Is there any public api to detect AirPlay available or not

Question

I have implement the MPVolumeView to show Airplay option but I don't know how to hide MPVolumeView if Airplay options/sources are no longer available.

Is there any public API which can detecting AirPlay option/source are available or not. So that application can hide/show the airplay option.

NOTE: I am using custom player not the default MPMoviePlayerController

Thanks!

I see two approaches that would work:

1. Set MPVolumeView's showsVolumeSlider to NO and the AirPlay route button picker "...is visible only when there is an AirPlay output device available."

2. Add observer for MPVolumeViewWirelessRoutesAvailableDidChangeNotification and hide or remove your subview.

   - (void)viewWillAppear:(BOOL)animated {
     [[NSNotificationCenter defaultCenter] addObserver:self
                                              selector:@selector(handleWirelessRoutesDidChange:)
                                                  name:MPVolumeViewWirelessRoutesAvailableDidChangeNotification object:nil];
   }
   
   - (void)viewWillDisappear:(BOOL)animated {
       [[NSNotificationCenter defaultCenter] removeObserver:self];
   }
   
   - (void)handleWirelessRoutesDidChange:(NSNotification *)notification {
       NSLog(@"Wireless routes did change: %@", notification);
       // Hide or remove your MPVolumeView
   }
