Ios SIGSEGV-[GADDelegateManager didReceiveAd]

我在我的iOS应用程序上与谷歌广告暴徒发生了奇怪的崩溃。事故日志如下：

或：

我使用Ad Mob的方式是：

CGRect statusBarRect = [UIApplication sharedApplication].statusBarFrame;
CGRect navigationBarRect = self.navigationController.navigationBar.frame;

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {

    // Google AdMob
    // Initialize the banner at the bottom of the screen.
    CGPoint origin = CGPointMake(SCREEN_WIDTH / 2 - kGADAdSizeLeaderboard.size.width / 2
                                 ,
                                 SCREEN_HEIGHT
                                 - kGADAdSizeLeaderboard.size.height
                                 - navigationBarRect.size.height
                                 - 20);


    // Use predefined GADAdSize constants to define the GADBannerView.
    self.adBanner = [[GADBannerView alloc] initWithAdSize:kGADAdSizeLeaderboard origin:origin];

    // Note: Edit SampleConstants.h to provide a definition for kSampleAdUnitID before compiling.
    self.adBanner.adUnitID = kADMobBottomBannerPad;
    self.adBanner.delegate = self;
    self.adBanner.rootViewController = self;

    [self.view insertSubview:self.adBanner aboveSubview:self.scrollView];
    [self.adBanner loadRequest:[self request]];



- (GADRequest *)request
{
GADRequest *request = [GADRequest request];

// Make the request for a test ad. Put in an identifier for the simulator as well as any devices
// you want to receive test ads.
request.testDevices = @[
                        // TODO: Add your device/simulator test identifiers here. Your device identifier is printed to
                        // the console when the app is launched.
                        GAD_SIMULATOR_ID
                        ];
return request;
}  

我正在初始化viewDidLoad中的广告移动。委托方法设置正确。我错过什么了吗

谢谢

这是一个生命周期问题吗？例如，假设您有两个视图，用户可以在它们之间进行制表。如果第一个视图的代理在第二个视图出现时被释放，并且广告系统试图调用不再可用的第一个视图代理，则会发生崩溃

您可以使用NSZombie（模式设置中的运行选项）来检测发布后的使用错误。

嗨，Faisal，感谢您的快速回复，我尝试了您的建议，但我无法重现错误。我试着在好的网络，坏的，快速的控制器之间切换，什么都没有。。。你还有其他建议吗？有时当我遇到一个棘手的UI生成崩溃时，我会使用JavaScript可访问性界面来自动使用UI，然后运行一个程序来不断尝试排列和计时。还有猴子测试的概念——脚本随机按下UI和其他相关UI事件。谢谢你的帮助！通过添加_addBanner.delegate=nil解决；在Dealoc内部。我也在谷歌文档里找到了这个，我第一次错过了！
