Detect volume button press, also hide volume HUD
import MediaPlayer //Only for hidding Volume view
func listenVolumeButton(){
let audioSession = AVAudioSession.sharedInstance()
audioSession.setActive(true, error: nil)
audioSession.addObserver(self, forKeyPath: "outputVolume", options: NSKeyValueObservingOptions.New, context: nil)
//If you want to hide Volume HUD view
var volumeView: MPVolumeView = MPVolumeView(frame: CGRectZero)
view.addSubview(volumeView)
}
override func observeValueForKeyPath(keyPath: String, ofObject object: AnyObject,
change: [NSObject : AnyObject], context: UnsafeMutablePointer<Void>) {
if keyPath == "outputVolume"{
print("got in here")
}
}
