How is it possible to detect in NSCollectionView when the last item is visible on scrolling ?
I was looking for a similar solution as this but NSCollectionView doesnt have a similar layout methods.
Any hints ?
回答1:
It is possible to get noted when the scroll view has scrolled by registering for boundsDidChange notification of the document view as described here Callbacks When an NSScrollView is Scrolled? .
That way one can check which part of the content of the collection view is displayed.
