UISplitViewController and NSRegularExpression
The iPhone and iPod touch have a limited amount of screen real estate. Given their small
screen size, when presenting a drill-down interface, we use a
UINavigationControl-
ler
to swap between a list of items and a detailed view for an item.
The iPad, on the other hand, has plenty of screen space to present both views using a built-
in class called
UISplitViewController
.
UISplitViewController
is an iPad-
only class that presents two view controllers in a master-detail relationship. The master
view controller occupies a small strip on the lefthand side of the screen, and the detail view
controller occupies the rest of the screen.
In this chapter, you will have
Nerdfeed
present its view controllers in a split view controller
when running on an iPad (
Figure 26.1
). We will also make
Nerdfeed
a universal application
and have it continue to use a
UINavigationController
when run on the iPhone.
