iOS Dev Using Objective-C, Part 2: REST and JSON
with expert David Solberg
In this course we go over the basics of what it means to have a RESTful interface. We then review the Objective-C objects and methods we will use to interact with the remote service over http. Next we revise an application to use some basic http methods to download data from a Ruby server. Then we review the JSON information format. JSON objects map to Objective-C strings, numbers, dictionaries and arrays. We'll look at the format so we can predict from the raw data what types of objects we will get from the NSJSONSerialization class. Last but not least we create a custom NSObject subclass to hold JSON data.Course Outline
