Hi All,
A long time back, I remember reading something about the way in which copy and mutableCopy are implemented. I think basically it said that:
someObject = [someOtherObject copy];
or
someObject = [someOtherObject mutableCopy];
Wouldn’t necessarily allocate any extra data storage. I’ve been searching for it to refresh my memory, but I can’t see to find it anywhere. Does anyone know if this document or something like it exists somewhere?
Thanks a lot
Dave
