如何使用ShareSDK实现Cocos2d-x的Android/iOS分享与授权

1. Cocos2DX 简介

Cocos2d-x是一套成熟的开源跨平台游戏开发框架。其引擎提供了图形渲染、GUI、音频、网络、物理、用户输入等丰富的功能，被广泛应用于游戏开发及交互式应用的构建。引擎的核心采用C++ 编写，支持使用C++、Lua或者JavaScript进行开发。同时Cocos2d-x可以适配IOS、Android、HTML5、Windows和Mac系统。

Cocos2d-x在中国及全球都有一定的市场份额，为了给开发出来的游戏增加知名度，更好的进行营销，社交分享功能是必不可少的。但是所要分享的平台针对全球不同的区域有不同的侧重点，这就需要短时间内接入多个社交平台，但是每个平台的接入时间成本按天计算，多个平台叠加在一起的时间就很不乐观。所以使用Cocos2d-x引擎的开发人员急需一种能够让开发者快速接入授权、分享功能的SDK。

2. Cocos2d-x集成ShareSDK过程如下：

官方插件地址：

Android 集成

首先下载官方插件，下载完毕之后需要做如下几步工作

• 把ShareSDK的cocos2dx的proj.android-studio项目里的libs包复制到你的项目里，除了armeabi目录不用复制其他都要。

• 把ShareSDK的cocos2dx的New-C2DX-For-ShareSDK项目里的Classes目录下的文件都复制到你的项目里的Classes目录下。

• 在jni/Android.mk添加下面代码来引入相关文件，如：

../../Classes/AppDelegate.cpp \
../../Classes/HelloWorldScene.cpp \
../../Classes/C2DXShareSDK/Android/ShareSDKUtils.cpp \
../../Classes/C2DXShareSDK/C2DXShareSDK.cpp \
../../Classes/C2DXShareSDK/Android/JSON/CCJSONConverter.cpp \
../../Classes/C2DXShareSDK/Android/JSON/cJSON/cJSON.cLOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes \

$(LOCAL\_PATH)/../../Classes/C2DXShareSDK \\$(LOCAL_PATH)/../../Classes/C2DXShareSDK/Android \
$(LOCAL\_PATH)/../../Classes/C2DXShareSDK/Android/JSON \\$(LOCAL_PATH)/../../Classes/C2DXShareSDK/Android/JSON/cJSON

• 在proj.android-studio工程下，app目录下，build.gradle文件内，寻找到dependencies标签，配置如下的代码

compile project(':libcocos2dx')

• 在主activity里(一般在cocos项目的此目录下面：\proj.android-studio\src\org\cocos2dx\cpp\AppActivity.java)的onCreate方法里添加ShareSDKUtils.prepare()方法。

protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState); ShareSDKUtils.prepare();
}

• 各个平台的配置方式：平台的配置在libcocos2dx这个依赖工程内，工程根目录下边有一个MobSDK.gradle文件，写法示例如下边的代码所示，用户需要用自己申请到的Key来替换下文中的key。平台的选择也根据自己的需要来进行增加删除。

apply plugin: 'com.mob.sdk'MobSDK {
appKey "moba6b6c6d6"
appSecret "b89d2427a3bc7ad1aea1e1e8c1d36bf3"

ShareSDK {

}
}}

iOS 集成

• 将下面红色方框的资源文件拖到Cocos2d-x项目中

• 将SDK文件夹拖进项目（下载地址）

注意：请务必在上述步骤中选择“Create groups for any added folders”单选按钮组。如果你选择“Create folder references for any added folders”，一个蓝色的文件夹引用将被添加到项目并且将无法找到它的资源。

• 添加必须的依赖库

libc++.tbd

libz.tbd

libsqlite3.tbd

各社交平台所需依赖库：

新浪微博：

ImageIO.framework

Photos.framework

Instagram：

AssetsLibrary.framework

Photos.framework

美拍：

AssetsLibrary.framework

添加依赖库的方法如下

配置UrlScheme和白名单等，各个社交平台需要的配置可以参考快速集成文档中的URL Scheme和白名单配置项。

在项目工程的Info.plist 中如图增加 MOBAppKey 和 MOBAppSecret 两个字段

在 MOBAppKey中 设置ShareSDK的appKey，如果尚未在ShareSDK官网注册过App，请移步到 登录后台 进行应用注册也可以点击 链接 看里面的操作步骤。

3. 代码实现

• 初始化： 打开Classes目录下边的AppDelegate.cpp文件，直接拷贝粘贴代码进行初始化工作。

导入头文件

# include "C2DXShareSDK.h"

初始化

bool AppDelegate::applicationDidFinishLaunching()
{ //初始化ShareSDK
this->initShareSDKConfig();
}

void AppDelegate::initShareSDKConfig()
{ //设置平台配置
//Platforms
__Dictionary *totalDict = __Dictionary::create();
//新浪微博
__Dictionary *sinaWeiboConf= __Dictionary::create();
sinaWeiboConf->setObject(__String::create("568898243"), "app_key");
sinaWeiboConf->setObject(__String::create("38a4f8204cc784f81f9f0daaf31e0 2e3"), "app_secret");
sinaWeiboConf->setObject(__String::create("www.sharesdk.cn"), "re direct_uri");
stringstream sina;
sina << cn::sharesdk::C2DXPlatTypeSinaWeibo;
totalDict->setObject(sinaWeiboConf, sina.str());
//微信
__Dictionary *wechatConf = __Dictionary::create();
wechatConf->setObject(__String::create("wx4868b35061f87885"), "app_id");
wechatConf->setObject(__String::create("64020361b8ec4c99936c0e3999a9f249 "), "app_secret");
stringstream wechat;
wechat << cn::sharesdk::C2DXPlatTypeWechatPlatform;
totalDict->setObject(wechatConf, wechat.str());
//QQ
__Dictionary *qqConf = __Dictionary::create();
qqConf->setObject(__String::create("100371282"), "app_id");
qqConf->setObject(__String::create("aed9b0303e3ed1e27bae87c33761161d"), "app_key");
stringstream qq;
qq << cn::sharesdk::C2DXPlatTypeQQPlatform;
totalDict->setObject(qqConf, qq.str());
//Facebook
__Dictionary *fbConf = __Dictionary::create();
fbConf->setObject(__String::create("107704292745179"), "api_key");
fbConf->setObject(__String::create("38053202e1a5fe26c80c753071f0b573"), "app_secret");
stringstream facebook;
facebook << cn::sharesdk::C2DXPlatTypeFacebook;
totalDict->setObject(fbConf, facebook.str());
//Twitter
__Dictionary *twConf = __Dictionary::create();
twConf->setObject(__String::create("LRBM0H75rWrU9gNHvlEAA2aOy"), "consumer_key");
twConf->setObject(__String::create("gbeWsZvA9ELJSdoBzJ5oLKX0TU09UOwrzdGfo9Tg7DjyGuMe8G"), "consumer_secret");
twConf->setObject(__String::create("www.mob.com"), "redirect_uri" ) ;
stringstream twitter;
twitter << cn::sharesdk::C2DXPlatTypeTwitter;
totalDict->setObject(twConf, twitter.str());

cn::sharesdk::C2DXShareSDK::registerAppAndSetPlatformConfig("moba6b6c6d6","b89d2427a3bc7ad1aea1e1e8c1d36bf3",totalDict);
}

以上平台的app_key、app_secret等字段不同分享平台可能不同，详情可参考：《统一表》。

• 授权功能：

C2DXShareSDK::authorize(C2DXPlatTypeSinaWeibo, authResultHandler);

authResultHandler是默认定制的一个回调类，也可以自己写一个新的回调类来替代此类

//授权回调void authResultHandler(int seqId, cn::sharesdk::C2DXResponseState state, cn::sharesdk::C2DXPlatType platType, __Dictionary *result){ switch (state)
{ case cn::sharesdk::C2DXResponseStateSuccess:
{ log("Success");
//输出信息
try
{
__Array *allKeys = result -> allKeys();
allKeys->retain(); for (int i = 0; i < allKeys -> count(); i++)
{
__String *key = (__String *)allKeys -> getObjectAtIndex(i);
Ref *obj = result -> objectForKey(key -> getCString());
log("key = %s", key -> getCString()); if (dynamic_cast<__String *>(obj))
{ log("value = %s", dynamic_cast<__String *>(obj) -> getCString());
} else if (dynamic_cast<__Integer *>(obj))
{ log("value = %d", dynamic_cast<__Integer *>(obj) -> getValue());
} else if (dynamic_cast<__Double *>(obj))
{ log("value = %f", dynamic_cast<__Double *>(obj) -> getValue());
}
}
allKeys->release();
} catch(...)
{ log("==============error");
}
} break; case cn::sharesdk::C2DXResponseStateFail:
{ log("Fail"); //回调错误信息
__Array *allKeys = result->allKeys();
allKeys->retain(); for (int i = 0; i < allKeys-> count(); i++)
{
__String *key = (__String*)allKeys->getObjectAtIndex(i);
Ref *obj = result->objectForKey(key->getCString());
log("key = %s", key -> getCString()); if (dynamic_cast<__String *>(obj))
{ log("value = %s", dynamic_cast<__String *>(obj) -> getCString());
} else if (dynamic_cast<__Integer *>(obj))
{ log("value = %d", dynamic_cast<__Integer *>(obj) -> getValue());
} else if (dynamic_cast<__Double *>(obj))
{ log("value = %f", dynamic_cast<__Double *>(obj) -> getValue());
}
}
} break; case cn::sharesdk::C2DXResponseStateCancel:
{ log("Cancel");
} break; default: break;
}
}

• 获取用户的信息

授权之后，可以通过如下的方法来获取用户信息。

C2DXShareSDKC ::getUserInfo(C2DXPlatTypeSinaWeibo, getUserResultHandler);

• 分享

在需要分享操作的代码块中进行构造分享参数，示例如下：

__Dictionary *content = __Dictionary::create();
content -> setObject(__String::create("分享文本"), "text"); // 分享文本
content -> setObject(__String::create("HelloWorld.png"), "image");// 分享图片
content -> setObject(__String::create("测试标题"), "title"); // 分享标题
content -> setObject(__String::create("www.mob.com"), "url"); // 分享url
content -> setObject(__String::createWithFormat("%d", cn::sharesdk::C2DXContentTypeWebPage), "type"); /

构造分享内容字段参数值请参考：《分享内容字段值表》

调用分享方法：

//弹出菜单C2DXShareSDK::showShareMenu(NULL,content,100,100, shareContentResultHandler);// 第3，4个参数传入 iPad 视图要显示的坐标点，详见API说明//无UI，直接分享C2DXShareSDK::shareContent(cn::sharesdk::C2DXPlatTypeSinaWeibo, content, shareContentResultHandler);
//弹出编辑界面分享C2DXShareSDK::showShareView(cn::sharesdk::C2DXPlatTypeSinaWeibo, content, shareContentResultHandler);

设置分享回调方法 shareContentResultHandler，示例如下：

//分享回调void shareContentResultHandler(int seqId, cn::sharesdk::C2DXResponseState state, cn::sharesdk::C2DXPlatType platType, __Dictionary *result){ switch (state)
{ case cn::sharesdk::C2DXResponseStateSuccess:
{ log("Success");
} break; case cn::sharesdk::C2DXResponseStateFail:
{ log("Fail"); //回调错误信息
__Array *allKeys = result->allKeys();
allKeys->retain(); for (int i = 0; i < allKeys-> count(); i++)
{
__String *key = (__String*)allKeys->getObjectAtIndex(i);
Ref *obj = result->objectForKey(key->getCString());
log("key = %s", key -> getCString()); if (dynamic_cast<__String *>(obj))
{ log("value = %s", dynamic_cast<__String *>(obj) -> getCString());
} else if (dynamic_cast<__Integer *>(obj))
{ log("value = %d", dynamic_cast<__Integer *>(obj) -> getValue());
} else if (dynamic_cast<__Double *>(obj))
{ log("value = %f", dynamic_cast<__Double *>(obj) -> getValue());
}
}
} break; case cn::sharesdk::C2DXResponseStateCancel:
{ log("Cancel");
} break; default: break;
}
}
