Hi,
This may be very basic question. I am curious to know the details.
what was the reason NSNumber conforms to NSCopying protocol.
NSNumber is immutable class, Making a copy of NSNumber object returns the
same reference.
Is there any case where NSNumber returns the new object? if not, then what
is the purpose of conformance to NSCopying protocol.
Regards
Sasikumar JP
