I am writing a chess program that stores all the pieces in an NSMutableArray with [NSNull null] representing empty spaces. I just found out about NSPointerArray and was wondering if I should switch over to that instead. Basically, what are the pros/cons of using an NSMutableArray with [NSNull null] values vs an NSPointerArray?

If you are putting objects in the
NSMutableArrayas well, say the chess pieces, stay withNSMutableArray. Also there is really no reason not to use[NSNull null], really not much different that putting a NULL in aNSPointerArray.If you are concerned about performance measure before making any change.
