How do I detect which SKSpriteNode has been touched

Question

I find a similar question, but I am trying to detect and identify which Sprite the user touch, and I don\'t know how to do that. This is my variable:

var sp

First, you need another way to create the sprite, here are a way:

let spriteA = SKSpriteNode(imageNamed: "a")
scene.addChild(spriteA)
let spriteB = SKSPriteNode(imageNamed: "b")
scene.addChild(spriteB)
...and so on...

Now we needs to set a name for the sprite so we can know which node is tapped later. To add a name for a sprite just do this:

spriteNode.name = "name of the sprite"

Putting this code in the above example will look something like this:

let spriteA = SKSpriteNode(imageNamed: "a")
spriteA.name = "a"
scene.addChild(spriteA)
let spriteB = SKSPriteNode(imageNamed: "b")
spriteB.name = "b"
scene.addChild(spriteB)
...and so on...

To detect touches put this into your SKScene subclass:

override func touchesBegan(touches: Set, withEvent event: UIEvent?) {
    let touch = touches.first as UITouch!
    let touchLocation = touch.locationInNode(self)
    let targetNode = nodeAtPoint(touchLocation) as! SKSpriteNode
}

The targetNode is the node you tapped.

If you wants to get the name of the sprite you can use targetNode.name.
