ios - 检测 SKNode 上的触摸(快速)

Question

我已经创建了一个容器节点来放入我所有需要一键移动的 SKSpriteNodes，我可以在 iOS 8 中正常检测到它们的触摸，但在 iOS 7 中我只能检测到我的主节点上的触摸以及何时我触摸了一个位于容器节点中的 SKSpriteNode，但没有任何反应。我该如何解决这个问题？

let lvlsNode = SKNode()



override func didMoveToView(view: SKView) {

            self.addChild(lvlsNode)

            axe = SKSpriteNode(imageNamed:"axe")
            axe.anchorPoint = CGPointMake(1, 0)
            axe.size = CGSizeMake(axe.size.width/1.4, axe.size.height/1.4)
            axe.position = CGPointMake(0+screenWidth/7, shield.position.y-shield.size.width*1.4)
            axe.zPosition = 12
            axe.name = "axe"
            lvlsNode.addChild(axe)
}
 override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
        /* Called when a touch begins */

        for touch in (touches as! Set<UITouch>) {
            let location = touch.locationInNode(self)
            let node = nodeAtPoint(location)

          if node.name == "axe" { 
             // do something.... this work in iOS8 but not in iOS 7.1
           }

Yournode.name = "nodeX"

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
   let touch = touches.first as UITouch!
   if atPoint((touch?.location(in: self))!).name == Yournode.name {
       //Your code
   }
}
