Java 如何在objective-c中实现客户端套接字

我也需要这样做：

import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.lang.ClassNotFoundException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class ClientSocketExample {
    public static void main(String[] args) {
        try {
            //
            // Create a connection to the server socket on the server application
            //
            InetAddress host = InetAddress.getLocalHost();
            Socket socket = new Socket(host.getHostName(), 7777);

            //
            // Send a message to the client application
            //
            ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());
            oos.writeObject("Hello There...");

            //
            // Read and display the response message sent by server application
            //
            ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
            String message = (String) ois.readObject();
            System.out.println("Message: " + message);

            ois.close();
            oos.close();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}

但在objective-c中，我看到有许多类使用socket，但我不知道如何在iphone项目中使用它，有人能帮我吗？谢谢

您可以异步上传，完整记录，然后在

或者像在unix和我使用的那样使用TCP套接字

请参阅此链接：您只能将ObjectInput/OutputStream用于另一个Java程序。我建议您使用XML、JSon或其他文本协议等可移植格式。

- (void)initNetworkCommunication {
    CFReadStreamRef readStream;
    CFWriteStreamRef writeStream;
    CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"localhost", 80, &readStream, &writeStream);
    inputStream = (NSInputStream *)readStream;
    outputStream = (NSOutputStream *)writeStream;
}
