The original works with both GC and non-GC, while the version with
autorelease will leak under GC (because the string is never
CFRelease'd). In order to work with both runtimes, either use the
original, or do this:
- (NSString *)uuid
{
CFUUIDRef uuidRef = CFUUIDCreate(NULL);
CFStringRef uuidStringRef = CFUUIDCreateString(NULL, uuidRef);
CFRelease(uuidRef);
return [NSMakeCollectable(uuidStringRef) autorelease];
}
