iAd shows but doesn't react to taps

Question

I am developing a game with SpriteKit in Swift. I want to show the iAd on top on my game scene.

iAd shows, but when I tap it, it has no reaction. Nothing happens.

Here is my code:

import UIKit

import SpriteKit import iAd

class GameViewController: UIViewController, ADBannerViewDelegate, BackToMenuDelegate {

var bannerView:ADBannerView =  ADBannerView()
var currentLevel:Int!

override func viewDidLoad() {
    super.viewDidLoad()
    // Configure the view.
    let skView = self.view as SKView
    skView.multipleTouchEnabled = false

    /* Set the scale mode to scale to fit the window */
    let gameScene = GameScene(size:skView.bounds.size)
    gameScene.scaleMode = .AspectFill
    gameScene.currentLevel = currentLevel
    gameScene.gameViewController = self
    skView.presentScene(gameScene)
}

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
}

override func shouldAutorotate() -> Bool {
    return false
}

override func supportedInterfaceOrientations() -> Int {
    if UIDevice.currentDevice().userInterfaceIdiom == .Phone {
        return Int(UIInterfaceOrientationMask.AllButUpsideDown.rawValue)
    } else {
        return Int(UIInterfaceOrientationMask.All.rawValue)
    }
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Release any cached data, images, etc that aren't in use.
}

override func prefersStatusBarHidden() -> Bool {
    return true
}

func bannerViewDidLoadAd(banner: ADBannerView!) {
    bannerView.hidden = false
}
func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {
    return willLeave
}
func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
    bannerView.hidden = true
}
func loadAds(){
    bannerView.delegate = self
    bannerView.hidden = true

    var adRect = CGRectZero
    let contentFrame = self.view.bounds
    adRect.size = bannerView.sizeThatFits(contentFrame.size)
    adRect.origin.y = 0
    bannerView.frame = adRect

    self.view.addSubview(bannerView)
}
func backToMenu(){
    self.navigationController!.popToRootViewControllerAnimated(true)
    let skView = self.view as SKView
    skView.presentScene(nil)
}

func shareScore(score:Int){
    var objectsToShare = [AnyObject]()
    let textToShare = "I just got \(score) points in BlockCracker! Check out this App!"
    objectsToShare.append(textToShare)
    if let myWebsite = NSURL(string: "http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=611627312&mt=8")
    {
        objectsToShare.append(myWebsite)
    }
    let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
    activityVC.excludedActivityTypes = [UIActivityTypeAirDrop, UIActivityTypeAddToReadingList, UIActivityTypeAddToReadingList,UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard,UIActivityTypePostToFlickr,UIActivityTypePostToVimeo,UIActivityTypeMail,UIActivityTypeMessage]
    self.presentViewController(activityVC, animated: true, completion: nil)

}
override func viewDidDisappear(animated: Bool) {
    super.viewDidDisappear(animated)

}

}

Finally found the problem. Just here in func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool { return willLeave } which willLeave default false! Just change to return true value.Now everything goes fine!
