title: iOS - deleting row from UITableView doesn't animate
body: <p>I have a very frustrating issue. I have an app with a UITableView. 
  When I am removing a cell from the table view, it is removed from the data model and then I call the following:</p>
  
  <pre><code>-(void)removeItem:(NSIndexPath *)indexPath {
      [self.tableView beginUpdates];
  
      [self.tableView deleteRowsAtIndexPaths:@[indexPath]
                        withRowAnimation:UITableViewRowAnimationRight];
      [self.tableView endUpdates];
  }
  </code></pre>
  
  <p>My problem is, I've tried it like I do above, and I've tried without using animateWithDuration. I've even tried with a CATransaction, but however I do it, the animation doesn't happen.</p>
  
  <p>I've got slow animations on in my Simulator and when I remove an item from the list, it removes correctly, but without animation.
  It just disappears and leaves a blank space for a moment before the table view data is reloaded.</p>
  
  <p>I've search all over SO and Google and I can't seem to find an answer.
  Any ideas?</p>
  
  <p>Does it perhaps have to do with the fact that I'm removing the object from the data model before calling the function above?</p>
  
  <p><strong>Edit: Removed the Animation Block as it is incorrect</strong>  </p>
