title: iOS: UITableView parallax header effect like Spotify
body: <p>I recently received the latest Spotify iPhone/iPod update and thought their new UI was fantastic. I want to try to replicate their playlist parallax effect, Im struggling to grasp what it is that they have done though. I've uploaded a video to <a href="https://www.youtube.com/watch?v=fE2Qye9bgjw&amp;feature=youtu.be" rel="nofollow">YouTube</a> displaying the effect I want to achieve. My best guess is that they're using some kind of custom table header, since it sticks to the top and some scrollview delegate to show/hide different labels. Anybody out there who can figure this one out?</p>
  
  <p>I've found things like <a href="http://rowboatrevolution.com/2012/02/uitableview-parallax-background-a-la-path/" rel="nofollow">this</a> where they have a UIImageView behind the tableview but that doesn't really replicate the header-like behavior where a bit of the image sticks to the top. Also, having the controls for 'back' and 'options' would be a hazzle.</p>
