CFUUID
CFUUID is available from iOS 2.0. CoreFoundation package (C style API) provide CFUUID. CFUUIDCreate is the method to create the CFUUIDRef and can get an NSString representation of the created CFUUIDRef like :-
CFUUIDRef cfuuid = CFUUIDCreate(kCFAllocatorDefault);
NSString *cfuuidString = (NSString*)CFBridgingRelease(CFUUIDCreateString(kCFAllocatorDefault, cfuuid));
CFUUID is not persisted, every time you call CFUUIDCreate and will get new unique identifier.
