The Pickers Application

This chapter's application, Pickers, will feature a tab bar. As you build Pickers, you'll change the default tab bar so it has five tabs, add an icon to each of the tab bar items, and then create a series of content views and connect each view to a tab.

The application's content views will feature five different pickers:

• Date picker: The first content view we'll build will have a date picker, which is the easiest type of picker to implement (see Figure 7–2). The view will also have a button that, when tapped, will display an alert that shows the date that was picked.

Figure 7–2. The first tab will show a date picker.

• Single-component picker: The second tab will feature a picker with a single list of values (see Figure 7–3). This picker is a little more work to implement than a date picker. You'll learn how to specify the values to be displayed in the picker by using a delegate and a data source.
