它说线程 11 崩溃了，但这看起来像主线程崩溃，正如我从最后一行看到的那样。线程 11 堆栈跟踪看起来像这样

   Thread 11 Crashed:
0   libsystem_kernel.dylib          0x3c4a4d98 __workq_kernreturn + 8
1   libsystem_c.dylib               0x3c3f2cf6 _pthread_workq_return + 14

3   libsystem_c.dylib               0x3c3f28a0 start_wqthread + 4

此外，崩溃报告指出应用程序在进行枚举时崩溃了，但我不确定它与 UIView 和 UITableView 对象有何关系，正如我从堆栈跟踪中看到的那样。一些更多的信息，我有一个 TableView ，它显示了一个列表，如果数据，这是从服务器获取的。

有人能帮我解决这个问题吗？

谢谢

@nkd，为什么不使用崩溃报告管理器，Crashlytics它执行两步符号化过程，一次在应用程序端，一次在服务器端，通过所有线程信息、测试环境等为您提供崩溃的确切位置。我一直在广泛使用它，对解决错误有很大帮助。
