iAd横幅不能在iOS 9上运行

在模拟器和设备上运行时,我在控制台中收到didFailToReceiveAdWithError消息.

在iOS 8上运行时,iAd横幅显示成功.当在iOS 9上运行时,iAd横幅无法收到广告.

.H

#import <iAd/iAd.h>
@interface ViewController : UIViewController <ADBannerViewDelegate>

@property (retain,nonatomic) IBOutlet ADBannerView *adBanner;

.M

-(void)viewDidLoad {
    self.adBanner = [[ADBannerView alloc]initWithFrame:CGRectMake(0,[UIScreen mainScreen].bounds.size.height-100,[UIScreen mainScreen].bounds.size.width,50)];
    self.adBanner.delegate=self;
    [self.adBanner setBackgroundColor:[UIColor clearColor]];
    [self.view addSubview:self.adBanner];
}   

-(void)bannerViewWillLoadAd:(ADBannerView *)banner {
    NSLog(@"bannerViewWillLoadAd");
}

-(void)bannerViewDidLoadAd:(ADBannerView *)banner {
    // Show the ad banner.
    NSLog(@"bannerViewDidLoadAd");

    [UIView animateWithDuration:0.5 animations:^{
        self.adBanner.alpha = 1.0;
    }];
}

-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
    NSLog(@"didFailToReceiveAdWithError");

    // Hide the ad banner.
    [UIView animateWithDuration:0.5 animations:^{
        self.adBanner.alpha = 0.0;
    }];
}    

-(void)bannerViewActionDidFinish:(ADBannerView *)banner {
    NSLog(@"Ad did finish");
}

当在iOS 9上运行时,控制台每次都会打印出didFailToReceiveAdWithError.

解决方法

我无法重新创建您的问题. iAd网络可能在测试时可能已针对您所在的国家/地区,您可能在iAd不支持的国家/地区,或者您可能将iAd测试填充率设置为开发设备/模拟器的0％.转到设置>开发人员>填充率>并在开发设备/模拟器上检查填充率是否设置为100％.

建议您使用didFailToReceiveAdWithError打印您收到的错误,以便您可以找到ADBannerView为什么失败.

-(void)viewDidLoad {
    // The ADBannerView will size itself based on the device it is being displayed on
    // Only setting the position is sufficient
    self.adBanner = [[ADBannerView alloc]initWithFrame:CGRectMake(0,0)];
    self.adBanner.delegate=self;
    // Removed setBackgroundColor
    // Set alpha to 0.0 initially
    self.adBanner.alpha = 0.0;
    [self.view addSubview:self.adBanner];
}

-(void)bannerViewWillLoadAd:(ADBannerView *)banner {
    NSLog(@"bannerViewWillLoadAd");
}

-(void)bannerViewDidLoadAd:(ADBannerView *)banner {
    NSLog(@"bannerViewDidLoadAd");
    [UIView animateWithDuration:0.5 animations:^{
        self.adBanner.alpha = 1.0;
    }];
}

-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
    // Changed NSLog to print the error that is received
    NSLog(@"didFailToReceiveAdWithError: %@",error);
    [UIView animateWithDuration:0.5 animations:^{
        self.adBanner.alpha = 0.0;
    }];
}

-(void)bannerViewActionDidFinish:(ADBannerView *)banner{
    NSLog(@"bannerViewActionDidFinish");
}
