Changes

In the previous chapters of this book we have looked at some basic file and directory handling operations that can be performed within an iOS 4 iPad application. In the chapter entitled [[Working with Files on the iPad with iOS 4 (Xcode 4)|Working with Files on the iPad with iOS 4]] we looked creating files and reading and writing data from within an iPad application. In this chapter and the next few chapters we will look at some more advanced iPad data storage strategies. One other form of data storage on the iPad, and the subject of this particular chapter, involves data persistence using a more object oriented approach known as archiving.
