title: How to create cover flow with different view controllers?
body: <p>I want to show view controllers's view as images in tiles. But how to get the images of all view controllers before loading those view controllers. Suggest me some solution. I was looking through the link <a href="http://www.chaosinmotion.com/flowcover.m" rel="nofollow">Flowcover</a> </p>
  
  <p><strong>EDIT</strong></p>
  
  <p>But My views have graphs, which is drawn from a dynamic content(fetched from web service). How could I take a screenshot without loading the view?  If not, can u suggest me some other solution to display in 'tiles'. </p>
