title: Is there any notification for detecting AirPlay in Objective-C?
body: <p>I am using MPVolumeView for showing Airplay icon and it works fine. </p>
  
  <p>But I need to show an animation when Airplay network comes, and hide that animation when airplay network hides.</p>
  
  <p>Is there a notification that will let me know when Airplay starts and ends?</p>
