Resolving all symbolic links in NSURL

Question

I'm writing a little piece of code in which I should detect if an NSURL contains a symbolic link (i.e., symbolic file components other than the last one should also be detected). To do this, I confront the NSURL itself with the NSURL returned by -URLByResolvingSymlinksInPath. The problem is that this method seems to return all symbolic links in lowercase. Is there another way to solve this problem?

What's the problem with it returning resolved symlinks in lowercase? — Mike Abdullah, Feb 03 '13 at 23:58
Did you try `-[NSString stringByResolvingSymlinksInPath]`? Does it have the same “bug”? — Tricertops, Feb 05 '13 at 12:29

You can traverse symlinks manually:

Detect symbolic link using -[NSFileManager attributesOfItemAtPath:error:] and in key NSFileType search for NSFileTypeSymbolicLink value.
Get destination path using -[NSFileManager destinationOfSymbolicLinkAtPath:error:] and append them.

Repeat this for every path component.

Thanks, this would have been my choice if I didn't notice the bug was resolved! – Nickkk Feb 07 '13 at 16:36

Either I really did something wrong or this bug was fixed with the latest Mountain Lion update. Now all symlinks are correctly resolved.
