This sample illustrates how to use the UISplitView control for iPad. It utilizes a main split view controller that manages a master view and a set of child views. When an item on the master view is clicked, it raises and event that the main split view controller (MainSplitView) listens for and then notifies the detail view controller accordingly. This pattern should generally be used when implementing the UISplitViewController because it decouples the child views from each other and represents an architecturally resilient design.
