iAd"没有委托或委托没有实现didFailToReceiveAdWithError:"

Question

我运行我的应用程序禁用wifi,我总是在调试器中获得空白和此消息:

ADBannerView:未处理的错误(没有委托或委托没有实现didFailToReceiveAdWithError :):错误域= ADErrorDomain代码= 5"操作无法完成.横幅视图可见但没有内容"UserInfo = 0x9632d30 {ADInternalErrorCode = 5, NSLocalizedFailureReason =横幅视图可见,但没有内容}

请帮我修改我的代码:.h

#import <iAd/iAd.h>
@interface ViewController : UIViewController  <GKAchievementViewControllerDelegate, GameCenterManagerDelegate , ADBannerViewDelegate> {


//iAD
ADBannerView *banner;  
 }

//iAD
@property (nonatomic, assign) BOOL bannerIsVisible;
@property (nonatomic, retain) IBOutlet ADBannerView *banner;  

.M

@synthesize  banner , bannerIsVisible;
-(void)bannerViewDidLoadAd:(ADBannerView *)abanner {
if (!self.bannerIsVisible) {
    [UIView beginAnimations:@"animatedAdBannerOn" context:NULL];
    banner.frame = CGRectOffset(banner.frame, 0.0, 50.0);
    [UIView commitAnimations];
    self.bannerIsVisible = YES;
}}

-(void)bannerView:(ADBannerView *)aBanner didFailToReceiveAdWithError:(NSError *)error {
if (!self.bannerIsVisible) {
    [UIView beginAnimations:@"animatedAdBannerOff" context:NULL];
    banner.frame = CGRectOffset(banner.frame, 0.0, -50.0);
    [UIView commitAnimations];
    self.bannerIsVisible = NO;
}

}

根据错误的委托部分.在viewDidLoad(或初始化的任何位置)方法集banner.delegate = self;
