Is there perhaps a better way to determine if a view is "key" ?
No, but I believe you should also check that the control view's
window -isKeyWindow or -isMainWindow.
If you are implementing code in an NSCell, then you shouldn't have to
do this. Instead look at the cell's backgroundStyle; if it is
NSBackgroundStyleDark, then you are being drawn in a selected row that
is focused. If it is NSBackgroundStyleLight, then you are being drawn
in a non-selected row, or a selected row that isn't in a
firstResponder tableview.
For views, they will have to check to see if
self.window.firstResponder == self. == is okay, since views aren't
copyable. You may also have to check of self.currentEditor ==
self.window.firstResponder, if you support editing and use the field
editor.

Well "focus" does have a meaning (see -[NSView lockFocus]), but I
figured you didn't mean that here.
Yes, about a week ago I concluded that, unfortunately, Cocoa uses
the word "focus" in two different contexts: "keyboard focus" and
"drawing focus". Someone please correct me if I'm wrong.
You are right -- we frequently toss around both terms. The term
"firstResponder" is for the view that has the first chance of input by
the user; this is the thing that has keyboard focus, and those views
usually draw the focus with NSSetFocusRingStyle(..).
lockFocus is for drawing into a view/image.
