I just figured this out yesterday.  It wasnt obvious from the
limited documentation.

First you have to create your own class by using the subclass item in
the Class window.  Which class it is a subclass of depends on what you
want to do with it.  

Then create an instance of your class and add an outlet in the Class
Inspector which will be used to name the scrollview (getting the right
display up for this can be a trick).

Then make a connection from this outlet by going to the connections
display, selecting the outlet and control dragging from your class
instance to the ScrollView.

Then unparse your class and edit the source to add methods that have
access to the ScrollView via your named outlet.  I havent figured out
when exactly the outlet is set to the object it is connected to.
