XCode Project: how to build sub-projects as static libraries?

Question

I need to build sub-projects as static libraries, not too sure how I should do it, should I:

1. Compile all sub-projects one by one (or compile the main project once?)
2. Find .a files for sub-projects in products folder, copy them to main project
3. copy all .h files for sub-projects into a folder in main projects
4. remove all sub-projects

are the above steps correct?

Also, do I need to compile them in release(or debug) mode, and for simulator and device respectively?

Thanks!

No, you don't need to do any of that because Xcode will do it all for you...

Basically, just drag the library project in, set the dependencies and be done: See this page for details.
