Modifying the City Guide Application

The best way to explain the modal view is to show it in action. For that, we’re going to go back to the City Guide application we built in Chapter 5. We’re going to make some fairly extensive changes to it, so you should make a copy of the project first and work with the copy while you make your modifications. In this section, I’ll show you how to take your code apart and put it back together again in an organized fashion. This occurs a lot when writing applications, especially for clients who have a tendency to change their minds about what they want out of the application in the first place.

Open the Finder and navigate to the location where you saved the CityGuide project; see Figure 6-18.
