目标C：在哪里可以找到<进程ID>在gdb中？ [英] Objective C: Where to find <process id> in gdb?

问题描述

我试图用NSZombie来调试我的程序。调试器确实返回了带有问题的实例地址，但我不确定在哪里获得运行命令'shell malloc_history

I am trying to debug my program using NSZombie. The debugger did return me the address of the instance with the issue, however I am not sure where to obtain the pid which is required to run the command 'shell malloc_history

所需的pid有人建议我在这种情况下使用的正确pid是什么？我尝试了3298和3298：707，他们都没有工作。

Can anyone advise me on what is the correct pid to use in this case? I tried 3298 and 3298:707 and they both didnt work. Appreciate any help here.

推荐答案

malloc_history仅适用于模拟器。你的日志说你正在设备上做这件事。

malloc_history works only in simulator. Your logs say that you are doing it on device.
