title: Animate UITableView change
body: <p>I have a two row tableview (username and password) and when the user hits enter it tries to login and switches the two cells to a single loading cell. While I am going from 2 to 1 cell, the new cell is twice as large (minus 1 px for the separator). I would like to fade between the two states.</p>
  
  <p>How would I do this?</p>
