Bear in mind that the typical purpose of a ControlRef in Carbon is to
keep track of an associated wrapper object (or other extended data).
In Cocoa, NSControl already is that object. The way to extend an
object is to subclass it and add whatever ivars you need. So there
would appear to be no need for an equivalent to a ControlRef in the
Carbon sense.
What are you trying to do? Better advice might be available knowing
that.

Hi,
In Carbon you can tie a 32 bit value to a control with
SetControlReference. Is there an equivalent method in NSControl? I
looked around in the header files but couldn't find anything
(NSControl, NSView, NSResponder, NSObject).
thanks
Jeff
