title: Play notification sound using URL
body: <p>I want my application to play notification sound through <code>URL</code>. My custom sound file lies at a particular working <code>URL</code>. So, I want my app to use that link to notify user about notification.</p>
  
  <p>I've tried <code>AVPlayer</code>,since it plays sound files through URL's <a href="https://stackoverflow.com/questions/13131177/streaming-mp3-audio-with-avplayer">Check this</a></p>
  
  <p>The <code>AVPlayer</code> code is working when I call it using <code>[self playselectedsong]</code> (plz check code provided in above link) in <code>didFinishLaunchingWithOptions</code> of <code>AppDelegate</code> and <code>viewDidLoad</code> function of other views.</p>
  
  <p>Whenever the notification arrives(<code>didReceiveRemoteNotification</code>) with an audio file <code>URL</code>,which then I add into the <code>AVPlayer</code>,the sound isn't playing.Only the text notification is shown.</p>
