目标C：多名代表 [英] Objective C: Multiple delegates

问题描述

我很好奇，如何以及如何使控制器成为两个不同对象的委托。

这是允许的还是Java中的多重继承？假设我想有一个控制器响应：< UIAccelerometerDelegate> 和 < CLLocationManagerDelegate>

头文件会是这样吗？

  @interface MainViewController：UIViewController< UIAccelerometerDelegate> AND< CLLocationManagerDelegate> {
  

解决方案

实际上，它工作得很好。声明你的界面如下：

  @interface MainViewController：UIViewController< UIAccelerometerDelegate，CLLocationManagerDelegate> 
  

然后从两个委托界面实现方法。

I am curious if and how to make a Controller be the delegate for two different objects.

Is this allowed or is this like multiple inheritance in Java?

Suppose I wanted to have one controller that responded to: <UIAccelerometerDelegate> and <CLLocationManagerDelegate>

Would the header file look like this?

@interface MainViewController : UIViewController <UIAccelerometerDelegate> AND <CLLocationManagerDelegate> {

解决方案

Actually, it works quite well. Declare your interface like this:

@interface MainViewController : UIViewController <UIAccelerometerDelegate, CLLocationManagerDelegate>

and then implement the methods from both delegate interfaces.
