Adding an xcode project into another xcode project

Question

I came across many other SO question but could not found the answer what i needed.

So heres my problem.

I have created a simple app that just shows the google map and shows my current location.

and then I have created another TabBar based application. Now how I will include that map application to my new TabBar based application. And when I select the tab the map project should show its data. means the map should be shown.

How this could be achieved??

so by creating a workspace i will be able to add the map project, i have to then use the same normal procedure to load the tab..that we do in an appllication — Ajeet Pratap Maurya, Dec 20 '11 at 11:43
