在離開場景時刪除UIGestures

我在我的遊戲中遇到了UIGestures問題在遊戲場景中，它們完美無缺，但是當我移動到另一個場景時，如果我使用它們（刷卡）而不是崩潰。在離開場景時刪除UIGestures

我知道我必須在Gamescene文件中使用willmovefromview方法，但在這已經工作2天，仍然沒有工作..

這裏是我的視圖 - 控制文件（見註釋的手勢功能和手勢識別）

import UIKit 
import SpriteKit 
import AVFoundation 


class GameViewController: UIViewController, UITextFieldDelegate{ 

//gesture functions 
func swipedRight(sender: UISwipeGestureRecognizer){ 
    let skView = view as SKView 
    let gameScene = skView.scene as GameScene 
    gameScene.swipedRight1(sender) 
} 
func swipedLeft(sender: UISwipeGestureRecognizer){ 
    let skView = view as SKView 
    let gameScene = skView.scene as GameScene 
    gameScene.swipedLeft1(sender) 
} 
func swipedDown(sender: UISwipeGestureRecognizer){ 
    let skView = view as SKView 
    let gameScene = skView.scene as GameScene 
    gameScene.swipedDown1(sender) 
} 
func swipedUp(sender: UISwipeGestureRecognizer){ 
    let skView = view as SKView 
    let gameScene = skView.scene as GameScene 
    gameScene.swipedUp1(sender) 
} 


override func viewDidLoad() { 
    super.viewDidLoad() 

    let skView = view as SKView 
    skView.multipleTouchEnabled = false 
    scene = GameMenuScene(size: skView.bounds.size) 
    //scene.scaleMode = SKSceneScaleMode.ResizeFill 
    skView.showsFPS = true 
    skView.showsNodeCount = true 
    skView.presentScene(scene) 

//Gesture recognizers 
    let swipeRight:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector("swipedRight:")) 
    swipeRight.direction = .Right 
    view.addGestureRecognizer(swipeRight) 

    let swipeLeft:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector("swipedLeft:")) 
    swipeLeft.direction = .Left 
    view.addGestureRecognizer(swipeLeft) 

    let swipeUp:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector("swipedUp:")) 
    swipeUp.direction = .Up 
    view.addGestureRecognizer(swipeUp) 

    let swipeDown:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: Selector("swipedDown:")) 
    swipeDown.direction = .Down 
    view.addGestureRecognizer(swipeDown)  
} 

override func viewDidLayoutSubviews() { 
} 


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

}

PS：我的應用程序開始在menuscene，並揮筆只能是活躍在gamescene，所以我覺得我必須使用didmovetoview方法爲好。

，這裏是我的gamescene文件didmovetoview方法和willmovefromview方法：

override func didMoveToView(view: SKView) { 

} 
override func willMoveFromView(view: SKView) { 

}

誰來幫幫我？在此先感謝

override func willMoveFromView(view: SKView) { 
    for recognizer in self.view.gestureRecognizers! { 
     self.view.removeGestureRecognizer(recognizer) 
    } 
}

錯誤：SKView？沒有名爲'gestureRecognizers'的成員 – DNC 2014-12-05 00:41:10

使用您添加了手勢識別器的相同視圖。 – Mundi 2014-12-05 00:52:15

你是什麼意思？我在我的視圖控制器中添加了手勢識別器，您可以在我的帖子中看到代碼。 – DNC 2014-12-05 01:00:21

-1

self.view.gestureRecognizers=nil;

這對我的作品。
