ios - 快速、objective-c 协议(protocol)实现

Question

还在努力适应swift，但是由于我的obj-c知识接近于0，一直没能实现这个SocketRocket协议(protocol)。任何帮助将不胜感激

这是我尝试实现的 obj-c 委托(delegate)

@protocol SRWebSocketDelegate <NSObject>

// message will either be an NSString if the server is using text
// or NSData if the server is using binary.
- (void)webSocket:(SRWebSocket *)webSocket didReceiveMessage:(id)message;

@optional

- (void)webSocketDidOpen:(SRWebSocket *)webSocket;
- (void)webSocket:(SRWebSocket *)webSocket didFailWithError:(NSError *)error;
- (void)webSocket:(SRWebSocket *)webSocket didCloseWithCode:(NSInteger)code reason:(NSString *)reason wasClean:(BOOL)wasClean;

@end

我希望这是实现它的正确方法；这不是……
我得到 'SocketDelegate' does not conform to protocol 'SRWebSocketDelegate'

class SocketDelegate:UIViewController, SRWebSocketDelegate{
    let socket:SRWebSocket! = SRWebSocket()

    override func loadView() {
        self.socket.delegate = self
    }    

    func didReceiveMessage(message:AnyObject){

    }
}

Answer 1

答案是:

func webSocket(webSocket: SRWebSocket!, didReceiveMessage message: AnyObject!)

看

Functions in Swift Reference Book

Obj-C webSocket:didReceiveMessage 中的方法名是这样翻译的，比如第一部分是方法名，其他部分是外部参数名(didReceiveMessage)。另请注意，id 变为 AnyObject 并且 Obj-C 引用被翻译为 ! 为隐式解包选项(这不再是真的，隐式解包选项由于添加到 Obj-C 声明的属性，现在很少见了)。
