swift - 关闭插页式广告后呈现新的 ViewController - Swift 4

Question

一旦用户关闭插页式广告，我就会尝试让此按钮转到新的 ViewController。 Segue 代码可以在没有广告代码的情况下工作，广告代码也可以在没有 Segue 代码的情况下工作。无论哪个先放，都会先发生，但我不知道如何让它们一起工作。您会注意到我尝试将 self.present... 移动到不同的地方，但没有成功(请参阅注释行)。

@IBAction func adButton(_ sender: UIButton) {

    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let myVC = storyboard.instantiateViewController(withIdentifier: "newVC")
    //self.present(myVC, animated: true, completion: nil)

    if (interstitial.isReady) {
        interstitial.present(fromRootViewController: self)
        interstitial = createAd()
        //self.present(myVC, animated: true, completion: nil)
    }
    self.present(myVC, animated: true, completion: nil)
}

interstitial 对象具有一个委托(delegate) (GADInterstitialDelegate) 协议(protocol)，您可以遵守该协议(protocol)，以便在广告被关闭时收到通知。有多种处理广告状态的委托(delegate)方法，您可以在文档中查看这些方法。

class ViewController:UIViewController, GADInterstitialDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        interstitial = GADInterstitial(adUnitID: "ca-app-pub-3940256099942544/4411468910")
        interstitial.delegate = self
        let request = GADRequest()
        interstitial.load(request)
    }

    @IBAction func adButton(_ sender: UIButton) {

        if (interstitial.isReady) {
            interstitial.present(fromRootViewController: self)
        } else {
           self.present(myVC, animated: true, completion: nil)
       }
    }

    //Tells the delegate the interstitial is to be animated off the screen.
    func interstitialWillDismissScreen(_ ad: GADInterstitial) {
        print("interstitialWillDismissScreen")
    }

    //Tells the delegate the interstitial had been animated off the screen.
    func interstitialDidDismissScreen(_ ad: GADInterstitial) {
        print("interstitialDidDismissScreen")
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let myVC = storyboard.instantiateViewController(withIdentifier: "newVC")
        self.present(myVC, animated: true, completion: nil)
    }
}
