f you are on OS X 10.8 or iOS 6 you can use the new NSUUID class to generate a string UUID, without having to go to Core Foundation:

NSString *uuidString = [[NSUUID UUID] UUIDString];
// Generates: 7E60066C-C7F3-438A-95B1-DDE8634E1072
But mostly, if you just want to generate a unique string for a file or directory name then you can use NSProcessInfo's globallyUniqueString method like:

NSString *uuidString = [[NSProcessInfo processInfo] globallyUniqueString];
// generates 56341C6E-35A7-4C97-9C5E-7AC79673EAB2-539-000001F95B327819
It's not a formal UUID, but it is unique for your network and your process and is a good choice for a lot of cases.
