Question

这是与错误关联的代码的一部分。我的应用程序构建成功，但是崩溃了，我收到了：

“线程1：异常：”-[（（name）.ViewController playVideoAd：]：无法识别的选择器已发送到实例0x7f878ce0d470“）

var rewardedAd: GADRewardedAd?
   override func loadView() {

       super.loadView()
     rewardedAd = GADRewardedAd(adUnitID: "ca-app-pub-3940256099942544/1712485313")
       rewardedAd?.load(GADRequest()) { error in
        if error != nil {
              // Handle ad failed to load case.
            } else {
              // Ad successfully loaded.
            }

        do {

            func playvideoad(_ sender: UIButton) {
        if self.rewardedAd?.isReady == true {
            self.rewardedAd?.present(fromRootViewController: self, delegate:self)
              }
           }
       }
    }
}

Answer 1

从IBAction之外获取loadView

var rewardedAd: GADRewardedAd?
   override func loadView() {

       super.loadView()
     rewardedAd = GADRewardedAd(adUnitID: "ca-app-pub-3940256099942544/1712485313")
       rewardedAd?.load(GADRequest()) { error in
           if error != nil {
              // Handle ad failed to load case.
            } else {
              // Ad successfully loaded.
            } 
       }
}

@IBAction func playVideoAd(_ sender: UIButton) {
   if self.rewardedAd?.isReady == true {
     self.rewardedAd?.present(fromRootViewController: self, delegate:self)
   }
}

Answer 2

好像是错字？在调用playVideoAd函数时，您的函数名为playvideoad。加上如何在另一个函数中初始化一个功能块？
