This does not appear to be the case. From the NSObject docs: copyWithZone: Returns the receiver. + (id)copyWithZone:(NSZone *)zone Return Value The receiver. Discussion This method exists so class objects can be used in situations where you need an object that conforms to the NSCopying protocol. For example, this method lets you use a class object as a key to an NSDictionary object. You should not override this method.
