什么类子类 - NSView或NSButton [英] What class to subclass - NSView or NSButton

问题描述

我正在创建一个按钮，我应该继承NSView和NSButton吗？

I am creating a button and should I subclass NSView and or NSButton?

推荐答案

如果你只想做自定义绘图，请考虑子类化 NSButtonCell ，这是负责在按钮内绘制的类。如果这不够强大到能做你想要的，你应该继承NSButton，因为它将免费给你很多行为，并将允许你在Interface Builder中设置按钮，就像任何其他控件一样。

If you only want to do custom drawing, consider subclassing NSButtonCell, which is the class responsible for drawing within a button. If that's not powerful enough to do what you want, you should subclass NSButton, as it'll give you lots of behavior for free, and will let you set up the button in Interface Builder as you would any other control.
