Xcode - how to include c library and header file to cocoa project?

cocoa, objective-c, xcode, xcodebuild

Solution

I figured it out.

I point to location of project `a` deployment directory (headers) to Search Path in project settings either:

- as `Header Search Paths`, if used as `<a/a.h>`

- or into `User Header Search Paths`, if used as `"a/a.h"`

As for library I just drag it to Xcode project and set it to refer to library instead of copy.

Problem

How do I add c library to Xcode Cocoa project? Or what is the best option, I don't want to copy them into Cocoa project directory. I have a C project called `a` which compiles into library `a.dylib` and header file `a.h`, the project is located in it's own directory. I want to use this library from my objective-c application in Xcode. How do I add the header file and library to my Xcode project? I can drag the `a.dylib` into `other frameworks` but what do I do with `a.h`?
