title: How to tell the MPNowPlayingInfoCenter wether or not the music is playing or paused?
body: <p>I can't seem to make iOS show the correct play / pause button in the remote audio controls. I do receive the remote control events and set all values of the <code>nowPlayingInfo</code> dictionary.</p>
  
  <p>Everything works fine and I even see a cover photo on the lock screen. Except the pause/play button. It always looks like pause even if my <code>AVAudioPlayer</code> is playing. It sends a pause event regardless of playback state.</p>
  
  <p>How can I notify iOS that AVAudioPlayer is paused and that it should now show a play button in the remote control buttons bar?</p>
