title: No "Done" button at AVPlayerViewController Objective C
body: <p>I can't seem to create the "Done" button at my video. I have attached my code below:</p>
  
  <pre><code>- (IBAction)playVideoButton:(id)sender {
  
      NSString *path = [[NSBundle mainBundle] pathForResource:@"Video1" ofType:@"mp4"];
  
      NSURL *url = [NSURL fileURLWithPath:path];
  
      AVPlayer *player = [AVPlayer playerWithURL:url];
      AVPlayerViewController *controller = [[AVPlayerViewController alloc]init];
      controller.player = player;
      //to view on full UIScreen
  
      self.mc = controller;
      controller.view.frame = self.view.bounds;
      [self.view addSubview:controller.view];
      [player play];    
  }
  </code></pre>
