以编程方式设置UIButton的buttonType [英] set UIButton's buttonType programmatically

问题描述

我在IB中添加了 UIButton ，但是此按钮后面的视图会改变颜色，我需要在 InfoDark <之间切换按钮的类型/ em>和 InfoLight 。但奇怪的是， buttonType 属性是只读的。那么如何在明暗信息按钮之间切换？

I have a UIButton which I've added in IB, however the view behind this button changes color and I need to switch the button's type between InfoDark and InfoLight. Bizarrely though, buttonType property is read only. So how can i switch between light and dark info buttons?

推荐答案

无法更改。 buttonType 一旦设置完毕。

There's no way to change the .buttonType once it's set.

您可以准备两个按钮，并根据背景颜色隐藏其中一个按钮。

You can prepare two buttons, and hide one of them depending on the background color.
