The interface for initiating drags from a collection view.
- iOS 11.0+
- Mac Catalyst 13.0+
Implement this protocol in the object that you use to initiate drags from your collection view. The only required method of this protocol is the
collection method, but you can implement other methods as needed to customize the drag behavior of your collection view.
Assign your custom delegate object to the
drag property of your collection view.
