iOS获取手机上app信息

在代码中插入一段查询网址即可获取app信息以及版本信息。
查询命令：http://itunes.apple.com/lookup?id=xxxxxxxxx（9位appid数字）

获取设备上所有app (为LSApplicationProxy 对象)

Class LSApplicationWorkspace_class =     objc_getClass("LSApplicationWorkspace");
   NSObject *workspace = [LSApplicationWorkspace_class performSelector:@selector(defaultWorkspace)];
   NSArray *apps = [workspace performSelector:@selector(allInstalledApplications)];
   NSLog(@"apps: %@", apps);

获取版本信息

    [apps[0] performSelector:NSSelectorFromString(@"shortVersionString")]
