Question

我目前有一个为我的视图控制器运行的插页式广告。问题是当广告未准备好时，我的应用程序会因错误而崩溃。如果有人可以帮助我解决以下问题，我将不胜感激！谢谢

视图控制器：问题是当广告未准备好时，应用会因错误而崩溃。

class JournalViewController: UIViewController, GADFullScreenContentDelegate {
    
    var interstitial: GADInterstitialAd!   
 
    override func viewDidLoad() {

        super.viewDidLoad()

        let request = GADRequest()
        GADInterstitialAd.load(withAdUnitID:"id ...",
                                      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?.fullScreenContentDelegate = self
                            }
          )
                
       let randomTime = Double(arc4random() + 20).truncatingRemainder(dividingBy: 60.0)
        Timer.scheduledTimer(timeInterval: randomTime, target: self, selector: #selector(ViewController.CreateAd), userInfo: nil, repeats: false)
        
    }
    @objc func CreateAd() -> GADInterstitialAd {
        
        if interstitial != nil {
                    interstitial.present(fromRootViewController: self)
                    let randomTime = Double(arc4random() + 20).truncatingRemainder(dividingBy: 60.0)
                    Timer.scheduledTimer(timeInterval: randomTime, target: self, selector: #selector(ViewController.CreateAd), userInfo: nil, repeats: false)
        } else {
            print("Ad not ready") // Thread 1: EXC_BAD_ACCESS (code=2, address=0x7ffee788bff8)
            interstitial = CreateAd()
        }
        return interstitial
            }

此外，如果有人有时间也看看这个。我想让广告多次投放。我知道插页式广告不允许这样做，为了解决这个问题，我实现了这个功能，但它不起作用。这是错误的吗？

    func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
        
        interstitial = CreateAd()
        
    }

您不应从 CreateAd() 返回广告，应在调用 GADInterstitialAd.load(..) 的 completionHandler 时设置广告。

这应该是您的 createAd 函数（不返回任何内容）：

var interstitial: GADInterstitialAd?


func createAd() {
    GADInterstitialAd.load(withAdUnitID:"id ...",
                                  request: GADRequest(),
                        completionHandler: { ad, error in
                          if let error = error {
                            print("Failed to load interstitial ad with error: \(error.localizedDescription)")
                            return
                          }
                            interstitial = ad
                            interstitial?.fullScreenContentDelegate = self
                        }
      )
}

然后随时展示它，并在广告关闭后再次调用 createAd()
