No. It's not legal syntax for accessing an ivar in any case - square brackets invoke a method:- [instance method]. Obj-C does not have the concept of private/public/protected methods, unlike C++. Perhaps you could ask is: (A*)b->priv legal? Depends. If priv is @private it is invisible to code other than within the methods of class A itself, so if this code lived inside such a method it would work, otherwise it would not. I don't think the cast makes any difference. But this is not getting to the problem that the OP is having, which AFAICS is unrelated to @private. @private is a Good Thing™ - often worth using. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
