问题描述

我在gdb中遇到了这个奇怪的错误，我无法追踪确切的代码行来追踪错误。有人知道这种类型的错误吗？这里是我在gdb中获得的信息

I am getting this strange error in gdb and i'm unable to trace the exact line of code to trace the bug. Does someone knows about this type of bug? Here is what i get in gdb

推荐答案

解决问题的办法。问题是由于视图控制器。视图控制器被释放，然后在调用方法之后。但奇怪的gdb没有显示任何关于viewController relese ....都没有打开NSZombie帮助。

I've got the solution to the problem. The problem was due to a view Controller. The view controller was released and then after the method was called. But strange gdb didn't show anything about viewController relese....Neither turning on NSZombie helped.
