更改GameViewController（SpriteKit Swift）中变量的值

Question

我在类GameViewController中创建了一个UIScrollView，其中Subviews是场景。当用户进入特定场景并按下特定按钮时，ScrollView必须停止滚动。
我该怎么做？代码

例子：

import SpriteKit 
class GameViewController: UIViewController { 
    @IBOutlet weak var scrollView: UIScrollView! 
    ... 
} 
class GameScene: SKScene { 
    //Here we have button and if we will push it 
    //then scrollView.scrollEnabled must be false in class GameViewController. 

Answer 1

尽量让新类与此代码

class Data { 
struct gameScene { 
    static var ButtonPressed:Bool = false 
} 
} 

然后，让你的代码的一些变化

var gameScene: GameScene! 

    override func viewDidAppear(animated: Bool) { 
     gameScene = GameScene() 
     } 

     @IBAction func butPressed(sender: UIButton) { 
     Data.gameScene.buttonPressed = true 
    println("Pressed from GameViewController") 
} 

    override func update(currentTime: CFTimeInterval) { 

     if (Data.gameScene.buttonPressed == true) { 

       println("Pressed from GameScene") 

       Data.gameScene.buttonPressed = false 
      } 
      } 

可以调用这个变量使用此代码在您项目中的任何地方

    Data.gameScene.buttonPressed
