title: How can I check the 5 ccspirits have passed through the screen on iPhone?
body: <p>I have many ccspirits in NSMutableArray, and I am taking them from these NSMutableArray, and sending to as method as a sender, and following</p>
  
  <pre><code>   id actionMove2 = [CCMoveTo actionWithDuration:6 position:ccp(40, 520)];
     id actionMoveDone2 = [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)];
  
    [sender runAction:[CCSequence actions:actionMove2, actionMoveDone2, nil]];
  </code></pre>
  
  <p>now I want to calculate that five ccspirit has passed through the screen because the user is draging and droping many items so these will not be included, how can I do ?</p>
