Discussion

Whenever possible, register classes or nib files for your items instead of using this property. For more information, see Creating Collection View Items.

Subclasses can override this method if the collection view items are not generated from a prototype or if the prototype view needs to be modified. The subclass is responsible for setting the view and representedObject of the new collection view item.
