title: Using CCSchedulers/CCTimers in Cocos2d Project
body: <p>I have a GameController object, which is meant to manage stuff like the scores.</p>
  
  <p>The score is based on how long the user has played, so I want to increase the score by one every 2 seconds. So my GameController is a subclass of NSObject, and I'm trying to use a CCTimer or CCScheduler (CCTimer seems to be depreciated?) But using this line, the method never fires:</p>
  
  <pre><code>[[CCScheduler sharedScheduler] scheduleSelector:@selector(updateNaturalScore:) forTarget:self interval:1 paused:NO];
  </code></pre>
  
  <p>Do I have to user this in a Cocos2d object? If so which one? Or should it work in an NSObject subclass?</p>
