打破_NSLockError（）来调试...如何？ [英] Break on _NSLockError() to debug ... How to?

问题描述

在调试期间，控制台总是会吐出一个错误信息：将_NSLockError（）中断以调试

During debugging the console always spits me an error message: "Break on _NSLockError() to debug"

我的假设是：在XCode中，我必须出现一定的这个错误发生的时候调试器停止了。

My assumption is: in XCode i have to appear a certain breackpoint, so that the debugger stops at the point where this error occurs.

我如何做到这一点？

推荐答案

1 /从菜单中选择Build - > Build and Debug

1/ From the menu choose Build -> Build and Debug

2 /点击GDB图标 - 你将会切换到调试器控制台

2/ Click the "GDB" icon - you will be switched to the "Debugger console"

3 /按Control + C中断您的二进制文件。您将获得gdb提示符。

3/ Press Control+C to interrupt your binary. You will get the gdb prompt.

4 /键入b _NSLockError，并在设置断点后继续执行。

4/ type in "b _NSLockError" and continue execution after setting the breakpoint.

(gdb) b _NSLockError
Breakpoint 8 at 0x911db1a9
(gdb) c
Continuing.

5 /您可以与GDB交互，就像从控制台运行一样，即您可以Ctrl + C再次查看当前的断点：

5/ you can interact with GDB just as it was running from console, i.e. you can Ctrl+C again and view current breakpoints:

(gdb) info breakpo
Num Type           Disp Enb Address    What
8   breakpoint     keep y   0x911db1a9 <_NSLockError+9>
