Adding Location Information to the App
Working with location data and maps on iOS is relatively simple. By tapping into the provided frameworks, you can build powerful apps very quickly that take location data into account. You expand the MyContactList app with a map that shows all your contacts as well as the user’s location on a map.
To better understand the capabilities available when working with location, the first step is to build a temporary screen to explore the location functions before building the final app. The Map Screen controller is used to provide the location information until it is replaced later in the chapter with an actual map.
