Overview
NSCollectionViewItem class is a controller that manages the relationship between a compound view and the model object that provides its content. Instances of this class are replicated in a NSCollectionView.
Important: In Mac OS X v10.5, the superclass of the NSCollectionViewItem class was NSObject. In Mac OS X v10.6 and later, NSCollectionViewItem is now a subclass of NSViewController. This change was made to improve how the view is replicated within the NSCollectionView. NSCollectionViewItem remains binary compatible with the previous implementation and unarchiving is correctly handled.
