Combining a navigation-based app and a view-based app into one project with tab bar?

[xishuai]

I'm new to coding, and I hope you can help me. I'm using Xcode 4.1, and when I research to problem-solve, the solutions are for a different version.

I successfully built a tableview with all its detail views in one project using a navigation-based template. In another project, I created a map view using a view-based template. Now I need to combine these two projects with a tab bar.

I just read that I should have built the tab base first on a window-based template and deal with the navigation secondarily. Do I have to start over with a window-based template and then code the tab bar part first and navigation controller second? Or should I start fresh with a tab-based template and save some time?

Or, is there an easier way to compile the two projects I already created into a single tab-based application?

I have done kind of a same thing recently. It is right that your rootcontroller should be a UITabBarContoller. In the IB in mainwindow you can set the number of tabs and their UIViewControllers/UINavigationControllers. I think you can do these in navigation based app but you have to change the links between the controllers and the AppDelegate. You may want to start a new window based project. But don't delete anything you have done. You may reuse them

Also watch this tutorial it has been really useful for me.
