This is normal behaviour. Generally you want to handle "live
resizing", and these notifications allow for that.
"splitViewWillResizeSubviews" happens before the actual resize happens
and "splitViewDidResizeSubviews" happens after.
I'll defer to someone else to answer your other question.

I have a Split View in my U/I. I want to update some controls

implemented
- (void)splitViewDidResizeSubviews:(NSNotification *)aNotification
thinking it would be invoked after the user was done resizing (i.e.,
after the mouse up event). However, I receive this notification
repeatedly while moving the divider. The same is true for:
- (void)splitViewWillResizeSubviews:(NSNotification *)aNotification
which also receives repeated notifications while the divider is moved.
Is this expected/normal behavior for Will and Did notifications?
(i.e. to be notified while the doing is happening and either at the
outset and the conclusion )?
If so, what then is the functional difference between Will... and
Did... ?
Also, if I want to know when the user has completed the divider
movement, how would I find that out? I suspect I'd need to subclass
NSSplitView method that handles the mouse events...
