在本机调试可以看到广告条，发布到商店上之后，就看不到了……

代码如下：

#pragma mark 广告的实现

- (instancetype)init
{
    self = [super init];
    if (self) {
       ...

        Class classAdBannerView = NSClassFromString(@"ADBannerView");

                _adView = [[ADBannerView alloc] initWithAdType:ADAdTypeBanner];

            } else {
                _adView = [[ADBannerView alloc] init];
            }
            //_adView.requiredContentSizeIdentifiers = [NSSet setWithObject:ADBannerContentSizeIdentifierPortrait];
            //_adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
            [_adView setAutoresizingMask:UIViewAutoresizingFlexibleWidth];

            _adView.delegate = self;
            [self layoutAnimated:YES];
        }
    }
    return self;
}


- (void)layoutAnimated:(BOOL)animated

    // To support iOS 5.0 however, we continue to set the currentContentSizeIdentifier appropriately.

}
