How to fetch application icon and application description from iTunes store?
How 开发者_Go百科could I fetch application icon and application details from iTunes store if I have app id?
I believe there is a way to retrieve at least some icons via one of the many App Store RSS feeds, perhaps more easily via a custom feed. I've not tried this method, but I know that at least some apps and websites use them that way.

You can retrieve it all by requesting XML information from the App Store. Dan Grigsby wrote about it about a year ago:

Part 2 explains how to send a query for a specific app using the app ID. The article doesn't provide code for doing it in iOS, but it's very straightforward once you know what to ask for.
