I have a static C library compiled with arm7-gcc and i want to use it in my iOS project. i added it to project but i can't figure out how to use it.
回答1:
After adding the library to the project and including the header in your application codeб there is a second step. That step is letting the Xcode project know where the header file/files is/are. You do this by editing the "User Header Search Paths" build setting with the path to the header files.
