1.如果使用的是系统自带的
static Label* createWithSystemFont ( const std::string & text,
        const std::string & 	font,
        float 	fontSize,
        const Size & 	dimensions = Size::ZERO,
        TextHAlignment 	hAlignment = TextHAlignment::LEFT,
        TextVAlignment 	vAlignment = TextVAlignment::TOP 
)
auto labelscore = Label::createWithSystemFont(score, "Arial", 72);
2.如果是使用的是自己下载来的字体
static Label* createWithTTF ( const std::string & text,
  const std::string & 	fontFilePath,
  float 	fontSize,
  const Size & 	dimensions = Size::ZERO,
  TextHAlignment 	hAlignment = TextHAlignment::LEFT,
  TextVAlignment 	vAlignment = TextVAlignment::TOP 
) 
auto labelscore = Label::createWithTTF(score, "fonts/Marker Felt.ttf", 36);
