How to get the AirPlay device name without using iOS7 deprecated methods

Question

I'm using the method described here Get name of AirPlay device using AVPlayer to retrieve the name of the AirPlay device connected.

But AudioSessionGetProperty and kAudioSession_AudioRouteKey_Outputs are deprecated in iOS7. I'm looking for an alternative method to do this :)

Starting from iOS6 AudioSession exposes currentRoute to you, which allows retrieving it's port information as well as listening to audioRouteChangeNotification. (so you no longer need to use C-based API from AudioToolbox framework):

NSString* airplayName = [self activeAirplayOutputRouteName];
if (airplayName) {
    //airplay is active

}

(what you want to get is the portDescription of currentAudioRoute):

- (NSString*)activeAirplayOutputRouteName
{
    AVAudioSession* audioSession = [AVAudioSession sharedInstance];
    AVAudioSessionRouteDescription* currentRoute = audioSession.currentRoute;
    for (AVAudioSessionPortDescription* outputPort in currentRoute.outputs){
        if ([outputPort.portType isEqualToString:AVAudioSessionPortAirPlay])
            return outputPort.portName;
    }

    return nil;
}
