I was looking for a similar solution as this but NSCollectionView doesnt have a similar layout methods.
Any hints ?

Can't you use the scroll view to do that? – Volker Feb 15 '14 at 10:25

@Volker I am already using that for NSTableView but NSScrollView has only one notification `boundsDidChange` which alone is not enough to check if it has reached the end. Atleast I am not able to figure it out ... – user88975 Feb 15 '14 at 11:32

1But you can check the bounds and determine whee the document view got scrolled to?! – Volker Feb 15 '14 at 19:36

@Volker I was looking for some delegates as in iOS. Not quite used to Mac app programming yet :D That should do thanks ! – user88975 Feb 16 '14 at 07:04

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.
