WebSocket 客戶端庫：SwiftWebSocket

SwiftWebSocket 是高性能的 WebSocket 客戶端庫。

特性：

• Pure Swift solution. No need for Objective-C Bridging.

• Reads compressed messages (permessage-deflate). IETF Draft

• Strict UTF-8 processing.

• The API is modeled after the Javascript API.

• TLS / WSS support.

• binaryTypeproperty to choose between[UInt8]orNSDatamessages.

• Zero asserts. All networking, stream, and protocol errors are routed through theerrorevent.

• Send pings and receive pong events.

• High performance.

例子：

func echoTest(){
    var messageNum = 1
    var ws = WebSocket(url: "wss://echo.websocket.org")
    var send : ()->() = {
        var msg = "#\(messageNum++): \(NSDate().description)"
        println("send: \(msg)")
        ws.send(msg)
    }
    ws.event.open = {
        println("opened")
        send()
    }
    ws.event.close = { (code, reason, clean) in
        println("close")
    }
    ws.event.error = { (error) in
        println("error \(error.localizedDescription)")
    }
    ws.event.message = { (message) in
        if let text = message as? String {
            println("recv: \(text)")
            send()
        }
    }
}
