title: UICollectionView cell: is it safe to bring cell.selectedBackgroundView to front?
body: <p>I am just starting to implement a multiselect UICollectionView. Would the below be considered "safe" code (since i assume theres some reason it is called BackgroundView instead of AccessoryView or such) ? I had the idea to save some effort, i intend to keep track of the selected items at the indexpath for further use via an array. </p>
  
  <pre><code>-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath 
  {
   //....
  
   cell.selectedBackgroundView = someView_With_A_Checkmark_Image;
   [cell bringSubviewToFront:cell.selectedBackgroundView];
  
   //...
  return cell;
  
  }
  </code></pre>
