title: resignFirstResponder when tapping UITableView?
body: <p>I have a <code>UITableView</code> with two custom cells and each of them has a subview with a <code>UITextField</code> inside it. I have tried adding a <code>UIButton</code> on top of the <code>UITableView</code> and have it <code>resignFirstResponder</code> but that just means you won't be able to tap anywhere else - not even on the <code>UITextFields</code> to enter text.</p>
  
  <p>How do I make it so if I tap outside those two <code>UITextFields</code>, I can call resignFirstResponder, so the user can get back to the other cells?</p>
  
  <p>Thanks</p>
