Getting an iOS application's “~/Library” path reliably

问题

This Apple tech note:

http://developer.apple.com/library/ios/#qa/qa2010/qa1699.html

suggests storing "internal" user documents in a subdirectory off of ~/Library. But I can't find one of the pre-created search domains that would get me this. What's the best/most correct/least likely to ever break way of constructing this path?

Thanks.

回答1:

The correct way is

NSString* path;
path = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES)[0];

However, [@"~/Library" stringByExpandingTildeInPath] also works.

Swift 3:

let path = NSSearchPathForDirectoriesInDomains(.libraryDirectory, .userDomainMask, true)[0]

回答2:

You can also try this:

[NSHomeDirectory() stringByAppendingString:@"/Library"]
