UINavigationController
In Chapter 7 , you learned about UITabBarController and how it allows a user to ac-
cess different screens. A tab bar controller is great when you have screens that don't rely on
each other, but what if you want to move between related screens?
For example, the Settings application has multiple related screens of information: a list of
settings (like Sounds ), a detailed page for each setting, and a selection page for each detail.
This type of interface is called a drill-down interface .
In this chapter, you will use UINavigationController to add a drill-down interface
to Homepwner that lets the user view and edit the details of a BNRItem . ( Figure 11.1 ).
