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 iPhone application. In the chapter entitled [[Working with Files on iOS 4 (iPhone)|Working with Files on iOS 4]]we looked at creating files and reading and writing data from within an iOS application. In this chapter we will look at another form of data persistence on the iPhone using a more object oriented approach known as archiving.
