Methods

Name	Description
CanHandleDropSession(UICollectionView, IUIDropSession)	Returns a Boolean value that tells whether the collection view can handle drops from the data in the session.
DropSessionDidEnd(UICollectionView, IUIDropSession)	Method that is called when the drop session ends.
DropSessionDidEnter(UICollectionView, IUIDropSession)	Method that is called when the drop point enters the collection view.
DropSessionDidExit(UICollectionView, IUIDropSession)	Method that is called when the drop point leaves the collection view.
DropSessionDidUpdate(UICollectionView, IUIDropSession, NSIndexPath)	Method that is called when the drop point over the collection view changes.
GetDropPreviewParameters(UICollectionView, NSIndexPath)	Returns the drag preview parameters for the item at the specified index path.
