Best way to get different events for a button mouseDown and mouseUp?

I have a need for some buttons that need to notify my code on both the "mouse down" AND the "mouse up". It looks like one way to do this is to make a subclass of NSButtonCell and override startTrackingAt:inView: and stopTracking:at:inView:mouseIsUp:, and also subclass NSButton and call setCellClass: to associate my button cell class with the button. Then I'd store selectors that the button cell would invoke, and hook up a pseudo "action" for mouse up and mouse down.

Is this the preferred way to do this? It seems like there ought to be something simpler, but I don't see it.....
