title: Moving between GameScene and ViewController Swift
body: <p>I want to move from my GameScene to ViewController, when I touch an Image and back to GameScene when I touch an UIButton.
  It worked from ViewController to GameScene, because it is UIButton.</p>
  
  <p>I have done it like this: </p>
  
  <pre><code>@IBAction func playbut(sender: UIButton) {
      var scene = GameScene(size: CGSize())
      let skView = self.view as! SKView!
      skView.ignoresSiblingOrder = true
      scene.scaleMode = .ResizeFill
      scene.size = skView.bounds.size
      skView.presentScene(scene)
  }
  </code></pre>
  
  <p>But I don't know what code to write to go back to ViewController, when I touch that image, which is on GameScene.</p>
  
  <p>What should I write to GameScene?</p>
  
  <p>Thanks</p>
