title: Cocos3D handleTouch:ofType: not recognized
body: <p>When I try to activate touch move support by uncommenting following function (as recommended in documentation):</p>
  
  <pre><code>///*
  -(void) ccTouchMoved: (UITouch *)touch withEvent: (UIEvent *)event {
      [self handleTouch: touch ofType: kCCTouchMoved];
  }
   //*/
  </code></pre>
  
  <p>I get compilation error:</p>
  
  <pre><code>No visible @interface for 'CC3HelloWorldLayer' declares the selector 'handleTouch:ofType:'
  </code></pre>

  <p>This function is declared in CCLayer.h from which CC3layer inherits.</p>
  
  <p><strong>What is the cause of that strange error?</strong></p>
