ios 输出预处理后的文件

On the command line,

gcc -E foo.m

will show you the preprocessed output (just as it does for normal C/C++ files). Of course, this will also expand any

#include

or

#import

statements you may have in your code.

From within Xcode:

Xcode 3: Select the file, then Build → Preprocess.

Xcode 4: Select the file, then Product → Generate Output → Generate Preprocessed File.

Xcode 5: Product → perform action → Preprocessed File.
