title: How do I achieve UINavigationBar animation while scrolling up in iOS Music App?
body: <p>When you go to the native iOS Music application you will notice a very cool effect when viewing an Album. </p>
  
  <p>It seems like the view is a UITableView that has a transparent UINavigationController and when you scroll up, the first row of the view fades away and into a navigation bar with the album title. </p>
  
  <p>What is actually going on here and is there a known framework that does this? </p>
