JS 部分的代码：shareWX：function（）

{

auto size = Director::getInstance()->getWinSize();

auto pScreen = RenderTexture::create(size.width,size.height);
auto pCurScene = Director::getInstance()->getRunningScene();
pScreen->begin();
pCurScene->visit();
pScreen->end();
pScreen -> saveToFile(StringUtils::format("screen_capture.png"),Image::Format::PNG);
pScreen->cleanup();
JniMethodInfo Fanrncho_minfo;
bool isHave = JniHelper::getStaticMethodInfo(Fanrncho_minfo,"com/maple/madherogo/WechatHelper","share","(Ljava/lang/String)V");

}

native 端的代码OC or C++
