Beginning iOS 5 Application Development

THE MASTER-DETAIL APPLICATION TEMPLATE

Beginning with the iOS SDK 3.2, a new application template exclusive to the iPad became available: Split View-based Application. It enables you to create a split-view interface for your iPad application, which is essentially a master-detail interface. The left side of the screen displays a list of selectable items, while the right-side displays details about the item selected. In iOS 5, Apple has merged the Split View-based Application template with the existing Navigation-based Application template, calling it the Master-Detail Application template. In essence, when your Master-Detail Universal application is run on the iPhone, it will behave just like a Navigation-based application. When it is run on the iPad, it will behave like a Split View-based application.
