扩大NSSlider级,向其推荐一个NSText 外地
原标题:Extend NSSlider class by appending a NSTextField to it

我想扩大NSSlider类别,使其有一个产出文本。 关于这一点,我想知道:

  1. my approach of wanting to append a textfield to NSSlider class is completely wrong and against MVC pattern;
  2. if it is not wrong how should I achieve this? Should I possibly extend NSSlider class with a Category?

事先感谢你

最佳回答

我要说的是,你的办法是完全错误的,但可能更容易形成一种观点(或也许是一种控制),即:contains既包括一个梯子,又是一个案文领域。

难道不像你想要改变先辈的表现方式——你只是想在先辈的旁边做一个文字,而实地的价值要与先辈的地位挂钩? 如果是,组成就是前进的道路。
