推荐答案

UIButton 不会使用委托设计模式。没有 UIButtonDelegate 协议，也没有 UIButton 声明委托属性。

UIButton does not make use of the delegation design pattern. There is no UIButtonDelegate protocol nor UIButton declares a delegate property.

UIButton 通过从UIControl 将动作消息发送到目标对象。

UIButton uses the Target-Action design pattern through the methods inherited from UIControl to send action messages to a target object.
