ios - No "Done" button on AVPlayerViewController

I am using AVPLayerViewController to stream content. Playback works fine but I don't see "Done" button to dismiss the view.

Here is I how I setup and show the view controller

NSURL* url = [content localSessionUrl];
AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.player = [AVPlayer playerWithURL:url];
[self.navigationController pushViewController:playerViewController animated:YES];
[self.navigationController setNavigationBarHidden:YES];

Is it because I am pushing it on a navigationcontroller? enter image description here

Instead of pushing or add child view, try to present the view. The Done button will automatically shown. Below is the code snippet.

-(void)playVideoWithUrl:(NSURL *)url{
    AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc]init];
    playerViewController.player = [[AVPlayer alloc]initWithURL:url];
    [self presentViewController:playerViewController animated:YES completion:nil];
    playerViewController.view.frame = self.view.frame;
    [playerViewController.player play];
}
