获取iOS的私有API方法的签名 [英] Getting signatures of private API methods for iOS
问题描述
我知道SpringboardService包含许多私有API（例如：SBGetApplicationState，SBDimScreen等）。我使用nm工具获得了这些方法的列表。
I know that SpringboardService contains a lot of private API's (as example: SBGetApplicationState, SBDimScreen etc). I got the list of these methods using "nm" tool.
我想找到一个工具，它可以让我获得这些私有API方法的签名。据我所知，SBGetApplicationState是一个C调用（vs Objective C方法）。因此，我不确定是否可以在不拆卸和其他手动操作的情况下恢复签名。但是，我希望至少存在半自动化过程。
I want to find a tool which will let me get signatures for these private API methods. As I understand SBGetApplicationState is a C call (vs Objective C method). So I am not sure whether it's possible to recover signatures without disassembling and additional manual actions. However, I hope that at least semi-automated process exist.
几个注释：
a）我有看到这个链接（iOS运行时私有标题）：
https://github.com/nst / iOS-Runtime-Headers
a) I have seen this link (iOS Runtime private headers): https://github.com/nst/iOS-Runtime-Headers
它只包含Objective C标头。
It contains only Objective C headers.
b）我看过这个链接（SpringBoard.app/MIG子系统）
http://iphonedevwiki.net/index.php/SpringBoard.app/MIG_subsystem
b) I have seen this link (SpringBoard.app/MIG subsystem) http://iphonedevwiki.net/index.php/SpringBoard.app/MIG_subsystem
It包含一些有趣的信息，但文档有点过时（对于iOS 3.1-4.2）
It contains some interesting information, but the documentation is a little bit outdate (for iOS 3.1-4.2)
c）我正在做研究，我不打算提交AppStore的任何应用程序。我很清楚基于私有API使用的AppStore拒绝
c) I am doing a research and I don't plan to submit any application to AppStore. I am well aware of AppStore rejections based on usage of private API's
推荐答案
- 您对C函数的假设很遗憾 - 你不能自动获得他们的签名。
- 但是，你可以用Objective-C消息做到这一点 - 看看 class-dump （或者更好， class-dump-z ）。
- Your assumption about C functions is unfortunately correct -- you can't automatically get their signature.
- However, you can do this with Objective-C messages -- have a look at class-dump (or, even better, class-dump-z).
