  <p>The way I'm using Ad-Mob is this:</p>
  
  <pre><code>CGRect statusBarRect = [UIApplication sharedApplication].statusBarFrame;
  CGRect navigationBarRect = self.navigationController.navigationBar.frame;
  
  if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
  
      // Google AdMob
      // Initialize the banner at the bottom of the screen.
      CGPoint origin = CGPointMake(SCREEN_WIDTH / 2 - kGADAdSizeLeaderboard.size.width / 2
                                   ,
                                   SCREEN_HEIGHT
                                   - kGADAdSizeLeaderboard.size.height
                                   - navigationBarRect.size.height
                                   - 20);
  
  
      // Use predefined GADAdSize constants to define the GADBannerView.
      self.adBanner = [[GADBannerView alloc] initWithAdSize:kGADAdSizeLeaderboard origin:origin];
  
      // Note: Edit SampleConstants.h to provide a definition for kSampleAdUnitID before compiling.
      self.adBanner.adUnitID = kADMobBottomBannerPad;
      self.adBanner.delegate = self;
      self.adBanner.rootViewController = self;
  
      [self.view insertSubview:self.adBanner aboveSubview:self.scrollView];
      [self.adBanner loadRequest:[self request]];
  
  
  
  - (GADRequest *)request
  {
  GADRequest *request = [GADRequest request];
  
  // Make the request for a test ad. Put in an identifier for the simulator as well as any devices
  // you want to receive test ads.
  request.testDevices = @[
                          // TODO: Add your device/simulator test identifiers here. Your device identifier is printed to

  <p>I'm initializing Ad-Mob inside <strong>viewDidLoad</strong>. Delegate methods are set-up correctly. Am I missing something?</p>
  
  <p>Thanks!</p>
