title: iPhone SDK: how to switch to previous view when video playback is over?
body: <p>There is an application which uses several view controllers. In one of them there is a button which switches to a new view, and there, in viewDidLoad method, I launch a video playback. But when it's stopped, an empty view pops up instead of the previous view I'm working with. </p>
  
  <p>What is a proper way to switch back to the previous view automatically? I've read about MPMoviePlayerPlaybackDidFinishNotification so I can use it.</p>
  
  <p>It's a navigation-based application.</p>
