Xcode——展开文件中的所有宏，而不进行完整的预编译？
我正在尝试阅读一些包含很多宏的代码。而且宏通常是链接在一起的。有没有什么方法可以查看所有宏都已展开的文件版本 - 而无需完全运行预处理器（这也会执行诸如扩展#imports之类的操作）？这确实有助于我阅读代码。
编辑：通常宏是在其他文件中定义的。
I am trying to read some code that has a lot of macros in it. And often the macros are chained. Is there any way to see a version of the file where all the macros have been expanded -- without doing a full run of the preprocessor (which would also do stuff like expand #imports)? This would really help me read the code.
EDIT: Often the macros are defined in other files.

不确定是否有办法在 Xcode 中执行此操作，但您可以使用编译器，特别是 -E 选项，它在预处理后立即停止处理。
将在标准输出上打印所有预处理结果。并将
预处理后的输出转储到 foo.preproc 中。
Not sure if there's a way to do this in Xcode, but you can use the compiler, specifically the -E option, which stops processing right after preprocessing.
will print all the preprocessed results on stdout. And
will dump the preprocessed output into
foo.preproc.据我所知，我的问题的答案是没有办法做到这一点。我能做的最好的事情就是进行完整的预编译，然后搜索文件中在所有 #include 语句之后开始的部分。
As best I can tell, the answer to my question is that there is no way to do it. The best I can do is do a full precompile, then search for the part of the file that starts after all the #include statements.
