如何调试和解决AFNetworking中的崩溃问题

Question

我的iOS应用程序使用AFNetworking(2.6.1),我的排名最高的崩溃是:

Crashed: com.apple.NSURLSession-work
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0004000128ab38a0

这就是Crashlytics中大多数堆栈跟踪的样子:

Thread : Crashed: com.apple.NSURLSession-work
0  libobjc.A.dylib                0x180e29bc8 objc_msgSend + 8
1  CFNetwork                      0x181df6518 SessionConnectionLoadable::_loaderClientEvent_DidReceiveConnectionCacheKey(HTTPConnectionCacheKey*) + 56
2  CFNetwork                      0x181e75178 ___ZN19URLConnectionLoader36protocolDidReceiveConnectionCacheKeyEP22HTTPConnectionCacheKey_block_invoke + 40

9  libsystem_pthread.dylib        0x181411470 _pthread_wqthread + 1092
10 libsystem_pthread.dylib        0x181411020 start_wqthread + 4

我不使用kvo,我的应用程序使用位置并始终保持在后台.

关于如何调试/重新创建的任何想法(我无法在模拟器或设备上重建问题)？即使抓住异常,也不知道它在哪里或如何正确处理它就足够了......
