第一种实现方法
#######define APP_URL @"http://itunes.apple.com/lookup?id=你程序的appId"会得到以下返回数据:

}
version 对应info.plist文件里的“Bundle versions string, short”字段是在appstore上的。
“Bundle version”字段,是调试版本号,不是显示在appstore上面。
获取appstore最新的版本号
NSString *appVersion = [infoDic objectForKey:@"version"];
取得本地程序的版本号
NSString *localVersion =[localDic objectForKey:@"CFBundleShortVersionString"];
通过比较决定是否版本更新。
