title: How can I have a UIView slide out from under a UINavigationBar?
body: <p>Currently I am displaying a UIView that slides down from the top of my window to a position:</p>
  
  <pre><code>-(void)showNotificationBar
  {
      [notificationBar setFrame: CGRectMake(0, 0, 320, 44)];
      [[[UIApplication sharedApplication] keyWindow] addSubview:notificationBar];
  
      [UIView animateWithDuration:0.5
                            delay:0.0
                          options: UIViewAnimationCurveEaseInOut
                       animations:^{
                           [notificationBar setFrame: CGRectMake(0, 59, 320, 32)];
                       } 
                       completion:^(BOOL finished){
                           NSLog(@"Done!");
                       }];
  }
  </code></pre>
  
  <p>I want this to slide out from under my UINavigationBar. Right now it is sliding from the top of the window, to the bottom of my navigation bar. I want it to slide from the bottom of the navigation bar to display itself. Now exactly sure how to do this?</p>
