-isEqual: equals '==' ?

 Is -isEqual: the same as '==' ?
 Since -isEqual: is defined in NSObject and '==' is in compiler,
 they seem not the same.
Then in NSDictionary, which one does it use to get the object by comparing key ?
 -isEqual: or '==' ?
 From Apple's document, overriding -isEqual: requires overriding -hash.
 Does it apply in GNUstep ?

 Thanx a lot
