title: UIMenuController not showing up
body: <p>I'm trying to create a custom UIMenuController and display it in my view. Here's my code:</p>
  
  <pre><code>UIMenuController *menuController = [UIMenuController sharedMenuController];
      UIMenuItem *listMenuItem = [[UIMenuItem alloc] initWithTitle:@"List" action:@selector(addList:)];
  
      [menuController setMenuItems:[NSArray arrayWithObject:listMenuItem]];
      [menuController setTargetRect:CGRectMake(50.0, 50.0, 0, 0) inView:self.view];
      [menuController setMenuVisible:YES animated:YES];
  
      [listMenuItem release];
  </code></pre>
  
  <p>There are no errors or exceptions, but the menu controller just doesn't show up.</p>
