【问题描述】：

我正在使用 Swift 在我的应用中实现插页式广告。我设法让它显示插页式广告，但没有关闭“X”按钮来摆脱广告。这是为什么呢？

【解决方案1】：

我也找不到为什么内置框架不提供关闭按钮的答案，但我最终使用了以下解决方案。

//iAD interstitial definition with custom placeHolderView and close button
//you do not need to add anything to interface builder. All is done with code

var interstitial:ADInterstitialAd!
var placeHolderView:UIView!
var closeButton:UIButton!

//Full Implemantation of iAD interstitial and delegate methods

 func cycleInterstitial(){
 // create a new interstitial. We set the delegate so that we can be notified 
    interstitial = ADInterstitialAd()
    interstitial.delegate = self;
}

func presentInterlude(){
    // If the interstitial managed to load, then we'll present it now.
    if (interstitial.loaded) {

        placeHolderView = UIView(frame: self.view.frame)
        self.view.addSubview(placeHolderView)

        closeButton = UIButton(frame: CGRect(x: 270, y:  25, width: 25, height: 25))
       //add a cross shaped graphics into your project to use as close button
        closeButton.setBackgroundImage(UIImage(named: "cross"), forState: UIControlState.Normal)
        closeButton.addTarget(self, action: Selector("close"), forControlEvents: UIControlEvents.TouchDown)
        self.view.addSubview(closeButton)


        interstitial.presentInView(placeHolderView)
    }
}

// iAd Delegate Mehtods

// When this method is invoked, the application should remove the view from the screen and tear it down.
// The content will be unloaded shortly after this method is called and no new content will be loaded in that view.
// This may occur either when the user dismisses the interstitial view via the dismiss button or
// if the content in the view has expired.

func interstitialAdDidUnload(interstitialAd: ADInterstitialAd!){
    placeHolderView.removeFromSuperview()
    closeButton.removeFromSuperview()
    interstitial = nil

    cycleInterstitial()
}


func interstitialAdActionDidFinish(_interstitialAd: ADInterstitialAd!){
    placeHolderView.removeFromSuperview()
    closeButton.removeFromSuperview()
    interstitial = nil

    println("called just before dismissing - action finished")

}

// This method will be invoked when an error has occurred attempting to get advertisement content.
// The ADError enum lists the possible error codes.
func interstitialAd(interstitialAd: ADInterstitialAd!,
    didFailWithError error: NSError!){
        cycleInterstitial()
}


//Load iAd interstitial
func dislayiAdInterstitial() {
    //iAd interstitial
    presentInterlude()
}


func close() {
    placeHolderView.removeFromSuperview()
    closeButton.removeFromSuperview()
    interstitial = nil

}

【解决方案2】：

使用 interstitial=InterstitialAd() 会导致我和你一样的问题。

但是，如果您在 AppDelegate 的应用程序函数中包含以下代码：

UIViewController.prepareInterstitialAds()

然后，您可以使用以下方法生成插页式广告：

viewController.requestInterstitialAdPresentation()

不过，我不确定如何获取回调。

【解决方案3】：

iOS 9.2.1，Xcode 7.2.1，启用 ARC

请阅读我的帖子：

我仍然使用presentFromViewController: 方法。

希望这会有所帮助！干杯。
