Admob GADBannerView.m bool _WebTryThreadLock(bool) iOS iPhone 崩溃

Question

我使用 admob sdk 在 iPhone 3.1.3（第一代 iPhone）上运行该应用程序。我一直以为不是，最近我开始遇到这个错误，这是我以前从未见过的。

<Warning>: bool _WebTryThreadLock(bool), 0x3c3840: Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread. Crashing now...

然后当我在日志文件中追踪错误时，我看到

Thread 6 Crashed:

13  My iPhone App                       0x000135c4 0x1000 + 75204

并进一步追踪它并得到，

-[GADBannerView dealloc] (in My iPhone App) (GADBannerView.m:111)

-[myViewController dealloc] (in My iPhone App) (myViewController.m:378)

-[mySubViewController dealloc] (in My iPhone App) (mySubViewController.m:64)

我不知道发生了什么。我可以采取什么措施来防止崩溃，还是 admob 必须解决这个问题？

任何帮助表示赞赏

尝试使用调试器来了解错误发生的位置。也是从您调用removeFromSuperView 方法的地方。这可能会导致问题
