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"];
