本身UIText也是靠CCLabel来渲染的

 void Text::initRenderer()
{
 _labelRenderer = Label::create();
 addProtectedChild(_labelRenderer, LABEL_RENDERER_Z, -1);
}

CCLabel 有设置列间距行间距的方法

 // 行间距
 void setLineSpacing(float height);

 /**
  * Sets the additional kerning of the Label.
  *
  * @warning Not support system font.
  * @since v3.2.0
  *  列间距
  */
 void setAdditionalKerning(float space);

在 C++ 里添加行间距列间距方法然后暴露给lua

UIText中添加方法

// UIText.h 中

	//设置行间距
	void setLineSpacing(float height);
	//设置列间距
	void setAdditionalKerning(float dir);

// UIText.cpp 中

	//设置行间距
	void Text::setLineSpacing(float height)
	{
	    if (_labelRenderer == nullptr)
	        return;
	    
	    _labelRenderer->setLineSpacing(height);

	}
	//设置列间距
	void Text::setAdditionalKerning(float dir)
	{
	    if (_labelRenderer == nullptr)
	        return;
	        
	    _labelRenderer->setAdditionalKerning(dir);
	}

暴露给lua

策划像在CocosStudio中Text的高级属性配置用户数据

csd 内容

code

local exData = text:getComponent("ComExtensionData")
local data = exData:getCustomProperty();
-- data 就是 999999
