为 SDK v8 做准备

Google 移动广告 SDK 版本 8.0.0 引入了一些重大更改，同时重命名和移除了一些 API。

关于全屏广告格式 API 的更新

从版本 8.0.0 开始，插页式广告和激励广告会共用常规的全屏广告样式，以提高一致性。这些新版全屏广告 API 与版本 7 的全屏广告 API 有两大主要区别：

1. 静态类方法 load。

   之前加载/展示全屏广告的方法如下：

   1. 创建广告对象实例并保留对该实例的引用。
   2. 分配一个处理加载和显示回调的代理。
   3. 加载广告。
   4. 使用 isReady 检查广告是否已加载。
   5. 展示广告。

   在版本 8 中，加载/展示广告的方法略有变化。加载回调不再是代理所需处理的工作。相反，这些回调会作为完成处理程序传入 load 方法：

   1. 针对广告类调用静态加载方法，并提供加载完成处理程序。
   2. 在加载完成回调中，保留对返回的已加载广告的引用。
   3. 分配一个处理显示回调的代理。
   4. 展示广告。

   新方法具有以下优点：

   • 您将不会再有对未加载的广告的引用。
   • 广告加载时，您无需保留广告对象。

2. 广告事件一致。

   事件类型	现有 API	v8 中的 API
   加载事件	GADInterstitialDelegate 或者 GADRewardedAdDelegate	GADInterstitialAdLoadCompletionHandler 或者 GADRewardedAdLoadCompletionHandler
   展示事件		GADFullScreenContentDelegate

   之前，要监听任何广告事件，您都要注册一个对插页式广告的代理属性实现 GADInterstitialDelegate 协议的类，或者注册一个对激励广告的代理属性实现 GADRewardedAdDelegate 协议的类，具体哪个类取决于您使用的广告格式。同一代理具有与广告加载和展示生命周期都相关的方法。

   对于版本 8，加载和展示事件可以区分开来。现在，您可以在展示广告之前随时注册 GADFullScreenContentDelegate，而无需在加载广告前先设置单一代理。各种广告格式特有的广告加载事件将转变为加载方法中传递的单个加载完成处理程序。

插页式广告

加载广告

以下代码段展示了如何加载插页式广告，以及如何在广告成功加载或加载失败时监听事件。

Swift

import GoogleMobileAds
import UIKit

class ViewController: UIViewController, GADInterstitialDelegate {

  var interstitial: GADInterstitial!

  override func viewDidLoad() {
    super.viewDidLoad()

    interstitial.delegate = self
    let request = GADRequest()
    interstitial.load(request)
  }

  /// Tells the delegate an ad request succeeded.
  func interstitialDidReceiveAd(_ ad: GADInterstitial) {
    print("Interstitial ad loaded.")
  }

  /// Tells the delegate an ad request failed.
  func interstitial(_ ad: GADInterstitial, didFailToReceiveAdWithError error: GADRequestError) {
    print("Interstitial ad failed to load with error: \(error.localizedDescription)")
  }
}

展示广告和处理奖励

激励广告要求您在用户获得奖励时处理该事件。借助版本 7 中的 GADRewardedAd API，您可以将 rewardedAd:userDidEarnReward: 作为 GADRewardedAdDelegate 协议的一部分实现。对于版本 8，您需要实现 GADUserDidEarnRewardHandler 才能展示广告。

v7

Swift

func showRewardedAd() {
  ...
  if rewardedAd.isReady {
    rewardedAd.present(fromRootViewController: self delegate:self)
  } else {
    print("Ad wasn't ready")
  }
}

/// Tells the delegate that the user earned a reward.
func rewardedAd(_ rewardedAd: GADRewardedAd, userDidEarnReward: GADAdReward) {
  // TODO: Reward the user.
}

Objective-C

- (void)showRewardedAd: {
  ...
  if (self.rewardedAd.isReady) {
    [self.rewardedAd presentFromRootViewController:self delegate:self];
  } else {
    NSLog(@"Ad wasn't ready");
  }
}

/// Tells the delegate that the user earned a reward.
- (void)rewardedAd:(GADRewardedAd *)rewardedAd userDidEarnReward:(GADAdReward *)reward {
  // TODO: Reward the user.
}

v8

Swift

func showRewardedAd() {
  ...
  if let ad = rewardedAd {
      ad.present(fromRootViewController: self,
               userDidEarnRewardHandler: {
                 let reward = ad.adReward
                 // TODO: Reward the user.
               }
      )
  } else {
    print("Ad wasn't ready")
  }
}

Objective-C

- (void)showRewardedAd: {
  ...
  if (self.rewardedAd) {
    [self.rewardedAd presentFromRootViewController:self
                          userDidEarnRewardHandler:^ {
      GADAdReward *reward = self.rewardedAd.adReward;
      // TODO: Reward the user.
    }];
  } else {
    NSLog(@"Ad wasn't ready");
  }
}

展示广告事件

借助 GADRewardedAd API，您可以将 GADRewardedAdDelegate 传递给展示广告的方法。借助 GADRewardedAd API，您可以将 GADFullscreenContentDelegate 设为广告的属性，然后再展示广告。

v7

  ...

    rewardedAd.present(fromRootViewController: self delegate:self)

}
/// Tells the delegate that the rewarded ad failed to present.

移除旧版 GADRewardedBasedVideoAd API

新版 GADRewardedAd API 于 2019 年 3 月首次推出，在之后的 18 个月里一直是首选激励广告 API。与旧版 GADRewardedBasedVideoAd API 相比，新版 API 添加了多项改进，其中包括能够一次加载多个激励广告。

SDK 版本 8.0.0 中移除了该旧版 GADRewardedBasedVideoAd API。

弃用智能横幅广告，改用自适应横幅广告

弃用了智能横幅广告，现在使用的是自适应横幅广告。自适应横幅广告的效果更好，可以让您更灵活地设置广告宽度。如果您希望继续使用全宽横幅广告，仍然可以通过自适应横幅广告实现，如以下代码段所示：

Swift

class ViewController: UIViewController {

  override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    // Note: The safe area is not known until viewWillAppear.
    let adSize = getFullWidthAdaptiveAdSize()
  }

  func getFullWidthAdaptiveAdSize() -> GADAdSize {
    // Here safe area is taken into account, hence the view frame is used after the
    // view has been laid out.
    let frame = { () -> CGRect in
      if #available(iOS 11.0, *) {
        return view.frame.inset(by: view.safeAreaInsets)
      } else {
        return view.frame
      }
    }()
    return GADCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth(frame.size.width)
  }
}

Objective-C

@implementation ViewController

- (void)viewDidAppear:(BOOL)animated {
  [super viewDidAppear:animated];
  // Note: The safe area is not known until viewWillAppear.
  GADAdSize adSize = [self getFullWidthAdaptiveAdSize];
}

- (GADAdSize)getFullWidthAdaptiveAdSize {
  CGRect frame = self.view.frame;
  // Here safe area is taken into account, hence the view frame is used after
  // the view has been laid out.
  if (@available(iOS 11.0, *)) {
    frame = UIEdgeInsetsInsetRect(self.view.frame, self.view.safeAreaInsets);
  }
  return GADCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth(frame.size.width);
}

@end

移除退出应用回调函数

移除了所有广告格式的 willLeaveApplication 回调函数，改为使用 applicationDidEnterBackground: 和 sceneDidEnterBackground: 方法。如果使用操作系统级 API，无论用户是否因广告互动而打开您的应用，只要他们退出应用，您都会收到通知。

请注意，千万不要将 willLeaveApplication 回调函数用作广告点击处理程序，如果依赖此类回调函数来报告点击，将无法生成准确的指标。例如，用户点击“广告选择”图标时会启动外部浏览器，这时系统会调用该回调函数，但不会将其计为一次点击。

重命名类

下表列出了版本 8 中已更改或移除的具体类名称。总结如下：

• 与 GADUnifiedNativeAd 相关的所有类均已重命名为 GADNativeAd。
