Http://itunes.apple.com/lookup?id= $id
Use this address to get the app's icon, description, version number, and release notes
For example, request a secret JSON message:

Recall that previous iOS version detection is a client pull server, the service side returns the latest version information and the new instructions, and the server needs to maintain an iOS version update record, in fact, the update function is complicated;
Subsequent iOS versions can be updated with:
1. Only one AppStore ID is maintained in the background
2. Each time the client detects upgrade directly request AppStore, get AppStore version information, and then local determine whether there is a new version, there is prompt update
