards in advance has been removed. The `BuzzAdBenefit.getAvailableFeedBaseReward()` function has also been removed, so remove the related code.

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
BuzzAdBenefit.getAvailableFeedBaseReward(for: YOUR_FEED_UNIT_ID) { [weak self] (reward) in
  guard let self = self else { return }
  if reward > 0 {
    self.nativeToFeedLabel.text = "\(reward) 포인트 받고 더 많은 참여 기회 보기"
  } else {
    self.nativeToFeedLabel.text = "더 많은 참여 기회 보기"
  }
}
```

**Objective-C**

```objectivec
__weak typeof(self) weakSelf = self;
[BuzzAdBenefit getAvailableFeedBaseRewardFor:@"YOUR_FEED_UNIT_ID" onComplete:^(NSInteger reward) {
  __strong typeof(self) strongSelf = weakSelf;
  if (strongSelf) {
    if (reward > 0) {
      strongSelf.nativeToFeedLabel.text = [NSString stringWithFormat:@"%d 포인트 받고 더 많은 참여 기회 보기", reward];
    } else {
      strongSelf.nativeToFeedLabel.text = @"더 많은 참여 기회 보기";
    }
  }
}];
```

### Additional features

#### Register a video ad listener

Video ad listeners have been removed because native placements do not provide video ads. The `BZVNativeAdViewVideoDelegate` protocol has been removed; remove the related code.

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
import UIKit
import BuzzvilSDK

final class ViewController: UIViewController {
  private let nativeAd2View = BZVNativeAd2View(frame: .zero)
  // ...생략...

  override func viewDidLoad() {
    // ...생략...
    nativeAd2View.videoDelegate = self
  }
}

// MARK: BZVNativeAdViewVideoDelegate
extension ViewController: BZVNativeAdViewVideoDelegate {
  func bzvNativeAdView(_ nativeAdView: BZVNativeAdView, willStartPlayingVideoAd nativeAd: BZVNativeAd) {
    // 비디오 광고의 비디오가 시작하기 직전에 호출됩니다.
  }

  func bzvNativeAdView(_ nativeAdView: BZVNativeAdView, didResumeVideoAd nativeAd: BZVNativeAd) {
    // 비디오 광고의 비디오가 재생되면 호출됩니다.
  }

  func bzvNativeAdView(_ nativeAdView: BZVNativeAdView, willReplayVideoAd nativeAd: BZVNativeAd) {
    // 비디오 광고의 비디오가 리플레이되면 호출됩니다.
  }

  func bzvNativeAdView(_ nativeAdView: BZVNativeAdView, didPauseVideoAd nativeAd: BZVNativeAd) {
    // 비디오 광고의 비디오가 일시정지되면 호출됩니다.
  }

  func bzvNativeAdView(_ nativeAdView: BZVNativeAdView, didFinishPlayingVideoAd nativeAd: BZVNativeAd) {
    // 비디오 광고의 비디오가 종료되면 호출됩니다.
  }
}
```

**Objective-C**

```objectivec
@import BuzzvilSDK;

@interface ViewController () <BZVNativeAdViewVideoDelegate>

@property (nonatomic, strong, readonly) BZVNativeAd2View *nativeAd2View;
// ...생략...

@end

@implementation ViewController

- (void)viewDidLoad {
  // ...생략...
  _nativeAd2View.videoDelegate = self;
}

#pragma mark - BZVNativeAdViewVideoDelegate
- (void)BZVNativeAdView:(BZVNativeAdView *)nativeAdView willStartPlayingVideoAd:(BZVNativeAd *)nativeAd {
  // 비디오 광고의 비디오가 시작하기 직전에 호출됩니다.
}

- (void)BZVNativeAdView:(BZVNativeAdView *)nativeAdView didResumeVideoAd:(BZVNativeAd *)nativeAd {
  // 비디오 광고의 비디오가 재생되면 호출됩니다.
}

  // 비디오 광고의 비디오가 리플레이되면 호출됩니다.
}

  // 비디오 광고의 비디오가 일시정지되면 호출됩니다.
}

- (void)BZVNativeAdView:(BZVNativeAdView *)nativeAdView didFinishPlayingVideoAd:(BZVNativeAd *)nativeAd {
  // 비디오 광고의 비디오가 종료되면 호출됩니다.
}

@end
```

#### Register an ad event listener

Ad events previously received through `BZVNativeAd2ViewBinder` are now received through the `BuzzNative` object. Update your code accordingly.

**Swift**

```swift
final class ViewController: UIViewController {
  // ...생략...

  override func viewDidLoad() {
    // ...생략...

    // Native 광고 이벤트 처리를 위한 closure를 등록하고 각 이벤트에 따라 필요한 기능을 구현합니다.
    // Warning: retain cycle 방지를 위해 closure 내에서 반드시 weak self를 사용해주세요.
    native.subscribeAdEvents(onImpressed: { [weak self] nativeAd in
      // Native 광고가 유저에게 노출되었을 때 호출됩니다.
    }, onClicked: { [weak self] nativeAd in
      // 유저가 Native 광고를 클릭했을 때 호출됩니다.
    }, onRewardRequested: { [weak self] nativeAd in
      // 리워드 적립 요청시에 호출됩니다.
    }, onRewarded: { [weak self] nativeAd, rewardResult in
      // 리워드 적립 결과를 수신했을 때 호출됩니다.
    }, onParticipated: { [weak self] nativeAd in
      // 광고 참여가 완료되었을 때 호출됩니다.
    })

    // ...생략...
  }
}
```

**Objective-C**

```objectivec
@implementation ViewController

- (void)viewDidLoad {
  // ...생략...
  
  // Native 광고 이벤트 처리를 위한 closure를 등록하고 각 이벤트에 따라 필요한 기능을 구현합니다.

#### Reward results (`BZVRewardResult`)

The class has been renamed from `BZVRewardResult` to `BuzzRewardResult`. See [Reward result types (`BuzzRewardResult`)](https://docs.buzzvil.com/en/docs/buzzbenefit-ios/v6/native#%EB%A6%AC%EC%9B%8C%EB%93%9C-%EC%A0%81%EB%A6%BD-%EA%B2%B0%EA%B3%BCbuzzrewardresult-%EC%A2%85%EB%A5%98).

#### Implement a carousel

##### Implement basic carousel features

###### Step 1. Allocate ads

The classes and functions have changed. Update your code using the table below.

| AS-IS                        | TO-BE                    |
| ---------------------------- | ------------------------ |
| `BZVNativeAd2Pool`           | `BuzzNativeGroup`        |
| `BZVNativeAd2Pool.loadAds()` | `BuzzNativeGroup.load()` |
| `completionHandler`          | `onSuccess`              |
| `errorHandler`               | `onFailure`              |

  private let unitId = "YOUR_UNIT_ID"
  
  // 최대 10개의 광고를 요청할 수 있습니다.

@interface CarouselViewController ()

// 최대 10개의 광고를 요청할 수 있습니다.
@property (nonatomic, assign, readonly) NSInteger adRequestCount;

  }];
}

@end
```

###### Step 2. Implement UICollectionViewCell

In your existing `UICollectionViewCell`, replace the implementation using `setPoool()` with `bind(with native: BuzzNative)`. Pass the `BuzzNative` object to the UICollectionViewCell and add the necessary code.

**Swift**

```swift
final class CarouselCell: UICollectionViewCell {
  // ...

  private lazy var viewBinder = BuzzNativeViewBinder.Builder()
    .nativeAdView(nativeAdView)
    .mediaView(mediaView)
    .iconImageView(iconImageView)
    .titleLabel(titleLabel)
    .descriptionLabel(descriptionLabel)
    .ctaView(ctaView)
    .build()
  
  // ...

  override func prepareForReuse() {
    super.prepareForReuse()
    // prepareForReuse 내에서 unbind를 반드시 호출하여 cell을 재사용할 때 문제가 발생하지 않게 합니다.
    viewBinder.unbind()
  }

  // collectionView의 collectionView(_:cellForItemAt:) 시점에 호출합니다.
  func bind(with native: BuzzNative) {
   // bind()를 호출하면 할당된 광고 표시 및 갱신이 자동으로 수행됩니다.
    viewBinder.bind(native)
  }
}
```

**Objective-C**

```objectivec
@interface CarouselCell : UICollectionViewCell

- (void)bind:(BuzzNativeAd *)native;

@end

@interface CarouselCell ()

// ...
@property (nonatomic, strong, readonly) BuzzNativeViewBinder *viewBinder;

@end

@implementation CarouselCell

// ...

- (void)prepareForReuse {
  [super prepareForReuse];
  // prepareForReuse 내에서 unbind를 반드시 호출하여 cell을 재사용할 때 문제가 발생하지 않게 합니다.

###### BenefitHub entry slide

This feature has been removed along with `BZVFeedPromotionView` and `BZVFeedPromotionViewBinder`. Remove them from your code. Also remove `FeedPromitionCell` from the previous guide.

###### Open BenefitHub

The `BZVFeedEntryView` class used as a BenefitHub entry point has been removed. Replace it with code that opens BenefitHub, as shown below.

**Swift**

```swift
let yourViewController = UIViewController()
let benefitHub = BuzzBenefitHub()
benefitHub.show(on: yourViewController)
```

**Objective C**

```objectivec
UIViewController *yourViewController = [[UIViewController alloc] init];
BuzzBenefitHub *benefitHub = [[BuzzBenefitHub alloc] init];
[benefitHub showOn:yourViewController];
```

##### Implement optional carousel features

###### Implement a loading screen

The previously separate function has moved into `bind(with native: BuzzNative)` in the UICollectionViewCell.

###### Register an ad event listener

The function and its location have changed: it is now inside bind(). The previously separate function has moved into `bind(with native: BuzzNative)` in the UICollectionViewCell. Register it through a `BuzzNative` object instead of the previous `BZVNativeAd2ViewBinder` class.

**Swift**

```swift
final class CarouselCell: UICollectionViewCell {
  // ...
  
  func bind(with native: BuzzNative) {
    // ...

      },

      }, 
      onParticipated: { [weak self] in

## Interstitial

### Integration

#### Step 1. Prepare

No changes.

#### Step 2. Allocate and display ads

The class names and protocols have changed. Update your code using the examples below.

The interstitial object has changed from `BZVBuzzAdInterstitial` to `BuzzInterstitial`. Initialization of `BuzzInterstitial` has changed. Update your code as shown below. The delegate protocol has changed from `BZVBuzzAdInterstitialDelegate` to BuzzInterstitialDelegate.

**Swift**

```swift
import UIKit
import BuzzvilSDK

final class ViewController: UIViewController, BuzzInterstitialDelegate {
  let buzzAdInterstitial = BuzzInterstitial(unitId: "YOUR_INTERSTITIAL_UNIT_ID", type: .dialog)

  override func viewDidLoad() {
    super.viewDidLoad()

    buzzAdInterstitial.delegate = self
    buzzAdInterstitial.load()
  }
}
extension ViewController: BuzzInterstitialDelegate {
  func BuzzInterstitialDidLoadAd(_ interstitial: BuzzInterstitial) {
    // 할당된 광고가 있으면 호출됩니다.
    // Interstitial 광고를 화면에 표시합니다.
    interstitial.present(on: self)
  }
  
  func BuzzInterstitialDidFail(toLoadAd interstitial: BuzzInterstitial, withError error: Error) {
    // 할당된 광고가 없으면 호출됩니다.
  }
  
  func BuzzInterstitialDidDismiss(_ viewController: UIViewController) {
    // Interstitial 지면이 종료되면 호출됩니다.
    // 필요에 따라 추가 기능을 구현하세요.
  }
}
```

**Objective-C**

```objectivec
@import BuzzvilSDK;

@interface ViewController () <BuzzInterstitialDelegate>

@property (nonatomic, strong, readonly) BuzzInterstitial *buzzAdInterstitial;

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  _buzzAdInterstitial = [[BuzzInterstitial alloc] initWithUnitId:@"YOUR_INTERSTITIAL_UNIT_ID" type:BuzzInterstitialTypeDialog];
  _buzzAdInterstitial.delegate = self;
  [_buzzAdInterstitial load];
}

#pragma mark - BuzzInterstitialDelegate
- (void)BuzzInterstitialDidLoadAd:(BuzzInterstitial *)interstitial {
  // 할당된 광고가 있으면 호출됩니다.
  // Interstitial 광고를 화면에 표시합니다.
  [interstitial presentOnViewController:self];
}

- (void)BuzzInterstitialDidFailToLoadAd:(BuzzInterstitial *)interstitial withError:(NSError *)error {
  // 할당된 광고가 없으면 호출됩니다.
}

- (void)BuzzInterstitialDidDismiss:(UIViewController *)viewController {
  // Interstitial 지면이 종료되면 호출됩니다.
  // 필요에 따라 추가 기능을 구현하세요.
}

@end
```

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

import UIKit
import BuzzvilSDK

final class ViewController: UIViewController, BZVBuzzAdInterstitialDelegate {
  let buzzAdInterstitial = BZVBuzzAdInterstitial { builder in
    builder.unitId = "YOUR_INTERSTITIAL_UNIT_ID"
    builder.type = .dialog
  }

  override func viewDidLoad() {
    super.viewDidLoad()

    buzzAdInterstitial.delegate = self
    buzzAdInterstitial.load()
  }
}
extension ViewController: BZVBuzzAdInterstitialDelegate {
  func bzvBuzzAdInterstitialDidLoadAd(_ interstitial: BZVBuzzAdInterstitial) {
    // 할당된 광고가 있으면 호출됩니다.

    interstitial.present(on: self)
  }
  
  func bzvBuzzAdInterstitialDidFail(toLoadAd interstitial: BZVBuzzAdInterstitial, withError error: Error) {
    // 할당된 광고가 없으면 호출됩니다.
  }
  
  func bzvBuzzAdInterstitialDidDismiss(_ viewController: UIViewController) {
    // Interstitial 지면이 종료되면 호출됩니다.
    // 필요에 따라 추가 기능을 구현하세요.
  }
}
```

  }];
  _buzzAdInterstitial.delegate = self;
  [_buzzAdInterstitial load];
}

#pragma mark - BZVBuzzAdInterstitialDelegate
- (void)BZVBuzzAdInterstitialDidLoadAd:(BZVBuzzAdInterstitial *)interstitial {
  // 할당된 광고가 있으면 호출됩니다.
  // Interstitial 광고를 화면에 표시합니다.
  [interstitial presentOnViewController:self];
}

- (void)BZVBuzzAdInterstitialDidFailToLoadAd:(BZVBuzzAdInterstitial *)interstitial withError:(NSError *)error {
  // 할당된 광고가 없으면 호출됩니다.
}

- (void)BZVBuzzAdInterstitialDidDismiss:(UIViewController *)viewController {
  // Interstitial 지면이 종료되면 호출됩니다.
  // 필요에 따라 추가 기능을 구현하세요.
}

@end
```

### Step 3. Add a BenefitHub entry point to the interstitial

The option to add a button that opens BenefitHub from an interstitial has changed. The entry point is now always visible instead of optional. Remove the existing `buzzAdBenefitRouter` code.

**Swift**

```swift
let feedConfig = BZVFeedConfig { builder in
  builder.unitID = "YOUR_FEED_UNIT_ID"
}

let buzzAdInterstitial = BZVBuzzAdInterstitial { builder in
  builder.unitId = "YOUR_INTERSTITIAL_UNIT_ID"
  builder.type = .dialog
  builder.buzzAdBenefitRouter = BuzzBenefitRouterFactory.createFeedRouter(feedConfig) // 삭제 처리
}
```

**Objective-C**

```objectivec
BZVFeedConfig *feedConfig = [BZVFeedConfig configWithBlock:^(BZVFeedConfigBuilder * _Nonnull builder) {
  builder.unitID = @"YOUR_FEED_UNIT_ID";
}];

BZVBuzzAdInterstitial *buzzAdInterstitial = [BZVBuzzAdInterstitial interstitialWithBlock:^(BZVBuzzAdInterstitialBuilder * _Nonnull builder) {
  builder.unitId = @"YOUR_INTERSTITIAL_UNIT_ID";
  builder.type = BZVBuzzAdInterstitialTypeDialog;
  builder.buzzAdBenefitRouter = [BuzzBenefitRouterFactory createFeedRouter:feedConfig];
}];
```

## BuzzBanner

The class names have changed. Review the changes below and update them accordingly.

| AS-IS                           | TO-BE                  |

## UI configuration

Most theme-related code has been removed; only custom CTA button implementation remains. Remove the other color-related code. To configure the primary color through server settings, contact your Buzzvil representative at <help@buzzvil.com>.

### Implement a custom CTA button

The protocol required to implement a custom CTA button has been renamed. `BZVCtaViewProtocol` -> `BuzzCtaViewProtocol`

**Swift**

```swift
// MARK: BZVCtaViewProtocol
protocol BZVCtaViewProtocol {
  // 리워드가 없는 광고에 대한 CTA 뷰 레이아웃을 정의합니다.
  func renderRewardNotAvailableViewState(withCtaText ctaText: String)

  // 리워드가 있는 광고에 대한 CTA 뷰 레이아웃을 정의합니다.
  func renderRewardAvailableViewState(withCtaText ctaText: String, reward: Int)

  // 참여 확인 중인 광고에 대한 CTA 뷰 레이아웃을 정의합니다.
  func renderParticipatingViewState(withCtaText ctaText: String)

  // 참여 완료한 광고에 대한 CTA 뷰 레이아웃을 정의합니다.
  func renderParticipatedViewState(withCtaText ctaText: String)
}
```

**Objective-C**

```objectivec
@objc
public protocol BuzzCtaViewProtocol: AnyObject {
  @objc
  func renderParticipatingViewState(ctaText: String)
  
  @objc
  func renderParticipatedViewState(ctaText: String)
  
  @objc
  func renderRewardAvailableViewState(ctaText: String, reward: Int)
  
  @objc
  func renderRewardNotAvailableViewState(ctaText: String)
}
```

## Custom in-app browser

This version does not support a custom in-app browser. Remove the previous `BuzzAdBrowser`, `BZVLauncher`, and `BZVLauncherDelegate` code.

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
import UIKit
import BuzzvilSDK

final class CustomBrowserViewController: UIViewController {
  private lazy var browserViewController: UIViewController = {
    BuzzAdBrowser.sharedInstance().browserViewController()
  }()
  
  override func viewDidLoad() {
    super.viewDidLoad()
    
    displayContentViewController(browserViewController)
  }

  private func displayContentViewController(_ contentViewController: UIViewController) {
    addChild(contentViewController)
    contentViewController.view.frame = view.bounds
    view.addSubview(contentViewController.view)
    contentViewController.didMove(toParent: self)
  }
}
```

**Objective-C**

```objectivec
@interface CustomBrowserViewController: UIViewController

@end

@interface CustomBrowserViewController ()

@property (nonatomic, strong, readonly) UIViewController *browserViewController;

@end

@implementation CustomBrowserViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  _browserViewController = [BuzzAdBrowser.sharedInstance browserViewController];
  [self displayContentViewController:_browserViewController];
}

- (void)displayContentViewController:(UIViewController *)contentViewController {
  [self addChildViewController:contentViewController];
  contentViewController.view.frame = self.view.bounds;
  [self.view addSubview:contentViewController.view];
  [contentViewController didMoveToParentViewController:self];
}

@end
```

**Swift**

```swift
import Foundation
import BuzzvilSDK

final class CustomLauncher: NSObject, BZVLauncher {
  // 런처와 관련된 이벤트를 수신할 수 있습니다.
  var delegate: BZVLauncherDelegate?

  func open(with launchInfo: BZVLaunchInfo) {
    // launchInfo의 인자를 확인하여 광고 또는 콘텐츠인지 미리 판단할 수 있습니다.
    if let ad = launchInfo.ad {
      if ad.isDeepLink {
        // 딥링크 광고일 경우 필요한 작업을 할 수 있습니다.
      }
    } else if let article = launchInfo.article {
      let sourceURL = article.sourceURL
    }

    let customBrowserViewController = CustomBrowserViewController()
    YOUR_ROOT_VIEW_CONTROLLER.presentedViewController?.present(customBrowserViewController, animated: true, completion: nil)
  }
}
```

**Objective-C**

```objectivec
@import BuzzvilSDK;

@interface CustomLauncher : NSObject <BZVLauncher>

// 런처와 관련된 이벤트를 수신할 수 있습니다.
@property (nonatomic, weak, readwrite, nullable) id<BZVLauncherDelegate> delegate;

@end

@implementation CustomLauncher

- (void)openWithLaunchInfo:(BZVLaunchInfo *)launchInfo {
  // launchInfo의 인자를 확인하여 광고 또는 콘텐츠인지 미리 판단할 수 있습니다.
  if (launchInfo.ad != nil) {
    if (launchInfo.ad.isDeepLink) {
      // 딥링크 광고일 경우 필요한 작업을 할 수 있습니다.
    }
  } else if (launchInfo.article != nil){
    NSString *sourceURL = launchInfo.article.sourceURL;
  }

  // Custom Browser 실행
  CustomBrowserViewController *customBrowserViewController = [[CustomBrowserViewController alloc] init];
  [YOUR_ROOT_VIEW_CONTROLLER.presentedViewController presentViewController:customBrowserViewController animated:YES completion:nil];
}

@end
```

**Swift**

```swift
let launcher = CustomLauncher()
BuzzAdBenefit.setLauncher(launcher)
```

**Objective-C**

```objectivec
CustomLauncher *launcher = [[CustomLauncher alloc] init];
[BuzzAdBenefit setLauncher:launcher];
```

## Agree to the privacy policy

The functions for checking privacy policy consent and providing consent have changed.

| Status | enum                               |
| ------ | ---------------------------------- |
| Agreed | `BuzzPrivacyConsentStatus.granted` |
| Denied | `BuzzPrivacyConsentStatus.revoked` |

**Swift**

```swift
BuzzAdBenefit.shared.loadPrivacyConsentStatus(onSuccess: { [weak self] status in
  // 현재 개인정보 처리 방침 상태를 가져올 수 있습니다
}, onFailure: { [weak self] error in
  // 개인정보 처리방침에 대한 상태를 가져오는데 실패 했을 경우 호출 됩니다.
})

BuzzAdBenefit.shared.grantPrivacyConsent(onSuccess: { [weak self] in
  // 개인정보 처리방침 동의에 성공했을 경우 호출 됩니다.
}, onFailure: { [weak self] error in
  // 개인정보 처리방침 동의 요청에 실패했을 경우 호출 됩니다.
})
```

**Objective-C**

```objectivec
[BuzzAdBenefit.sharedInstance loadPrivacyConsentStatusOnSuccess:^(enum BuzzPrivacyConsentStatus status) {
  // 현재 개인정보 처리 방침 상태를 가져올 수 있습니다
} onFailure:^(NSError * _Nonnull error) {
  // 개인정보 처리방침에 대한 상태를 가져오는데 실패 했을 경우 호출 됩니다.
}];

[BuzzAdBenefit.sharedInstance grantPrivacyConsentOnSuccess:^{
  // 개인정보 처리방침 동의에 성공했을 경우 호출 됩니다.
} onFailure:^(NSError * _Nonnull error) {
  // 개인정보 처리방침 동의 요청에 실패했을 경우 호출 됩니다.
}];

```

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
let privacyPolicyManager = BuzzAdBenefit.privacyPolicyManager

// 직접 구현한 개인정보 제3자 제공 동의 UI에서 동의를 받았을 경우 아래 코드를 실행하면, 피드 화면에서 개인정보 제3자 제공 동의 UI가 노출되지 않으면서 광고 할당이 정상적으로 진행 됩니다.
// 아래의 코드를 실행하지 않을 경우 피드 진입 시 개인정보 제3자 제공 동의 UI가 노출되기 때문에 필수적으로 실행이 필요합니다.
privacyPolicyManager.grantConsent()

// 아래 코드를 통해서 수집 동의를 철회할 수 있습니다. 이 코드가 실행되면 피드에서 광고 할당이 이루어지지 않습니다.
privacyPolicyManager.revokeConsent()
```

**Objective-C**

```objectivec
BZVPrivacyPolicyManager *privacyPolicyManager = [BuzzAdBenefit privacyPolicyManager];

// 직접 구현한 개인정보 제3자 제공 동의 UI 에서 동의를 받았을 경우 아래 코드를 실행하면, 피드 화면에서 개인정보 제3자 제공 동의 UI가 노출되지 않으면서 광고 할당이 정상적으로 진행 됩니다.
// 아래의 코드를 실행하지 않을 경우 피드 진입 시 개인정보 제3자 제공 동의 UI가 노출되기 때문에 필수적으로 실행이 필요합니다.
[privacyPolicyManager grantConsent];

// 아래 코드를 통해서 수집 동의를 철회할 수 있습니다. 이 코드가 실행되면 피드에서 광고 할당이 이루어지지 않습니다.
[privacyPolicyManager revokeConsent];
```

## Mission Pack

The standalone `BuzzAdMissionPack` class has been removed and merged into `BuzzBenefitHub`. Remove the related code.

Reference — Previous code (BuzzAdBenefit SDK v5)

**Swift**

```swift
import UIKit
import BuzzvilSDK

class MissionPackViewController: UIViewController {
  let missionPack = BuzzAdBenefitMissionPack(unitId: "YOUR_MISSION_PACK_UNIT_ID")
  
  override func viewDidLoad() {
    super.viewDidLoad()
    
    showMissionPack()
  }
  
  // missionPack 사용가능한지 체크하기
  func checkCanOpenMissionPack() {
    missionPack.canOpen {
      print ("MissionPack Can open !")
    } onFailure: { error in
      print ("MissionPack Can't open error: \(error.localizedDescription)")
    }
  }
  
  // missionPack 화면에 표시하기
  func showMissionPack() {
    missionPack.show(on: self, onFailure: { error in
      print ("MissionPack Can't open error: \(error.localizedDescription)")
    })
  }
}
```

**Objective-C**

```objectivec
@import BuzzvilSDK;
#import "MissionPackViewController.h"

@interface MissionPackViewController()

@property (nonatomic, strong, readonly) BuzzAdBenefitMissionPack * missionPack;

@end

@implementation MissionPackViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  
  _missionPack = [[BuzzAdBenefitMissionPack alloc] initWithUnitId:@"YOUR_MISSION_PACK_UNIT_ID"];
}

- (void)checkCanOpenMissionPack {
  [_missionPack canOpenOnSuccess:^{
    // missionPack 이 열릴 수 있을 때 호출 됩니다.
  } onFailure:^(NSError * _Nonnull error) {
    // missionPack 이 열릴 수 없을 때 호출 됩니다.
  }];
}

- (void)showMissionPack {
  [_missionPack showOn:self onFailure:^(NSError * _Nonnull error) {
    // missionPack 이 열릴 수 없을 때 호출 됩니다.
  }];
}

@end

```
