title: I hide my AdBannerView but still get WARNING A banner view (0x9c75550) has an ad
body: <p>I have just added an ADBannerview in my App. I create the AdBannerView in my UIApplicationDelegate in order to have only one instance of it and I share it in the different viewController</p>
  
  <p>Everything works perfectly except I get the warning message: ADBannerView: WARNING A banner view (0x9c75550) has an ad but may be obscured. This message is only printed once per banner view.</p>
  
  <p>when I open a modal view (using presentModalViewController) on top of the view that is currently displaying the ADBannerview. Before opening the modal view I'm using the following code to hide the ADBannerview:</p>
  
  <pre><code>- (void)viewWillDisappear:(BOOL)animated
  {
      ADBannerView *bannerView = [ (ScoreBoardAppDelegate*)[[UIApplication sharedApplication] delegate] adBanner];
      [self hideBanner:bannerView];
      [super viewWillDisappear:animated];
  }
  
  - (void)hideBanner:(ADBannerView*) adBanner {
      NSLog(@"%s called", __FUNCTION__);
  
      // Grow the tableview to occupy space left by banner, it's the size of the parent view
      CGFloat fullViewHeight = self.tbView.frame.size.height;
      CGRect tableFrame = self.tv.frame;
      tableFrame.size.height = fullViewHeight;
  
      // Move the banner view offscreen
      CGRect bannerFrame = adBanner.frame;
  
      CGRect screenBounds = [[UIScreen mainScreen] bounds];
      bannerFrame.origin = CGPointMake(CGRectGetMinX(screenBounds), CGRectGetMaxY(screenBounds));
  
      self.tv.frame = tableFrame;
      adBanner.frame = bannerFrame;
  }
  </code></pre>
  
  <p>I don't understand what to do to not have this warning message. It seems the ADBannerView is successfully hidden (offscreen) before the Modal view is displayed.</p>
  
  <p>I probably missed something but I cannot see it.
  Thanks for your help,</p>
  
  <p>Sébastien.</p>
