cocos2dx-IOS微信分享

一、进入微信开放平台点击打开链接

• 点击进入“开放平台”
  
  

• 点击进入“资源中心”
  
  

• 点击“移动应用”
  
  

• 点击“iOS接入指南”后，点击文档最下方微信SDK Sample Demo源码

二、把下载好的demo找到图中文件，放到一个文件夹SDK1.6.2中

C2DShareInstance.h C2DShareInstance.mm(.mm是用于C++与IOS混编)是用于cocos2dx 与 iOS 进行交互的，内部实现如下：

1. //C2DShareInstance.h
   #ifndef C2DShareInstance_h
   #define C2DShareInstance_h
   
   #include "cocos2d.h"
   
   class C2DXShareInstance
   {
   protected:
       C2DXShareInstance(){}   //构造函数是私有的
       static C2DXShareInstance *m_pInstance;
       
   public:
       static C2DXShareInstance *GetInstance();
       //直接分享
       void shareContentClickHandler(std::string strLinkURL, std::string strLinkTagName, std::string strLinkTitle, std::string strLinkDescription, std::string strImage, int wxType);
   };

   
   
2. CD2ShareInstance.cpp实现
   

   //
   //  C2DShareInstance.m
   //  MyGame
   //
   //  Created by apple on 16/1/22.
   //
   //
   
   #import 
   //#import "AppController.h"
   #include "C2DShareInstance.h"
   
   //winxin
   #import "WXApiManager.h"
   #import "WXApiRequestHandler.h"
   #import "RespForWeChatViewController.h"
   #import "Constant.h"
   
   C2DXShareInstance *C2DXShareInstance::m_pInstance = NULL;
   
   C2DXShareInstance* C2DXShareInstance::GetInstance()
   {
       if(m_pInstance == NULL)  //判断是否第一次调用
       {
           //向微信注册
           [WXApi registerApp:@"wx0d5597c5317a4696"];
           m_pInstance = new C2DXShareInstance();
       }
       return m_pInstance;
   }
   
   void C2DXShareInstance::shareContentClickHandler(std::string strLinkURL, std::string strLinkTagName, std::string strLinkTitle, std::string strLinkDescription, std::string strImage, int wxType)
   {
       NSString *nsLinkURL = [[NSString alloc] initWithCString:strLinkURL.c_str()];
       NSString *nsLinkTagName = [[NSString alloc] initWithCString:strLinkTagName.c_str()];

       NSString *nsImage= [[NSString alloc] initWithCString:strImage.c_str()];
       
       UIImage *thumbImage = [UIImage imageNamed:nsImage];
       [WXApiRequestHandler sendLinkURL:nsLinkURL
                                TagName:nsLinkTagName
                                  Title:nsLinkTitle
                            Description:nsLinkDescription
                             ThumbImage:thumbImage

   其中使用单例模式在调用的C2DXShareInstance* C2DXShareInstance::GetInstance()时候，向微信注册，这个"wx0d5597c5317a4696"是要填写自己AppID。AppID获得，是在管理中心申请的，通过后会告诉你。（这个应该是与该App相关联，如果应用没有注册，那么分享不会成功。）
   
   
3. SDK1.6.2加入你要实现分享的工程当中。
   
   
4. 添加CoreTelephony.framework libWeChatSDK.a libSqlite3.0tbd libz.tbd库文件，让其能链接编辑。如果不明白怎么添加，可以看看官方文档，写的很详细。
   
   
5. 最后在要分享的地方添加代码
   

   #if(CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
        std::string strLinkURL = "http://www.baidu.com";
        std::string strLinkTitle = CUtilEx::getString("app_name");
        std::string strLinkDescription = CUtilEx::getString("room_shared");
        std::string strImage = "Icon-40.png";
        C2DXShareInstance::GetInstance()->shareContentClickHandler(strLinkURL, "", strLinkTitle, "", strImage,1);
   #endif

   
   

三、注意事项：

1. demo是纯IOS，我们使用的时候，要把它剥离出来
2. 这里只实现了微信分享。微信支付，微信登陆等等没有实现，需要时自行添加。
3. 关键地方AppID要时自己应用在微信开放平台申请的AppID。
