copyis just short forcopyWithZone:, using the default zone.it's rare that you would call
copyWithZone:directly, although defining/implementing it is required in order to adopt@protocol NSCopying. so you would normally seecopyWithZone:only within an implementation ofcopyWithZone:. similarly, you would typically avoid implementingcopy, and just let the default implementation ofcopycall throughcopyWithZone:.
