  最近使用Unity3d制作的IOS游戏需要加入联网对战功功能,因此使用ObjC语言利用IOS SDK的GameKit.framework的Peer-to-peer Connectivity实现了网络连接,在此分享。

啥话都不说,先上代码。点我下载工程文件

类NetWorkP2P,继承自NSObject。提供GKSessionDelegate和GKPeerPickerControllerDelegate的实现。并且利用单例模式实现一个类方法+( NetWorkP2P *) sharedNetWorkP2P;此方法返回一个NetWorkP2P的实例。

fileName:NetWorkP2PBinding.m在此文件中实现C语言接口,以方便在UnityScript中调用。

//NetWorkP2PBinding.mm
#import "NetWorkP2P.h"

extern "C"{
void _showPeerPicker()
{
[[NetWorkP2P sharedNetWorkP2P] showPeerPickerController];
NSLog(
@"call the mothed _showPeerPicker");
}

const char* _getName()
{
return [@"fyn" UTF8String];
}
int _getOpponentScore()
{
return [[NetWorkP2P sharedNetWorkP2P]getOpponentScore];
}
int _getPlayerScore()
{
return [[NetWorkP2P sharedNetWorkP2P]getPlayerScore];
}

void _addTheScore( UInt32 score)
{
[[NetWorkP2P sharedNetWorkP2P] addTheScore:score];
}
void _addTheTimes()
{
[[NetWorkP2P sharedNetWorkP2P] addTimes];
}
int _getOpponentTimes()
{
return [[NetWorkP2P sharedNetWorkP2P] getOpponentTimes];
}
int _getPlayerTimes()
{
return [[NetWorkP2P sharedNetWorkP2P] getPlayerTimes];
}
const char * _getOpponentID()
{
return [[[NetWorkP2P sharedNetWorkP2P ]getOpponentID] UTF8String];
}
}

FileName:P2PBinding.cs 这是在Unity3d中C#脚本,在这里面调用NetWorkP2PBinding.mm实现的C语言方法。

//P2PBinding.cs

using UnityEngine;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Runtime.InteropServices;


public class P2PBinding{
[DllImport(
"__Internal")]
private static extern void _showPeerPicker();

public static void showPeerPicker()
{
if(Application.platform==RuntimePlatform.IPhonePlayer)
_showPeerPicker();
}

[DllImport(
"__Internal")]
private static extern int _getOpponentScore();

[DllImport(
"__Internal")]
private static extern int _getOpponentTimes();

[DllImport(
"__Internal")]
private static extern int _getPlayerScore();

[DllImport(
"__Internal")]
private static extern int _getPlayerTimes();

[DllImport(
"__Internal")]
private static extern void _addTheTimes();

[DllImport(

private static extern void _addTheScore(int score);

public static int getOpponentScore()
{
if(Application.platform==RuntimePlatform.IPhonePlayer)
{
return _getOpponentScore();
}
return -1;
}
public static int getOpponentTimes()
{
if(Application.platform==RuntimePlatform.IPhonePlayer)
{
return _getOpponentTimes();
}
return -1;
}
public static int getPlayerScore()
{
if(Application.platform==RuntimePlatform.IPhonePlayer)
{
return _getPlayerScore();
}
return -1;
}
public static int getPlayerTimes()
{
if(Application.platform==RuntimePlatform.IPhonePlayer)
{
return _getPlayerTimes();
}
return -1;
}
public static void addTheScore(int score)
{
if(Application.platform==RuntimePlatform.IPhonePlayer)
{
_addTheScore(score);
}
}
public static void addTheTimes()
{
_addTheTimes();
}
}

FileName:GameDate.cs 此文件提供游戏的数据,并保持和NetWorkP2P文件中数据同步,将此文件附加到一个GameObject上。

using UnityEngine;
using System.Collections;

public class GameDate : MonoBehaviour {

public string opponentID;

public int playerTimes;
public int opponentTimes;
public int playerScore;
public int opponentScore;

// Use this for initialization
void Start () {
P2PBinding.showPeerPicker();
}

// Update is called once per frame
void Update () {
opponentTimes
=P2PBinding.getOpponentTimes();
opponentScore
=P2PBinding.getOpponentScore();
}
}
