title: Can you stop a modal view from dismissing?
body: <p>I have a view that uses a modal view with a page curl to allow for a username to be entered.  This username is then verified with a web-based service to see if it is valid.  </p>
  
  <p>Everything works great until you enter an invalid username and click outside the modal view.  This still checks the username, which is reported invalid and a <code>UIAlertView</code> opens.  However, it goes back to the parent view.  </p>
  
  <p>Is there any way to get the modal to not dismiss in this case?  </p>
  
  <p>I have tried to reload the view but either it isn't working or the <code>UIAlertView</code> is blocking it.  The last idea I have is to couple displaying the modal view with the "OK" on the alert for an invalid username.  Anyone have any ideas?</p>
