How would one go about hiding the InstanceVariables in the header for a class like Apple does with many core Cocoa classes?

For example, if you look at NSArray.h, there are no InstanceVariable declarations visible, only methods. How would I do the same in my classes?

NSArray is a class cluster; the arrays you actually use are a subclass of NSArray. Hence why NSArray itself has no instance variables. Check out the ClassClusters tutorial for how to roll your own. – KritTer

Ah… I see. Thanks!
