iAd 错误回调发生了奇怪的崩溃。这是我的崩溃日志：

iAd 的委托回调：

- (void) bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
    DLog(@"IAD Failed to load with error %@", error);

    self.adBannerContainer.hidden = YES;

    if (InternetAvailableWithAlert(NO))
    {
        if (self.gadAvailable)
        {
            self.gadBannerContainer.hidden = NO;
        }
        else
        {
            [self requestGAD];
        }
    }
}

- (void) requestGAD
{
    GADRequest* request = [[GADRequest alloc] init];

#if TARGET_IPHONE_SIMULATOR

    request.testDevices = @[GAD_SIMULATOR_ID];

#endif

    self.gadBanner.rootViewController = (self.gadBanner.rootViewController ?: self.viewController);
    [self.gadBanner loadRequest:request];
}

iAd 视图委托是一个从未发布的单例。即使它已发布，iAd 类委托属性也是一个弱属性，因此它应该自动为零。

@property (nonatomic, weak) id<ADBannerViewDelegate> delegate;

想法？

这是由于将 Admob SDK 根视图控制器设置回自身，当视图控制器被释放时，这会崩溃。Admob SDK 使用分配引用而不是弱引用，这就是它崩溃的原因。
