我想在用户触摸屏幕时获取屏幕坐标。我尝试touchesBegan方法，但当我使用NSSet作为参数时，我得到一个错误。任何人都可以指导我在哪里弄错了如何解决这个问题。

Thanks in advance...

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    let touch = touches.anyObject()! as! UITouch
    lastPoint = touch.locationInView(self)
}

Error: Overriding method with selector 'touchesBegan:withEvent:' has incompatible type '(NSSet, UIEvent)'

错误：使用选择器'touchesBegan：withEvent：'的覆盖方法具有不兼容的类型'（NSSet，UIEvent）'
