Question

由于iAd，我得到了一个非常奇怪的崩溃。这是调试器输出：

您确定已发布bannerView的代表吗？我创建了一个名为“releaseBannerView”的方法。我是这样做的，所以我可以“弱”链接我的iAd.framework，并且只有在iAd类存在的情况下才调用该方法。对于向后的能力非常有效。

-(void)releaseBannerView {
//Test for the ADBannerView Class, 4.0+ only (iAd.framework "weak" link Referenced)

Class iAdClassPresent = NSClassFromString(@"ADBannerView");

//If iOS has the ADBannerView class, then iAds = Okay:
if (iAdClassPresent != nil) {

    //If instance of BannerView is Available:
    if (self.bannerView) {

        //Release the Delegate:
        bannerView.delegate = nil;

        //Release the bannerView:
        self.bannerView = nil;
        }
    }
}

然后在需要的时候，在我的Dealloc方法中，我可以通过调用这个方法来取消bannerView：

- (void)dealloc {
 [super dealloc];
 [self releaseBannerView];
 ..and.others...
}

奇怪的iAd错误导致崩溃
