ios – ADBannerView控制台中显示未处理的错误

我按照苹果开发指南文档以编程方式在我的iOS应用程序上添加iAd.虽然我在stackoverflow上搜索了之前的解决方案,但不幸的是它们似乎都没有帮助我.有以下错误：

代码如下

#import <iAd/iAd.h>
@interface SinglePlayerViewController : UIViewController <ADBAnnerViewDelegate>

    {
    ADBAnnerView *adView;
    }

SinglePlaerViewController.m代码：

- (void)viewDidLoad
    {
        [super viewDidLoad];

        adView = [[ADBAnnerView alloc] initWithFrame:CGRectZero];
        adView.currentContentSizEIDentifier = ADBAnnerContentSizEIDentifierPorTrait;
        CGRect adFrame = adView.frame;
        adFrame.origin.y = self.view.frame.size.height-adView.frame.size.height;
        adView.frame = adFrame;
        adView.delegate =self;
        [self.view addSubview:adView];
    }
-(void) bAnnerView:(ADBAnnerView *)bAnner didFailToReceiveAdWithError:(NSError *)error
{
    NSLog(@"iAdBAnner Failed");
}
-(void) bAnnerViewDidLoadAd:(ADBAnnerView *)bAnner
{

    NSLog(@"iAdBAnner loaded"); 
}

@interface SinglePlayerViewController : UIViewController<ADBAnnerViewDelegate>

@property (nonatomic,retain) ADBAnnerView *adView;

@end

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.adView = [[ADBAnnerView alloc] initWithFrame:CGRectZero];
    self.adView.currentContentSizEIDentifier = ADBAnnerContentSizEIDentifierPorTrait;
    CGRect adFrame = self.adView.frame;
    adFrame.origin.y = self.view.frame.size.height-self.adView.frame.size.height;
    self.adView.frame = adFrame;
    self.adView.delegate =self;
    [self.view addSubview:self.adView];
}
