title: viewDidAppear for UITableViewCell
body: <p>I usually use <code>viewDidAppear</code> method to do some UI stuff on the view after it finished appearing and I used this method in various situations were it was very useful, however, I need to do some UI changes on a <code>UITableViewCell</code> after it finished appearing, is there any available method in the SDK that does a similar job like <code>viewDidAppear</code> but for <code>UITableViewCell</code> ?</p>
  
  <p>p.s. <code>willDisplayCell</code> did not work in my case, I need something like <code>didDisplayCell</code> if it really exists.</p>
