Discussion 議論

If the receiver is a suboperation of another progress object, the system invokes the pausingHandler block when pausing the containing progress object.

Special Considerations 特別な注意事項

You’re responsible for pausing any work for the progress object.

You can invoke the pausing handler on any queue. If you must do work on a specific queue, dispatch to that queue from within the pausing handler block.
