- iOS 11.0+
- Mac Catalyst 13.0+
The table view that is attempting to handle the drop.
The drop session object containing information about the data being dragged.
YES if the table view can accept the dragged data or
NO if it cannot.
Implement this method when you want to dynamically determine whether to accept dropped data in your table view. In your implementation, check the type of the dragged data and return a Boolean value indicating whether you can accept the drop. For example, you might call the hasItemsConformingToTypeIdentifier: method of the session object to determine whether it contains data that your app can accept.
If you do not implement this method, the table view assumes a return value of
YES. If you return
NO from this method, the table view does not call any more methods of your drop delegate for the given session.
