嗨，我一直试图做这个很长一段时间，我的问题是当我点击形状1（你会理解你是否读过代码）它什么都不做什么时它应该打印“Hello”和它不是。我已经尝试过更改图像，但这并没有改变任何东西。但是当我使用if语句并离开println时，当我点击它时会打印你好。 在此先感谢！

如果您有多个重叠节点，可以通过搜索self.nodesAtPoint函数内的节点来检测特定节点上的触摸。
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
for touch in touches {
let location = touch.locationInNode(self)
for node in self.nodesAtPoint(location) as [SKNode]{
if node.name == "shape1" {
println("Shape1 touched")
}
}
}
}
