Question

仍然试图习惯swift，但由于我的obj-c知识接近0，我无法实现这个SocketRocket协议。任何帮助将不胜感激

这是我尝试实施的obj-c代表

@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

我希望这是实施它的正确方法;它不是......
我得到＆＃39; SocketDelegate＆＃39;不符合协议＆＃39; SRWebSocketDelegate＆＃39;

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!)

见

Functions in Swift Reference Book

Obj-C webSocket:didReceiveMessage中的方法名称被翻译，例如第一部分是方法名称，其他部分是外部参数名称（didReceiveMessage）。另请注意，id变为AnyObject，Obj-C引用被!翻译为隐式解包的选项（这不再是真的，由于添加到Obj的属性，隐式解包的选项现在很少见-C声明）。

另一种解决方案：尝试Starscream - 一个原生的Swift Websocket库。
