iPhone TCPIP Socket 服务器客户端程序

使用iPhone TCP/IP Socket实现服务器/客户端通信

swift
import CocoaAsyncSocket
class Server: NSObject, GCDAsyncSocketDelegate {
    var socket: GCDAsyncSocket!
    
    override init() {
        super.init()
        
        socket = GCDAsyncSocket(delegate: self, delegateQueue: DispatchQueue.main)
    }
    
    func startServer() {
        do {
            try socket.accept(onPort: 8080)
        } catch {
            print("Failed to start server: \(error.localizedDescription)")
        }
    }
    
    func socket(_ sock: GCDAsyncSocket, didAcceptNewSocket newSocket: GCDAsyncSocket) {
        let address = newSocket.connectedHost ?? "unknown"
        let port = newSocket.connectedPort
        
        print("Accepted new client from \(address):\(port)")
        
        // 在这里处理客户端的请求和响应
    }
}

swift
import CocoaAsyncSocket
class Client: NSObject, GCDAsyncSocketDelegate {
    var socket: GCDAsyncSocket!
    
    override init() {
        super.init()
        
        socket = GCDAsyncSocket(delegate: self, delegateQueue: DispatchQueue.main)
    }
    
    func connectToServer() {
        do {
            try socket.connect(toHost: "127.0.0.1", onPort: 8080)
        } catch {
            print("Failed to connect to server: \(error.localizedDescription)")
        }
    }
    
    func socket(_ sock: GCDAsyncSocket, didConnectToHost host: String, port: UInt16) {
        print("Connected to server \(host):\(port)")
        
        // 在这里发送请求和接收响应
    }
}

swift
let data = "Hello, client!".data(using: .utf8)
newSocket.write(data, withTimeout: -1, tag: 0)

swift
sock.readData(withTimeout: -1, tag: 0)

swift
func socket(_ sock: GCDAsyncSocket, didRead data: Data, withTag tag: Int) {
    if let receivedData = String(data: data, encoding: .utf8) {
        print("Received data from client: \(receivedData)")
    }
}
