iAd在UITabBarController与故事板

Question

我想添加iAd到我的基于标签的应用程序使用故事板设置。我遵循Apple的iAdSuite示例代码中的TabbedBanner示例。我已经进口BannerViewController并进行如下设置：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    UITabBarController* tabBarController = (id)self.window.rootViewController; 
CGRect tabBarViewFrame = tabBarController.view.frame; 
tabBarViewFrame.origin.y -= application.statusBarFrame.size.height; 
tabBarViewFrame.size.height += application.statusBarFrame.size.height; 
tabBarController.view.frame = tabBarViewFrame; 

self.window.rootViewController = [[BannerViewController alloc] initWithContentViewController:tabBarController]; 
} 

我加入以下到我的SummaryViewController

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; 

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willBeginBannerViewActionNotification:) name:BannerViewActionWillBegin object:nil]; 
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFinishBannerViewActionNotification:) name:BannerViewActionDidFinish object:nil]; 
} 

的广告目前正在出现的标签栏下方？而且，我的观点的内容已经消失。

**请勿在最后一段代码中使用nil代替bundle。使用[NSBundle mainBundle]。
