title: Present Modal View in iOS 6
body: <p>I want to display a modal view but I have two problems:</p>
  
  <ol>
  <li><p>There is no presentModalViewController in iOS 6 and I have to use presentViewController which is just display my second ViewController like a modal segue not a modal window without full screen option,</p></li>
  <li><p>My second problem is how can I show the modal window from UICollectionViewController. I tried to use presentViewController but it just works with ViewController not CollectionViewController.</p></li>
  </ol>
  
  <p>The best example of what I want to do is this (Instagram). How they made this modal window? Is it because it's still working with older iOS versions and it's not iOS 6 yet? Or there is another way to display modal window like this from UICollectionViewController?</p>
  
  <p>Thanks</p>
