title: How do I add UIBarButtonItems to a UIViewController.toolbarItems property using Interface Builder?
body: <p>I'm trying to use Interface Builder to add UIBarButtonItems to the toolbarItems property of the UIViewController.</p>
  
  <p>I have a .xib file and the File's Owner is typed as a subclass of UITableView controller ("ServerTableViewController"). I've dragged a bunch of UIBarButton items into the .xib file thinking that they will show up as part of the toolbarItems property of the ServerTableViewController that represents the File's Owner.</p>
  
  <p>Here's what I don't understand. Let's say I have an .xib file that has a ServerTableViewController in it which is <em>not</em> the File's Owner... I can drag UIBarButton items beneath it and they show up in its toolbar automatically!</p>
  
  <p>Why can I not do the same thing when ServerTableViewController is the File's Owner? That seems to be the only difference.</p>
