title: How to automatically call a method after popping a view controller off the stack on the iPhone
body: <p>I need to update the parent view on an iPhone after popping a child view off the navigation stack.  How can I setup the parent view to be notified or receive an automatic method call when the child is popped off the stack and the parent becomes visible again?</p>
  
  <p>The user enters data on the child page that I want to display on the parent page after the user is done and pops the view.</p>
  
  <p>Thanks for you help!</p>
