Tilde-based Paths in Objective-C

问题:

In Objective-C, how do I go about converting tilde-based pathnames to full pathnames? That is, I'd like to convert from ~/sandbox to /Users/TheBobs/sandbox.

回答1:

Use NSString's stringByExpandingTildeInPath: method.

There are also several other methods that make it easy to work with paths.
