could you tell me please - which object and which method can i use to fetch information about installed applications on OSX with objective c or macruby?

推荐答案

如果要列出所有GUI应用程序，则可以使用参考.

If you meant to list all of GUI apps, you can use Launch Services. For the list of functions, see the reference.

请勿手动列出 .app 捆绑包！！系统已完成此操作，您只需要查询即可. 在

Do not manually list .app bundles! It's already done by the system, and you just have to query it. There is a command-line program called lsregister at

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister

可用于获取启动服务数据库的详细转储.该工具有时会很有帮助， 但不要在运输程序中依赖它，

which can be used to get the detailed dump of the Launch Service database. This tool is sometimes helpful, but don't depend on that in a shipping program,
