When you create a new project with Xcode, you can choose to create a library for iPhone OS, and Xcode will create a project for a static library for iPhone OS. Once you created the project, you need to import the files you already have, or paste the code in the files Xcode created for you.

Create two different Xcode projects; in one you put the code for the application, and in the other you put the code of the library.
When you compile the code for the application, you add a reference to the library you compiled from the second project.
