Receive touch events at SKScene AND SKSpriteNode in SpriteKit

问题

Building a UI with buttons as SKSpriteNode's. Button sprites receive touch events to handle special effects (elastic scaling effects) But I need the SKScene to handle the touch events at the same time to handle UI navigation logic.

How would be possible to both (sprite AND scene) to handle these touch events?
