title: Start UICollectionView at a specific indexpath
body: <p>I currently have a collection view that does horizontal paging where each cell is fullscreen. What I want to do is for the collectionview to start at a specific index when it shows. </p>
  
  <p>Right now I'm using scrollToItemAtIndexPath:atScrollPosition:animated: with animated set to NO but that still loads the first index first before it can scroll to the specific item. It also seems I can only use this method in ViewDidAppear so it shows the first cell and then blinks to the cell that I want to show. I hide this by hiding the collection view until the scroll has finished but it doesn't seem ideal. </p>
  
  <p>Is there any better way to do this other than the way I described it? </p>
  
  <p>Thanks!</p>
