title: AVPlayer force landscape mode for fullscreen
body: <p>I am playing a video using an AVPlayer which is about 320x200 frame in my app. The avplayer also has a custom 'fullscreen' button added as overlay, like the youtube app player. How can I implement it such that when the app is in portrait mode and the user clicks fullscreen button, the video will rotate to fullscreen but in landscape mode? I tried using transform and it works partially, because when its in fullscreen mode, if user switches device to portrait orientation; the avplayer frame changes abruptly. I want it to work like the youtube app i.e. when in fullscreen mode, it should stay so even if user rotates device. Only should return to original size when turn off fullscreen. I don't want to use avplayerviewcontroller due to design of the app. Thanks in advance for help.</p>
