ios - Polidea 的 iOS Class Guard 成功，但无法区分差异

Question

我正在开发一个静态库，并使用 Polidea 的 iOS Class Guard 来混淆我的静态库。我按照步骤在项目的根路径中下载 obfuscate_project，更改其中所需的名称，最后在终端中运行 bash obfuscate_project。我收到一条消息，说我的构建成功，但我找不到我的symbols.h 文件。我还注意到生成了一个构建文件夹。我的问题是，混淆真的发生了吗？如果是这样，我该如何检查？混淆的项目是否在我的构建文件夹中？

PPiOS-Rename 的文档(iOS Class Guard 的一个分支)explains how to do it :

To verify that your app has been obfuscated, use the nm utility, which is included in the Xcode Developer Tools. Run:

nm path/to/your/binary | less

This will show the symbols from your app. If you do this with an unobfuscated build, you will see the orginal symbols. If you do this with an obfuscated build, you will see obfuscated symbols.

Note that nm will not work properly after stripping symbols from your binary. You can use the otool utility if you need to check for the Objective-C symbols after stripping.

otool will show unneeded information, but it can be filtered using grep and awk to only show symbols:

otool -o /path/to/your/binary | grep 'name 0x' | awk '{print $3}' | sort | uniq
