But you have written class methods, so instances doesn’t come into it. Seems possible that there’s a fundamental misunderstanding involved here. What you’ve described (a base class that provides a generic interface, with specific implementations in subclasses) is eminently doable - in fact largely the entire point of object-oriented programming - but perhaps you should simply be doing this using straightforward instance methods, not class methods? —Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
