I've got an instance of AVPlayer which plays some media, but I don't want user to be able to stream it via AirPlay. So I set allowsExternalPlayback property of AVPlayer to NO. However it doesn't seem to affect AirPlay button in control center, so it stays visible. Is there any way to hide the button?
