插页式激励广告（Beta 版）

插页式激励广告是一种 一种利诱性质的广告格式，可让您为每次展示 自动应用。与激励广告不同，用户 用户才能选择观看插页式激励广告。

前提条件

• Google 移动广告 SDK 7.60.0 或更高版本。
• 完成入门指南。

实现

植入插页式激励广告的主要步骤如下所示：

• 加载广告
• [可选] 验证 SSV 回调
• 注册回调
• 展示广告并处理奖励事件

加载广告

广告的加载是使用 load(adUnitID:request) 完成的。 （针对 GADRewardedInterstitialAd 类）。

Swift

import GoogleMobileAds
import UIKit

class ViewController: UIViewController {

  private var rewardedInterstitialAd: GADRewardedInterstitialAd?

  override func viewDidLoad() {
    super.viewDidLoad()

    Task {
      do {
        rewardedInterstitialAd = try await GADRewardedInterstitialAd.load(
          withAdUnitID: "ca-app-pub-3940256099942544/6978759866", request: GADRequest())
      } catch {
        print("Failed to load rewarded interstitial ad with error: \(error.localizedDescription)")
      }
    }
  }
}

SwiftUI

import GoogleMobileAds

class RewardedInterstitialViewModel: NSObject, ObservableObject,
  GADFullScreenContentDelegate
{
  @Published var coins = 0
  private var rewardedInterstitialAd: GADRewardedInterstitialAd?

  func loadAd() async {
    do {
      rewardedInterstitialAd = try await GADRewardedInterstitialAd.load(
        withAdUnitID: "ca-app-pub-3940256099942544/6978759866", request: GADRequest())
      rewardedInterstitialAd?.fullScreenContentDelegate = self
    } catch {
      print(
        "Failed to load rewarded interstitial ad with error: \(error.localizedDescription)")
    }
  }
RewardedInterstitialViewModel.swift

Objective-C

#import "ViewController.h"

@interface ViewController ()
@property(nonatomic, strong) GADRewardedInterstitialAd* rewardedInterstitialAd;
@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  [GADRewardedInterstitialAd
      loadWithAdUnitID:@"<var label='the ad unit ID'>ca-app-pub-3940256099942544/6978759866</var>"
                request:[GADRequest request]
      completionHandler:^(
          GADRewardedInterstitialAd* _Nullable rewardedInterstitialAd,
          NSError* _Nullable error) {
        if (!error) {
          self.rewardedInterstitialAd = rewardedInterstitialAd;
        }
      }
  ];
}

提示： 您可以使用广告加载调用为预加载的广告积累缓存，然后再 以便在需要时能够零延迟地展示广告。 由于广告在一小时后过期，因此您应清除此缓存并使用新的 。

[可选] 验证服务器端验证 (SSV) 回调

需要在服务器端获取额外数据的应用 验证回调应使用 自定义数据功能。在激励广告上设置的任何字符串值 对象会传递给 SSV 回调的 custom_data 查询参数。如果拒绝 自定义数据值后，custom_data 查询参数值不会 。

以下代码示例演示了如何为激励广告设置自定义数据 插页式广告对象。

Swift

do {
  rewardedInterstitialAd = try await GADRewardedInterstitialAd.load(
    withAdUnitID: "ca-app-pub-3940256099942544/6978759866", request: GADRequest())
  let options = GADServerSideVerificationOptions()
  options.customRewardString = "SAMPLE_CUSTOM_DATA_STRING"
  rewardedInterstitialAd.serverSideVerificationOptions = options
} catch {
  print("Rewarded ad failed to load with error: \(error.localizedDescription)")
}

Objective-C

[GADRewardedInterstitialAd
    loadWithAdUnitID:@"ca-app-pub-3940256099942544/6978759866"
              request:GADRequest
    completionHandler:^(GADRewardedInterstitialAd *ad, NSError *error) {
      if (error) {
        // Handle Error
        return;
      }
      self.rewardedInterstitialAd = ad;
      GADServerSideVerificationOptions *options =
          [[GADServerSideVerificationOptions alloc] init];
      options.customRewardString = @"SAMPLE_CUSTOM_DATA_STRING";
      ad.serverSideVerificationOptions = options;
    }];

要点 ：自定义奖励字符串为百分比 经过转义，可能需要解码 从 SSV 回调解析而来。

注册回调

要接收有关展示事件的通知，您必须实现 GADFullScreenContentDelegate 协议，并将其分配给 返回的广告的 fullScreenContentDelegate 属性。通过 GADFullScreenContentDelegate 协议负责在广告 展示成功或失败，以及何时关闭。以下代码演示了如何实现此协议并将其分配给广告：

Swift

import GoogleMobileAds
import UIKit

class ViewController: UIViewController, GADFullScreenContentDelegate {

  private var rewardedInterstitialAd: GADRewardedInterstitialAd?

  override func viewDidLoad() {
    super.viewDidLoad()

    Task {
      do {
        rewardedInterstitialAd = try await GADRewardedInterstitialAd.load(
          withAdUnitID: "ca-app-pub-3940256099942544/6978759866", request: GADRequest())
        self.rewardedInterstitialAd?.fullScreenContentDelegate = self
      } catch {
        print("Failed to load rewarded interstitial ad with error: \(error.localizedDescription)")
      }
    }
  }

  /// Tells the delegate that the ad failed to present full screen content.
  func ad(_ ad: GADFullScreenPresentingAd, didFailToPresentFullScreenContentWithError error: Error) {
    print("Ad did fail to present full screen content.")
  }

  /// Tells the delegate that the ad will present full screen content.
  func adWillPresentFullScreenContent(_ ad: GADFullScreenPresentingAd) {
    print("Ad will present full screen content.")
  }

  /// Tells the delegate that the ad dismissed full screen content.
  func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
    print("Ad did dismiss full screen content.")
  }
}

SwiftUI

将 fullScreenContentDelegate 属性分配给返回的广告：

rewardedInterstitialAd?.fullScreenContentDelegate = self
RewardedInterstitialViewModel.swift

实现协议：

func adDidRecordImpression(_ ad: GADFullScreenPresentingAd) {
  print("\(#function) called")
}

func adDidRecordClick(_ ad: GADFullScreenPresentingAd) {
  print("\(#function) called")
}

func ad(
  _ ad: GADFullScreenPresentingAd,
  didFailToPresentFullScreenContentWithError error: Error
) {
  print("\(#function) called")
}

func adWillPresentFullScreenContent(_ ad: GADFullScreenPresentingAd) {
  print("\(#function) called")
}

func adWillDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
  print("\(#function) called")
}

func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
  print("\(#function) called")
  // Clear the rewarded interstitial ad.
  rewardedInterstitialAd = nil
}
RewardedInterstitialViewModel.swift

Objective-C

@interface ViewController () <GADFullScreenContentDelegate>
@property(nonatomic, strong) GADRewardedInterstitialAd *rewardedInterstitialAd;
@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  // Do any additional setup after loading the view.

  [GADRewardedInterstitialAd
      loadWithAdUnitID:@"ca-app-pub-3940256099942544/6978759866"
                request:[GADRequest request]
      completionHandler:^(
          GADRewardedInterstitialAd *_Nullable rewardedInterstitialAd,
          NSError *_Nullable error) {
        if (!error) {
          self.rewardedInterstitialAd = rewardedInterstitialAd;
          self.rewardedInterstitialAd.fullScreenContentDelegate = self;
        }
      }];
}

/// Tells the delegate that the ad failed to present full screen content.
- (void)ad:(nonnull id<GADFullScreenPresentingAd>)ad
didFailToPresentFullScreenContentWithError:(nonnull NSError *)error {
    NSLog(@"Ad did fail to present full screen content.");
}

/// Tells the delegate that the ad will present full screen content.
- (void)adWillPresentFullScreenContent:(nonnull id<GADFullScreenPresentingAd>)ad {

    NSLog(@"Ad will present full screen content.");
}

/// Tells the delegate that the ad dismissed full screen content.
- (void)adDidDismissFullScreenContent:(nonnull id<GADFullScreenPresentingAd>)ad {
  NSLog(@"Ad did dismiss full screen content.");
}

展示广告并处理奖励事件

要点 ：在向用户展示插页式激励广告之前，您必须 向用户显示一个介绍画面，其中提供明确的奖励消息，并且 提供在广告开始播放前跳过广告的选项。 了解详情。

展示广告时，您必须提供 GADUserDidEarnRewardHandler 对象 处理用户的奖励。

以下代码展示了展示激励广告的最佳方法 插页式广告。

Swift

func show() {
  guard let rewardedInterstitialAd = rewardedInterstitialAd else {
    return print("Ad wasn't ready.")
  }

  // The UIViewController parameter is an optional.
  rewardedInterstitialAd.present(fromRootViewController: nil) {
    let reward = rewardedInterstitialAd.adReward
    print("Reward received with currency \(reward.amount), amount \(reward.amount.doubleValue)")
    // TODO: Reward the user.
  }
}

SwiftUI

监听视图中的界面事件以展示广告。

var rewardedInterstitialBody: some View {
  // ...
  }
  .onChange(
    of: showAd,
    perform: { newValue in
      if newValue {
        viewModel.showAd()
      }
    }
  )
RewardedInterstitialContentView.swift

通过观看模型展示插页式激励广告：

func showAd() {
  guard let rewardedInterstitialAd = rewardedInterstitialAd else {
    return print("Ad wasn't ready.")
  }

  rewardedInterstitialAd.present(fromRootViewController: nil) {
    let reward = rewardedInterstitialAd.adReward
    print("Reward amount: \(reward.amount)")
    self.addCoins(reward.amount.intValue)
  }
}
RewardedInterstitialViewModel.swift

Objective-C

- (void)show {
  // The UIViewController parameter is nullable.
  [_rewardedInterstitialAd presentFromRootViewController:nil
                                userDidEarnRewardHandler:^{

                                  GADAdReward *reward =
                                      self.rewardedInterstitialAd.adReward;
                                  // TODO: Reward the user.
                                }];
}
