4.0. Introduction
A table view is simply a scrolling view that is separated into sections, each of
which is further separated into rows. Each row is an instance of the
UITableViewCell class, and you can
create custom table view rows by subclassing this
class.
Using table views is an ideal way to present a list of items to users. You can embed images, text, and other objects into your table view cells; you can customize their height, shape, grouping, and much more. The simplicity of the structure of table views is what makes them highly customizable.
A table view can be fed with data using a table view data source,
and you can receive various events and control the physical appearance of
table views using a table view delegate object. These are defined,
respectively, in the UITableViewDataSource and UITableViewDelegate protocols.
Although an instance of UITableView subclasses UIScrollView, table views can only scroll
vertically. This is more a feature than a limitation. In this chapter, we
will discuss the different ways of creating, managing, and customizing
table views.
