title: UISlider to control AVAudioPlayer
body: <p>I'm trying to implement a little function in my app. I am currently playing sounds as AVAudioPlayers and that works fine. What I would like to add is to control the sound's position (currentTime) with an UISlider: is there a simple way to do it ?</p>
  
  <p>I looked at an Apple project but it was quite messy....have you got samples or suggestions ?</p>
  
  <p>Thanks to everyone in advance</p>
