This is especially true of one framework in particular — the UIKit framework, the heart of the user interface.
In this chapter, I'm going to lead you on a journey through most of the iPhone's user interface architecture — a mostly static view that explains what the various pieces are, what each does, and how they interact with each other. This will lay the groundwork for developing the ReturnMeTo application's user interface, which you get a chance to tackle in Chapter 5. After that's done — but before you start major coding — I'll take you on a similar tour of the iPhone application runtime environment — the dynamic view of all the pieces working together when, for example, the user launches your application or touches a button on the screen.
