AVPlayer layer inside a view does not resize when UIView frame changes

Question

I have a UIView which contains an AVPlayer to show a video. When changing orientation, I need to change the size and location of the video.

Answer 1

In the end I solved this by re-adding the AVPlayerLayer to the UIView. I'm not sure why changing the frame removed the layer, but it did. Here's the final solution:

//amend the frame of the view
[videoHolderView setFrame:CGRectMake(0, 0, 768, 502)];

//reset the layer's frame, and re-add it to the view
AVPlayerLayer* playerLayer = [AVPlayerLayer playerLayerWithPlayer:self.avPlayer];
playerLayer.frame = videoHolderView.bounds;
[videoHolderView.layer addSublayer:playerLayer];
