I think the confusion here (between the question and the answers) is that the Bar object only contains a *pointer* to the Foo object, not the Foo object itself. In that sense, the Foo is *not* contained within the BAR at all -- the concept of "containing instance" doesn't exist in Obj-C (unlike, say, C++). So, if you want your Bar to be the "parent" of a Foo, and you want the Foo to know its parent, you have to pass the Bar's object pointer as a parameter when setting up the Foo, as others have told you. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
