iPhone Development: Importing from a .m file to another

I need to import functions from .m file to another .m file. If it matters, the first .m file is abc开发者_StackOverflow中文版.m and the second one is bca.m

Thanks a lot.

# import "bca.h"

Import the header, not the implementation.

Add

#import "abc.h"

To the top of bca.m.
