title: Transitioning between subviews in a navigationController?
body: <p>In my app I have a drill-down type interface as follows:<br>
  My root view, which has a list of items and an "Add" button.<br>
  Selecting an item pushes the "Detail" view on the navigationController.<br>
  Selecting the "Add" button pushes an "Add" view.</p>
  
  <p>How would I transition between the Add view to the Detail view?</p>
  
  <p>I'm thinking of doing an unanimated "pop" on the Add view and push the Detail controller on, but how do I make the second part animated, so the detail view would either slide in vertically or fade in from the Add view?</p>
  
  <p>Thanks,<br>
