How to check if the device is connected via airplay?

Question

I had the problem to check if I am connected to an airplay device and if it is connected via mirroring or streaming. But the check needs to be done before the video started.

Answer 1

Swift version:

var isAudioSessionUsingAirplayOutputRoute: Bool {

    let audioSession = AVAudioSession.sharedInstance()
    let currentRoute = audioSession.currentRoute

    for outputPort in currentRoute.outputs {
        if outputPort.portType == AVAudioSessionPortAirPlay {
            return true
        }
    }

    return false
}

And checking the screen count:

if UIScreen.screens.count < 2 {
    //streaming
} else {
    //mirroring
}
