Discussion 解説

This method is invoked when the drop has been accepted by the destination and the destination, in the case of another Cocoa application, invokes the NSDraggingInfo method namesOfPromisedFilesDropped(atDestination:). For long operations, you can cache dropDestination and defer the creation of the files until the draggedImage:endedAt:operation: method to avoid blocking the destination application.
