The StoreSearch app
One of the most common things that mobile apps do is talking to a server on the
internet. It’s beyond question: if you’re writing mobile apps, you need to know how
to upload and download data.
In this lesson you’ll learn how to do HTTP GET requests to a web service, how to
parse JSON data, and how to download files such as images.
You are going to build an app that lets you search the iTunes store. Of course, your
iPhone already has apps for that (“App Store” and “iTunes Store” to name two), but
s the harm in writing another one?
Apple has made a web service available for searching the entire iTunes store and
you’ll be using that to learn about networking.
