title: SpriteKit- the right way to multitask
body: <p>I tried to search everywhere in the code:Explained documentry what it does when going to background, or if it is even paused sometime, but to no avail- can someone direct me in the way of what is recommended to do when going to background in sprite kit enabled game?</p>
  
  <p>Should I just call <code>scene.paused = YES</code>, or how can I confirm that no drawing occurs in background so I can avoid termination by iOS which won't allow me that?</p>
  
  <p>Thanks!</p>
