iOS模拟器应用程序的终端命令行调试? [英] Terminal command-line debug of iOS Simulator apps?

问题描述

是否可以在Mac OS X的终端命令行中使用GDB或LLDB来调试在iOS模拟器上运行的应用程序? (例如，不是从Xcode的GUI或控制台中，而是使用外部命令行或进程).如果可以，怎么办?

Is it possible to use GDB or LLDB from the Terminal command-line under Mac OS X to debug apps running on the iOS Simulator? (e.g. not from within Xcode's GUI or console, but using an external command-line or process). If so, how?

推荐答案

您需要已经在模拟器的Springboard中安装了该应用；您无法从Xcode在模拟器中启动该应用，然后期望能够将gdb的命令行实例附加到该应用.

You'll need to have the app already in the simulator's Springboard; you can't launch the app in the simulator from Xcode and then expect to be able to have a command line instance of gdb attach to it.

所以:

1. 运行iOS模拟器，并且已经将您的应用程序加入其中.
2. 在终端窗口中:

    % gdb
    ...
    (gdb) attach --waitfor 'Name Of Your App'

1. 从模拟器Springboard启动您的应用.
2. gdb应该在执行 main()之前附加到进程.因此，您可以设置一些断点或其他任何内容.然后:

1. Launch your app from the simulator Springboard.
2. gdb should attach to the process before main() is executed. So you can set some breakpoints, or whatever. Then:

    (gdb) continue

lldb的过程类似:

    % lldb
    (lldb) process attach -n 'Name Of Your App' --waitfor
    <launch your app in the simulator>
    (lldb) continue

我不确定为什么要这样做，但是作为老命令行gdb(和dbx)，我会很感激. :-)

I am not sure why you'd want or need to do this, but as an old command line gdb (and dbx) guy, I can appreciate it. :-)
