添加AdMob间质Swift时的错误

Question

我正在尝试添加AdMob中间层，但我不知道如何添加。我在YouTube上尝试了一个教程，但我收到了两个错误。

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()
    }
}

Answer 1

添加此代码

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

var request = GADRequest()

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

return ad
}
