I have a container view which contains a number of inner views.
These inner views represent an

I'm a little new to this, so I was wondering if there was an
efficient way for a new inner view to be created
when an object is added to the array, and of course for one to be
delete when an object is removed from
the array. To my understanding, the only message I will get is that
the array *changed*, and I will thus be forced
to completely re-set up my views every time the array changes. Is
this correct? Or is there some sort of
- (void)controllerDidAddObjects:toIndexes: ? Or perhaps I'm
completely thinking about this in the wrong way.
You can always ask the object to which you're bound how many things
you have -- see Graphics Bindings.
See also NSCollectionView.
