问题
My Unity project related with socket communication works fine on my Mac. I run a C# server on my own computer's terminal and then run the unity project. The unity project can connect to my server and receive the message sent by the server. Every thing works fine. However, when I Build and Run this unity project to my iPhone, it comes with some problems:

Because it works well on the computer, so I think the IP address is not the problem. Can anyone help? Here is the code for my server.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Sockets;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
TcpListener serverSocket = new TcpListener(8888);
TcpClient clientSocket = default(TcpClient);
serverSocket.Start();
Console.WriteLine(" >> Server Started");
clientSocket = serverSocket.AcceptTcpClient();
Console.WriteLine(" >> Accept connection from client");
// Console.ReadLine();
while (true) {
String textinput;
textinput = Console.ReadLine ();
NetworkStream serverStream = clientSocket.GetStream ();
byte[] outStream = System.Text.Encoding.ASCII.GetBytes (textinput + "$");
serverStream.Write (outStream, 0, outStream.Length);
serverStream.Flush ();
}
clientSocket.Close();
serverSocket.Stop();
Console.WriteLine(" >> exit");
Console.ReadLine();
}
}
}
And here is the code for my unity project:
using UnityEngine;
using System.Collections;
using System;
using System.Net.Sockets;
using System.Text;
using System.Threading;
using UnityEngine.UI;
public class Client : MonoBehaviour {
System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();
private Thread oThread;
// for UI update
public GameObject updatetext;
String tempMesg = "Waiting...";
// Use this for initialization
void Start () {
updatetext.GetComponent<Text>().text = "Waiting...";
clientSocket.Connect("10.132.198.29", 8888);
oThread = new Thread (new ThreadStart (getInformation));
oThread.Start ();
Debug.Log ("Running the client");
}
void getInformation(){
while (true) {
try {
NetworkStream networkStream = clientSocket.GetStream ();
byte[] bytesFrom = new byte[10025];
networkStream.Read (bytesFrom, 0, (int)bytesFrom.Length);
string dataFromClient = System.Text.Encoding.ASCII.GetString (bytesFrom);
dataFromClient = dataFromClient.Substring (0, dataFromClient.IndexOf ("$"));
Debug.Log (" >> Data from Server - " + dataFromClient);
tempMesg = dataFromClient;
string serverResponse = "Last Message from Server" + dataFromClient;
Byte[] sendBytes = Encoding.ASCII.GetBytes (serverResponse);
networkStream.Write (sendBytes, 0, sendBytes.Length);
networkStream.Flush ();
Debug.Log (" >> " + serverResponse);
} catch (Exception ex) {
Debug.Log ("Exception error:" + ex.ToString ());
oThread.Abort ();
oThread.Join ();
}
}
}
}
And I am wondering do I need to set something for enabling the socket plugin in Xcode?
