URLCache demonstrates how to download a resource, store it in the data directory, and use the local copy. Very useful for anything you want your app to do on the Web. It also includes a framework for asynchronous processing. If you need to download a lot o’ data when the application starts, this sample shows you how to tell your app to start a download and then go off and do other things until the download completes. It also includes an activity-indicator view that tells the user your application is actually at work, and not on a lunch break.
