添加AdMob插页式广告时出现错误Swift

Question

我正在尝试添加AdMob插页式广告，但我不知道该如何处理。我在YouTube上尝试过一个教程，但收到2个错误。

var interstitial: GADInterstitial! 

    override func viewDidLoad() { 
    super.viewDidLoad() 

    self.interstitial = self.createAndLoadAd() 

    func createAndLoadAd() -> GADInterstitial { 
    var ad = GADInterstitial() 
    ad.adUnitID = "myInterstitialID" 

    var request = GADRequest() 

    request.testDevices = ["2077ef9a63d2b398840261c8221a0c9b"] 
    ad.loadRequest(request) 

    return ad 
} 

@IBAction func adButton(sender: AnyObject) { 
    if (self.interstitial.isReady) 
    { 
     self.interstitial.presentFromRootViewController(self) 
     self.interstitial = self.createAndLoadAd() 
    } 
}

添加以下代码

func createAndLoadAd() -> GADInterstitial { 
var ad = GADInterstitial(adUnitID: "ca-app-pub-3940256099942544/4411468910") 

var request = GADRequest() 

request.testDevices = ["2077ef9a63d2b398840261c8221a0c9b"] 
ad.loadRequest(request) 

return ad 
}
