How do I intercept tapping of the done button in AVPlayerViewController?

Question

I created an `AVPlayerViewController` and an attached `AVPlayer` in the `viewDidAppear` method of a custom `UIViewController`. However, when I press the "Done" button my custom view controller is dismissed automatically. I would like to intercept this action in order to use my own unwind Segue, but I'm not sure how to do this. I've found examples for `MPMoviePlayerViewController` but not `AVPlayerViewController`. The code I found for `MPMoviePlayerViewController` is below: ``` - (void)playVideo:(NSString *)aVideoUrl { // Initialize the movie player view controller with a video URL string MPMoviePlayerViewController *playerVC = [[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:aVideoUrl]] autorelease]; // Remove the movie player view controller from the "playback did finish" notification observers [[NSNotificationCenter defaultCenter] removeObserver:playerVC name:MPMoviePlayerPlaybackDidFinishNotification object:playerVC.moviePlayer]; // Register this class…

Accepted Answer

The fact that Apple provides no built-in way to handle the Done button is disappointing.

I didn't feel like inheriting from AVPlayerViewController, because it isn't supported by Apple and will probably open up a can of worms in one of the next iOS updates.

My workaround is to have a timer fire every 200 msec and check for the following condition:

```
if (playerVC.player.rate == 0 &&
   (playerVC.isBeingDismissed || playerVC.nextResponder == nil)) {
  // Handle user Done button click and invalidate timer
}
```

The player's `rate` property of 0 indicates that the video is no longer playing. And if the view controller is being dismissed or already dismissed, we can safely assume that the user clicked the Done button.
