基于响应者链条的事件传递方式

Responder objects—that is, instances of 
UIResponder—constitute the event-handling 
backbone of a UIKit app. Many key objects are also responders, including the 
UIApplication object, UIViewController objects, and all UIView objects (which
 includes UIWindow). As events occur, UIKit dispatches them to your app's 
 responder objects for handling.
