This course demonstrates the fundamental techniques used for downloading, reading and writing data in iOS apps. You’ll learn how to download data from an XML web service, parse it and display it in your app. You’ll also see how to perform the same task with a service that serves JSON data. Techniques for storing data locally on an iOS device are covered. These include archiving custom objects as well as reading and writing objects to and from property lists. You will also learn how to use the NSUserDefaults class to read and write simple data such as user preferences. All apps use data of some kind and this course will teach you the fundamental skills you need to get started working with data on the iOS platform. Follow along as we build an iPhone app from scratch and add new functionality in each module.
