changing AVPlayer orientation

I need change my AVPlayer orientation when device orientation is changed. I set _playerLayer.frame = perentView.bounds but it doesn't helped _playerLayer = [AVPlayerLayer playerLayerWithPlayer:_videoPlayer]; _playerLayer.frame = perentView.bounds; _playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill; [perentView.layer insertSublayer:_playerLayer atIndex:0];
