title: tvos How to let the user move focus more freely?
body: <p>I am constructing a card-game (for tvos) where the user should be able to  remove cards from a board.
  At the end of the game only a few cards may be left at the board, and they might e.g. be arranged as the buttons in the picture below.</p>
  
  <p>How can I let the user move focus from say button 1 to <strong>button 0 or 2?</strong></p>
  
  <p>In <em>un-accepted</em> answers to a similar question at SO, it was suggested that one should use an <code>UIFocusGuide</code>. I do not think that answer is applicable to my problem, because in that approach one must tell the focusGuide the <code>preferredFocusedView</code> in advance (e.g. before the user swipes in siri-remote)! In my case, the preferred next focus depends on the swipe direction, e.g. the  <code>focusHeading</code>.</p>
