当我收到此错误时,我正在尝试创建一个新的覆盖功能:方法不会覆盖它的超类中的任何方法
我已经尝试删除覆盖部分,但这只会给我一个错误。
override func touchesBegan(touches: NSSet!, withEvent event: UIEvent!) {
let touch : UITouch! = touches.anyObject() as! UITouch
location = touch.locationInView(self.view)
person.center = location
}
override func touchesMoved(touches: NSSet!, withEvent event: UIEvent!) {
let touch : UITouch! = touches.anyObject() as! UITouch
location = touch.locationInView(self.view)
person.center = location
}
答案 0 :(得分:5)
正确的方法签名是:
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
}
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
}
