Generally you subclass the control and implement whatever data
association you want.

Is there a Cocoa equivalent to Carbon's Get|SetControlProperty()
family of functions? For those not familiar these functions let you
associate user data with controls. I've never really used this for
much, but it is very useful for storing a pointer to a C++ object
representing the control in a UI framework, for example.
It would be great to be able to do this for NSViews but I haven't
been able to find any equivalent. Are there any ingenious ways that
you might be aware of so I could bolt this on to NSView?
I'm trying to avoid setting up a map from NSViews to UI framework
objects, but I suspect it will be inevitable. Not really a big deal,
but less hassle to be able to associate the data directly so that
would be a preferable solution.
