Xcode 错误无法将UIView类型的值强制转换为SKview

自从我加入iAds后，我就一直犯这个错误。无法将“UIView”（0x196afa530）类型的值强制转换为“SKView”（0x19685f560）

这是失败的代码，底部的代码是我的视图间控制器代码。。这并不多。 我认为at也与iAds的代码有关

    var interstitialAdView: UIView = UIView()

代码：

 override func viewWillLayoutSubviews() {
    super.viewWillLayoutSubviews()
    if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene {
         let skView = self.view as! SKView
        self.canDisplayBannerAds = true
            skView.showsFPS = false
            skView.showsNodeCount = false
            skView.ignoresSiblingOrder = true
            scene.scaleMode = .AspectFill
            let scene: SKScene = GameScene(size: skView.bounds.size)
            skView.presentScene(scene)
       }
    }

所有ViewController代码：

  import UIKit
  import StoreKit
  import SpriteKit
  import GameKit
  import iAd

 extension SKNode {
class func unarchiveFromFile(file : String) -> SKNode? {
    if let path = NSBundle.mainBundle().pathForResource(file, ofType: "sks") {
        var sceneData = NSData(contentsOfFile: path, options: .DataReadingMappedIfSafe, error: nil)!
        var archiver = NSKeyedUnarchiver(forReadingWithData: sceneData)

        archiver.setClass(self.classForKeyedUnarchiver(), forClassName: "SKScene")
        let scene = archiver.decodeObjectForKey(NSKeyedArchiveRootObjectKey) as! GameScene
        archiver.finishDecoding()
        return scene
    } else {
        return nil
    }
  }

}

    var localPlayer = GKLocalPlayer()

    localPlayer.authenticateHandler = {(viewController, error) -> Void in

        if (viewController != nil) {
            let vc: UIViewController = self.view!.window!.rootViewController!
            vc.presentViewController(viewController, animated: true, completion: nil)
        }

        else {

同样的事情也发生在我身上。你所要做的就是将你所有的iAd代码转移到你的GameSecene.swift并将self改为self.view！。窗口！。rootViewController！无论哪里出错。
