尝试实施iAd后，我的应用程序无法打开！

我一直在尝试将iAds实现到我的应用程序中，但这是发生的事情：

1.点击应用2.Loading屏幕显示几秒钟3.App崩溃

这是什么返回：

附：我是iPhone新手

谢谢

这是我的代码：

@implementation Vampire_Quiz_FinalViewController

- (IBAction)V;

{

    Vork *V = [[Vork alloc] initWithNibName:nil bundle:nil];

    [self presentModalViewController:V animated:NO];

}
- (IBAction)A;

{

    About *A = [[About alloc] initWithNibName:nil bundle:nil];

    [self presentModalViewController:A animated:NO];

}
- (IBAction)I;

{

    Instructions *I = [[Instructions alloc] initWithNibName:nil bundle:nil];

    [self presentModalViewController:I animated:NO];

}

- (void)dealloc {
    [super dealloc];
}

- (void)viewDidLoad {

    adView = [[ADBannerView alloc] initWithFrame:CGRectZero];

    adView.frame = CGRectOffset(adView.frame, 0, -50);

    adView.requiredContentSizeIdentifiers = [NSSet setWithObject:ADBannerContentSizeIdentifier320x50];

    adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifier320x50;

    [self.view addSubview:adView];

    adView.delegate=self;

    self.bannerIsVisible=NO;

    [super viewDidLoad];

}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner

{

    if (!self.bannerIsVisible)

    {

        [UIView beginAnimations:@"animateAdBannerOn" context:NULL];

        // banner is invisible now and moved out of the screen on 50 px

        banner.frame = CGRectOffset(banner.frame, 0, 50);

        [UIView commitAnimations];

        self.bannerIsVisible = YES;

    }

}



- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error

{

    if (self.bannerIsVisible)

    {

        [UIView beginAnimations:@"animateAdBannerOff" context:NULL];

        // banner is visible and we move it out of the screen, due to connection issue

        banner.frame = CGRectOffset(banner.frame, 0, -50);

        [UIView commitAnimations];

        self.bannerIsVisible = NO;

    }

}



@end

我该怎么办呢???
