标识同一位置的所有节点-Identifyallnodesatsamelocation

I have a iOS app that draws a grid of sprites on screen. I then have another sprite representing a colour which I can drag and drop over the grid. My question is how do I identify which sprite on the grid it was dragged onto?

我有一个iOS应用程序，可以在屏幕上绘制精灵网格。然后我有另一个表示颜色的精灵，我可以拖放到网格上。我的问题是如何识别它被拖到网格上的哪个精灵?

Ultimately I want to allow a user to drag a colour sprite over another sprite, so I can change the colour, as per the users selection.

最终，我希望允许用户将颜色精灵拖到另一个精灵上，这样我就可以根据用户的选择改变颜色。

The code below only returns the 2nd sprite (the top one) at the location, whereas I need to identify both sprites at that location.

下面的代码只返回位置上的第二个sprite(顶部)，而我需要在那个位置识别两个精灵。

 override func touchesEnded(touches: Set, withEvent event: UIEvent?)
{
    print("tocuhes ended")

    for touch in touches
    {
        let location = touch.locationInNode(self)
        let nodeAtLocation = self.nodeAtPoint(location)

        let nodeName = nodeAtLocation.name

        print("Node Name \(nodeName)")


    }
}

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

    for touch in touches
    {
        let location = touch.locationInNode(self)
        let nodesAtLocation = self.nodesAtPoint(location)

        for node in nodesAtLocation {

            let nodeName = node.name

            print("Node Name \(nodeName)")

        }
    }
}
