问题描述

我在 gdb 中遇到了这个奇怪的错误，我无法跟踪确切的代码行来跟踪错误.有人知道这种类型的错误吗?这是我在 gdb 中得到的内容

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

我已经找到了问题的解决方案.问题是由于视图控制器.视图控制器被释放，然后在方法被调用之后.但是奇怪的 gdb 并没有显示任何关于 viewController relese 的信息......打开 NSZombie 也没有帮助.

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.
