iPhone CoreDataRecipes (IPhone Application Development)

This sample shows you how to do a lot of things, among them using view controllers, table views, and Core Data in an iPhone application. It uses the view controller to manage information, and table views to display and edit data. What is more important, though, is its use of Core Data. Core Data is the way you should think about saving objects and then retrieving them from a persistent store (such as a file on disk), and the sample shows you how to implement a Core Data persistent store.
