iphone: не отображать баннер iad в навигации САМОЕ СЛОЖНОЕ?

Я уже прошел bees4honey, образцы iadsuites (все три) и всеми любимого репетитора raywenderlich. Ни один из них не помог мне отобразить баннер. У меня нет xib, о котором обычно упоминает большинство преподавателей. Это мой код делегата

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after app launch
    // Create the window object
    UIWindow *localWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    // Assign the localWindow to the AppDelegate window, then release the local window
    self.window = localWindow;
    [localWindow release];

    // Setup the first view controller
    HomeViewController *homeViewController = [[HomeViewController alloc] init];

    // Initialise the navigation controller with the first view controller as its root view controller
    navigationController = [[UINavigationController alloc] initWithRootViewController:homeViewController];

        [navigationController.navigationBar setBarStyle:UIBarStyleBlack];

    [navigationController.navigationBar setTintColor:[UIColor blackColor]];
            //[navigationController setNavigationBarHidden:YES];


        [HomeViewController release];



    // Add the navigation controller as a subview of our window
    [window addSubview:[navigationController view]];
    [window makeKeyAndVisible];

    return YES;
}

У меня есть HomeViewController (для навигации и методов) и HomeView (для подвидов). образец моего homeviewcontroller.m

#pragma mark -
#pragma mark Initialisation

- (id)init {
    self = [super init];
    if (self) {
        self.title = @"Home";

        UIView *homeView = [[HomeView alloc] initWithParentViewController:self];
        self.view = homeView;

        [homeView release];
    }
    return self;
}

#pragma mark -
#pragma mark Action Methods

- (void)button3Action {...........rest of code below as method for the button located in HomeView.m

пример кода с Homeview.m

// Private Methods
@interface HomeView()
- (void)loadButton3;

@end

@implementation HomeView

#pragma mark -
#pragma mark Initialization

- (id)initWithParentViewController:(HomeViewController *)parent {
    if ((self = [super init])) {
        // Update this to initialize the view with your own frame size
        // The design has specified that there is to be no status bar present,
        // please hide the status bar.
        [self setFrame:CGRectMake(0, 0, 320, 480)];

        // Assign the reference back to the parent view controller
        refParentViewController = parent;

        // Set the view background color
        [self setBackgroundColor:[UIColor lightGrayColor]];

        // Load subview methods
        [self loadButton3];

    }
    return self;
}

#pragma mark -
#pragma mark Load Subview Methods

- (void)loadButton3 {
    UIButton *button3 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [button3 setTitle:@"Is that counterfeit product?" forState:UIControlStateNormal];
    [button3 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [button3 setBackgroundColor:[UIColor clearColor]];
                button3.titleLabel.font = [UIFont fontWithName:@"MarkerFelt-Thin" size:25];
    [button3 addTarget:refParentViewController action:@selector(button3Action) forControlEvents:UIControlEventTouchUpInside];
    [button3 setFrame:CGRectMake(5, 375, 310, 31)];
    [self addSubview:button3];
}

было бы здорово, если бы кто-нибудь помог мне узнать, где именно мне нужно поместить «одобренный Apple код» в моем проекте для отображения баннера.

Спасибо =)
