推荐答案

我刚刚遇到这个错误。我在 UIAlert Action块中;当块退出时发生错误（BTW，父 UIAlertViewController 是在 dispatch_async块中创建的，所以我猜主要线程。

I just experienced this error. I was in a UIAlert Action block; when the block exited the error occurred (BTW the parent UIAlertViewController was created in a dispatch_async block so was I guess off main thread.

无论如何，我把行动代码包裹在

Anyway, I wrapped the action code itself in

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

       [self handleActionForElement:thisType];



    });

并且错误消失。您的里程可能会有所不同！

and error went away. Your mileage may vary!
