Window and Views
Windows and views are the visual components you use to construct the interface of your iPhone application.Windows provide the background platform for displaying content but views do most of the work of drawing that content and responding to user interactions. Although this chapter covers the concepts associated with both windows and views, it focuses more on views because of their importance to the system.
Because views play such a vital role in iPhone applications, there is no way to cover every aspect of them in a single chapter. This chapter focuses on the basic properties of windows and views, their relationships to each other, and how you create and manipulate them in your application. This chapter does not cover how views respond to touch events or draw custom content.
