在 iPhone 应用程序中添加 2 个以上的代表 [英] Adding More Than 2 Delegates in iPhone App

问题描述

这是一个比我更熟悉 Objective-C 的人可以快速回答的简单问题——如何向一个类添加 2 个以上的代表?

This is a simple question that can be answered fast by someone who's more familiar with Objective-C than I am- how can one add more than 2 delegates to a Class?

澄清一下，我习惯于将委托放在这样的类中:

To clarify, I'm used to putting delegates in classes like this:

@interface ViewController : UIViewController { ...

当我尝试放置两个代表时:

When I try to put two delegates:

@interface ViewController : UIViewController { ...

...该应用程序给出了许多错误，但都没有帮助解决这种情况.

...the app gives many errors, none of which help with the situation.

我需要在代表之间放置一个分隔符，还是可能有两个以上的分隔符?

Is there a separator that I need to put between the delegates, or is it possible at all to have more than two?

提前感谢您的帮助.

推荐答案

实现多个协议的类的正确声明是逗号分隔列表

The correct declaration for a class that implements multiple protocols is a comma separated list

@interface ViewController : UIViewController <UIWebViewDelegate, UITextFieldDelegate>
{ ...
