ios - Detect touch on child node of object in SpriteKit

Question

I have a custom class that is an SKNode, which in turn has several SKSpriteNodes in it. Is there a way I can detect touches on these child SKSpriteNodes from my game scene?

I'm working in swift

Answer 1

override func touchesEnded(touches: NSSet, withEvent event: UIEvent) {

   let touch = touches.anyObject() as UITouch

   let touchLocation = touch.locationInNode(self)

    if([yourSprite containsPoint: touchLocation])
    {
         //sprite contains touch
    }
}
