title: Making the first cell of a UICollectionView focused on tvOS
body: <p>OK, if I have a <code>UIViewController</code> I can make a view focused on tvOS if I use this `preferredFocusedView but what about making the first cell of a UICollectionView focused? How do I do that?</p>
  
  <p>I have tried to create a <code>UICollectionViewCell</code> subclass and have the method </p>
  
  <pre><code>- (UIView *)preferredFocusedView {
     return ([self ifThisIsTheFirstCell]) ? self : nil;
  }
  </code></pre>
  
  <p>without success.</p>
  
  <p>Is there a way to do that?</p>
