title: UITableViewCell not resizing for UIView subview
body: <p>I added this library called <code>KSTokenView</code> which is a tokenizer like <code>NSTokenField</code>. This <code>UIView subclass</code> was added to the <code>UITableViewCell</code>. Connections were made with all the 4 sides of this <code>UIView</code> to the content view. Now as I type into the view and the size changes, there is a delegate method for change of frame. </p>
  
  <p>Using the frame change for that, I need to resize my tableviewcell and in turn the tableview also. </p>
  
  <p>In the view controller for the table view, I am giving an <code>estimated row height</code> of <code>UITableViewAutomaticDimension</code>. I am currently doing <code>tableView.beginUpdates</code> and <code>tableView.endUpdates</code> on change of frame. </p>
  
  <p>What is the correct way?</p>
