title: Rotating UILabels depending on page in UIScrollView like in Google+ App
body: <p>I have an application with several (8) different Views in a UIScrollView. They are circling so that you get to the first when you try to get "behind" the last and vice versa.
  My problem is how to create a titlebar like in the Stream of the Google+ App. There the titles are circling with the pages and show the current visible page.
  How could I realize that? Would it be possible to create a general class to use such a view in many different apps?</p>
  
  <p>I've already tried to solve this problem with some different approaches, but they all didn't work (well). I can display labels above my scrollView and move them, but how far and with which text seems to be difficult for me.</p>
  
  <p>So now I'm looking forward to your answers ;D</p>
