问题描述
我正在尝试调用 ptrace 上的函数，如此 ptrace（PT_DENY_ATTACH，0,0,0）; 但是当我尝试使用
#include< sys / ptrace.h> 导入它时，Xcode会给我一个错误'sys / ptrace.h'找不到文件。我错过了什么，我是否需要导入一个库，或者这在iOS上根本不可用？
I'm trying to call a function on ptrace like thisptrace(PT_DENY_ATTACH, 0, 0, 0);But when I try to import it using #include <sys/ptrace.h>Xcode gives me an error 'sys/ptrace.h' file not found. Am I missing something, do I need to import a library or is this simply unavailable on iOS?
推荐答案
这里的问题是Xcode正在将其SDK基本路径添加到所有系统头路径（例如，/Applications / Xcode.app / Constate / Developer / Printers / iPhoneOS.platform / Developer / SDKs / iPhoneOS9.0.sdk / usr / include /）。不幸的是，ptrace.h不存在，但可以在/ usr / include / sys /中找到。因此，要解决此问题，您需要将include语句更改为：
The problem here is that Xcode is prepending its SDK base path to all system header paths (e.g., /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.0.sdk/usr/include/). Unfortunately, ptrace.h is not there but is found in /usr/include/sys/. So, to solve this, you need to change your include statement to be:
#include </usr/include/sys/ptrace.h>
我不知道为什么ptrace.h不包含在SDK中，而是你正在寻找的功能当它在手机上运行时可以正常工作。
I have no idea why ptrace.h is not included in the SDK but the functionality you're looking for does work when it's running on the phone.
更新虽然这确实允许您使用ptrace功能，但上传到Apple会产生申请被拒绝的原因是：
Update: While this does allow you to use the ptrace functionality, uploading to Apple will result in app rejection due to:
Non-public API usage:
The app references non-public symbols in <app name>: _ptrace
