If instance variables belong to an instance of a class, class variables would belong to an instance of a metaclass, I should think. But my experience with the Objective-C metaclass tells me that this is unlikely.
I'm wondering what
I found a discussion about it here: http://lists.apple.com/archives/objc-language/2008/Feb/msg00021.html
Nope, it's not possible. There is no compiler support, and there is no runtime support;
class_getClassVariable(cls, name)merely calls
If it were possible, it likely would not give you a new variable on each subclass anyway. Objective-C's metaclasses are not quite first- class enough for that to work well.
