错误无法将UIView类型的值转换为SKview [英] Error Could not cast value of type UIView to SKview

问题描述

自从我添加iAd以来，我一直收到此错误. 无法将类型'UIView'(0x196afa530)的值强制转换为'SKView'(0x19685f560)."

Ever since i added in iAds i keep getting this error. "could not cast value of type 'UIView' (0x196afa530) to 'SKView' (0x19685f560)."

这是失败的代码，而底部的代码是我的视图控制器代码. 我认为，这也与iAd的这段代码有关.

this is the code that fails and the code on the bottom is my inter view controller code.. which is not much. i think at also has something to do with this code for iAds.

    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:

All ViewController code:

  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
    }
  }

}

            vc.presentViewController(viewController, animated: true, completion: nil)

推荐答案

我也发生了同样的事情.您要做的就是将所有iAd代码转移到GameScene.swift中，并将self更改为self.view！.window！.rootViewController！哪里有错误.

The same thing happened to me. All you have to do is transfer all your iAd code to your GameScene.swift and change self into self.view!.window!.rootViewController! wherever there is an error.
