问题
I have an instance of a MPMoviePlayerController which is being used to display some live streaming video on an iPhone app. This is working fine, however I wish to remove all AirPlay functionality.
To be sure, I specifically disable AirPlay like so:
if([self.moviePlayerController respondsToSelector:@selector(setAllowsAirPlay:)]) {
self.moviePlayerController.allowsAirPlay = NO;
}
However, even with this code, I still see the AirPlay icon on the video controls. If I select this, and select my AppleTV, only the audio is sent over AirPlay - the video continues to play within the app. If I set allowsAirPlay to YES, both the video & audio are sent over AirPlay.
Does anyone know why this happens? Is this a feature of the OS, to allows allow the audio to be sent over AirPlay?
回答1:
It turns out that the AirPlay icon is still visible (and should remain visible) so that audio can be routed to any suitable device, eg. a Bluetooth headset. Attempting to hide the icon is considered bad practice.

I known its an old question but still maybe this will help someone else.
Apple has the following api to hide the route button (AirPlay)
@property (nonatomic) BOOL showsRouteButton NS_AVAILABLE_IOS(4_2); // Default is YES.
Hope this helps anyone.

@Philip K, your hint almost solved this for me, debugging some four year old code. showsRouteButton isn't a property on the MPMoviePlayerController, and I tried setting:
myMPMoviePlayer.allowsAirPlay = NO;
But this did nothing...
And we are using custom controls for our video player, and found that the route button is a part of the MPVolumeView, and your trick applies there:
MPVolumeView * vView = [[MPVolumeView alloc] initWithFrame: bounds];
vView.showsRouteButton = NO;
Bingo! Thanks.
