问题描述

如何使按钮的标题位于底部并以编程方式居中？

How can I make a button's title at bottom and centered programmatically?

推荐答案

子类 NSButtonCell 并覆盖 drawTitle：withFrame：inView： （ drawTitle（_，withFrame，inView ）迅速绘制），例如，通过操纵 frame 参数绘制居中的标题，或者自己绘制标题。然后将按钮的单元格类设置为子类。

Subclass NSButtonCell and override drawTitle:withFrame:inView:(drawTitle(_,withFrame,inView) in swift) to draw the title centered by manipulating frame parameter for example, or draw the title by yourself. Then set your button's cell class to your subclass.

或在按钮上放置 NSTextField ，设置约束以锚定

Or place NSTextField over your button, set constraints to anchor the bottomcenter of the button and set its text to whatever you want, and keep your buttons title empty.

不幸的是，没有 contentHorizo​​ntalAlignment c $ c>属性，就像在iOS中一样，因此您必须使用子类或其他UI组合来解决它。

Unfortunately, there is no contentHorizontalAlignment property, like in iOS, so you have to solve it with subclass or a different UI composing.
