If you built a GData static library, make sure the library is listed in the “Link Binary With Libraries” section under the “Build Phases” tab for your target.

If you dragged all of the GData source files into your project, make sure they are all listed in the “Compile Sources” section under the “Build Phases” tab for your target.
