在Swift中将字典对象传递给Objective C协议 [英] Passing dictionary objects to Objective C protocol in Swift

问题描述

我正在尝试使用swift将字典对象传递给Objective C协议.

I'm trying to pass a dictionary object to an Objective C protocol using swift.

协议代码段如下:

@protocol MessageDelegate

- (void)handleNewMessageArrived:(NSDictionary *)messageContent;

@end

这是实现协议的swift类:

and this is the swift class the implements the protocol:

class ViewController: UIViewController, MessageDelegate
{
 ...

 func handleNewMessageArrived(messageContent : NSDictionary!)
 {
  ...    
 }
}

但是构建失败，并且我得到的错误是:

But the build fails, and the error I get is:

" 类型'ViewController'不符合协议'MessageDelegate "

"the type 'ViewController' does not conform to protocol 'MessageDelegate"

我查看了此SO问题，但它处理的是特定对象类型.

I looked at this SO Question but it deals with a specific object type.

我声明\实现委托方法的方式是否存在错误?还是以我认为参数被快速映射的方式?

is there an error in the way I declare\implement the delegate method? or in the way I assume the arguments are mapped in swift?

我是Swift的新手，所以非常感谢您的帮助.

I'm new to Swift so any Help will be much appreciated.

推荐答案

尝试在您的Swift类中实现该方法，如下所示:

Try implementing the method in your Swift class like this:

func handleNewMessageArrived(messageContent: [NSObject : AnyObject]!) {
    // Handle the message
}
