UIAlertView代表 [英] UIAlertView Delegates

问题描述

有人可以解释委托给 UIAlertView 的工作原理吗？是自动调用还是我必须调用它？例如：

Can someone explain how the delegate to a UIAlertView works? Is it automatically called or do I have to call it? Eg:

- （void）alertView：（UIAlertView *）alertView clickedButtonAtIndex：（NSInteger）buttonIndex

推荐答案

只要你正确设置UIAlertView的委托属性并实现协议，当用户点击在警报中的按钮上。

So long as you're correctly setting the delegate property of the UIAlertView and implementing the protocol, it will be automatically called when a user clicks on a button in your alert.

请参阅http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIAlertViewDelegate_Protocol/UIAlertViewDelegate/UIAlertViewDelegate.html 查看动作。
