Developing a Static Library and Incorporating It in Your Application in Xcode4

Developing a Static Library and Incorporating It in Your Application

From: http://developer.apple.com/library/ios/#documentation/Xcode/Conceptual/ios_development_workflow/910-A-Developing_a_Static_Library_and_Incorporating_It_in_Your_Application/archiving_an_application_that_uses_a_static_library.html

When you need to develop a static library to use in an application and you have to have separate projects for each product, you can use a workspace to contain both the static library project and the application project. If you do, ensure that you configure the projects in the workspace as described here:

1. In the target that builds the static library, ensure that:

   • The exported headers are in the Project group in the Copy Headers build phase.

   • The Skip Install build setting is set to Yes.

2. In the target that builds the application, ensure that:

   • The User Header Search Paths build setting is set to the recursive absolute path of a directory under which the static library’s header files are stored.

     Important: If you move your static library project directory to a different location in your file system, you must update the value of the User Header Search Paths build setting to reflect the new location of the static library’s header files.

   • The Always Search User Paths build setting is set to Yes.

   • The Skip Install build setting is set to No.

3. In the scheme that builds the application, ensure the scheme also builds the static library for archiving.
