You're working way too hard. Also, your first localPoint= is exactly the wrong way around. It should be:
NSPoint localPoint = [controlView convertPoint:[event locationInWindow] fromView:nil];
that should be all you need to do. As I understand it, a cell's -controlView method might not return the control view reliably, so you are better off using the view passed to the method as a parameter.
All that convertScreenToBase stuff you're doing is superfluous AFAICS.
