title: Does the UITableView "beginUpdates" and UICollectionView "performBatchUpdates" have the same behavior?
body: <p>I was browsing the documentations, when I started wondering if "beginUpdates" in a UITableView and "performBatchUpdates" in a UICollectionView have the same behavior. If so, is there a reason, that they're called differently, even though they're virtually the same thing?</p>
  
  <p>Thanks!</p>
