How to load json file in cocos2d-x ios game using c++ project

I have a json file which contains my sprite animation details.How can I use in my cocos2d-x game using c++ in ios .I am using xcode.Can any one please please help me.I am really in a need of this.Please share the code if anyone has.

Here’s a basic example (disclaimer: not compiled, should be ok though):

void MyClass::loadJson(const char* json)
{  
  rapidjson::Document doc;
  doc.Parse<0>(json);

  if (!doc.HasParseError())
  {
     auto email = doc["email"].GetString();
  }
};

Remember to #include "json/document.h" either in your implementation or definition (header).
