在范围内找不到类型“GADInterstitial”？

Question

我刚刚将 Google 移动广告 SDK 升级到 8.0 版，但出现此错误：

在范围内找不到类型“GADInterstitial”

我也将此代码添加到 AppDelegate：

GADMobileAds.sharedInstance().start(completionHandler: nil)

在我升级到 8.0 版之前，Google 移动广告 SDK 运行良好

注意：我还在我的应用中使用 Firebase 框架。

这里是 Admob Interstitial 的代码，只能复制粘贴 我刚刚将 Google 移动广告 SDK 升级到 8.0 版

import GoogleMobileAds

class ViewController: UIViewController,GADFullScreenContentDelegate{
    
private var interstitial: GADInterstitialAd?
    
override func viewDidLoad() {
    super.viewDidLoad()
    
    let request = GADRequest()
        GADInterstitialAd.load(withAdUnitID:"ca-app-pub-3940256099942544/4411468910",request: request,
        completionHandler: { [self] ad, error in
          if let error = error {
             return
             }
             interstitial = ad
             interstitial?.fullScreenContentDelegate = self
            }
        )
}

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

 func adDidPresentFullScreenContent(_ ad: GADFullScreenPresentingAd) {
   print("Ad did present full screen content.")
 }

 func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
   print("Ad did dismiss full screen content.")
 }   

@IBAction func AddAction(_ sender: UIButton) {        
    if interstitial != nil {
        interstitial.present(fromRootViewController: self)
      } else {
        print("Ad wasn't ready")
      }
}         

}

Google 已在未告知任何人的情况下更新了 SDK。 查看 Admob 上的新指南以添加插页式广告。 本质上，GADInterstitial 已更改为 GADInterterstitialAd，您也必须使用不同的委托。

感谢 Google。

Answer 3

Google 移动广告 SDK 8.0 的 API 接口发生了巨大变化。请参考谷歌的official document for Interstitial。为了完整起见，这里是对 8.0 之前的 legacy API 的引用。

主要变化是委托和广告类：

old	new
GADInterstitialDelegate	GADFullScreenContentDelegate
GADInterstitial	GADInterstitialAd

而不是以传统方式初始化广告：

interstitial = GADInterstitial(adUnitID: "ca-app-pub-3940256099942544/4411468910")
let request = GADRequest()
interstitial.load(request)

它现在通过以下方式初始化

let request = GADRequest()
GADInterstitialAd.load(withAdUnitID:"ca-app-pub-3940256099942544/4411468910",
                            request: request,
                  completionHandler: { [self] ad, error in
                    if let error = error {
                      print("Failed to load interstitial ad with error: \(error.localizedDescription)")
                      return
                    }
                    interstitial = ad
                    interstitial?.delegate = self
                  }

还有新的 GADFullScreenContentDelegate 方法：

/// 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 presented full screen content.
func adDidPresentFullScreenContent(_ ad: GADFullScreenPresentingAd) {
  print("Ad did 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.")
}

请注意，不再有 interstitialDidReceiveAd 方法。相反，您要么在 GADInterstitialAd.load() 完成回调中开始展示广告，要么在稍后阶段展示广告（如果它已初始化）：

if interstitial != nil {
  interstitial.present(fromRootViewController: self)
} else {
  print("Ad wasn't ready")
}
