title: NSMutableArray check with IndexPath
body: <p>I store touched Items from my UICollectionView into a NSMutableArray, then reloadData.</p>
  
  <p>My question is, how can I check if IndexPath.row is equal to any of my NSMutableArray objects?</p>
  
  <p>I can do something like:</p>
  
  <pre><code>if(indexPath.row == [myMutableArray objectAtIndex:0])
  </code></pre>
  
  <p>But in this case, it will check only for first object from my NSMutableArray, I want to check all available objects if any of them are == to indexPath.row</p>
  
  <p>I'm a beginner, and trying to figure out.</p>
  
  <p>Thanks.</p>
