title: How to dismiss keyboard when using DecimalPad
body: <p>I have a <code>UITableView</code> with a custom cell that has a <code>TextField</code>. I have the <strong>DecimalPad</strong> comes up, and as we all know, there is no done key. I previously had resolved this type of issue when I had a "Decimal only" textfield on a normal UIView by handling the <code>TouchesEnded</code> event and then checking to see if the <code>TextField</code> was the first responder and if so, it would then resign, but if that technique could work now then I'm not able to figure out who's <code>TouchesEnded</code> I should be using (The <code>UIView</code> that everything is presented on, the <code>UITableView</code>, the Cell, the CellControler, the TextField.. I think I've tried everything). </p>
  
  <p>I'm hoping there's another, cleaner way of dealing with this.</p>
  
  <p>Anyone?</p>
