title: Hide controls in AVPlayerViewController -- only at start
body: <p>If you set AVPlayerViewController.showsPlaybackControls to false, the controls will not show at all. Even if you tap the screen.</p>
  
  <p>I want the controls to start out hidden, but still be able to summon them by tapping. If I set the mentioned property to true, they start out visible. (Yes they fade after a few seconds.) Is there a way to start hidden, but still be accessible?</p>
