xcode/iphone - 只從命令行調用預處理器？

Question

這可能嗎？基本上，我想調用預處理器，就好像我正在構建我的項目一樣 - 但只是將預處理的文件保存在某處，而不是繼續構建整個項目。

Answer 1

這裏是你的標誌：

-E Stop after the preprocessing stage; do not run the compiler proper. 
    The output is in the form of preprocessed source code, which is 
    sent to the standard output. 

    Input files which don't require preprocessing are ignored.
