问题描述

如何读取用户设置的环境变量？

How could I read an environmental variable that a user has set?

我是Mac（可可）台式机开发的新手，我正在构建一个我可以用来访问亚马逊的s3服务的小工具。

I'm new to desktop development on the Mac (cocoa), and I am building a little tool that I can use to access amazon's s3 service.

我在.bash_profile中设置了环境变量，但是无论用户在哪里输入它，我都希望它能够正常工作（.bashrc，.bash_profile或.profile等）。

I set my environmental variables in my .bash_profile, but I want this to work regardless of where the user entered it (.bashrc, .bash_profile or .profile etc).

推荐答案

查看环境方法。它返回环境的NSDictionary，例如对于PATH

Look at the environment method on a NSProcessInfo. It returns a NSDictionary of the environment so e.g. for PATH

NSString* path = [[[NSProcessInfo processInfo]environment]objectForKey:@"PATH"];
