title: Push a Viewcontroller in a cocos2D scene
body: <p>I have an app. This app combines UIKit and Cocos2D. 
  I have a UIKit menu with a button that calls a cocos2D game. It works fine.</p>
  
  <p>Now, I would like to remove the cocos scene to push the UIKit menu. (Game is over, it's necessary to go on the menu view)</p>
  
  <p>I tried </p>
  
  <pre><code>[[CCDirector sharedDirector] end];
  [[CCDirector sharedDirector].openGLView removeFromSuperview];
  </code></pre>
  
  <p>It doesn't work. I don't know how to do.</p>
  
  <p>Thanks for your help !</p>
