Start UICollectionView at bottom

Question

In iOS 7, given a UICollectionView, how do you start it at the bottom? Think about the iOS Messages app, where when the view becomes visible it always starts at the bottom (most recent message).

Answer 1

This works for me and i think it is a modern way.

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    self.collectionView!.scrollToItemAtIndexPath(indexForTheLast, atScrollPosition: UICollectionViewScrollPosition.Bottom, animated: false)
}
