问题描述

我想知道是否可以绘制圆形 UIButton(不是圆形矩形).

I want to know whether drawing a round UIButton(not rounded rect) is possible.

当我在自定义类型的 UIButton 中添加圆形图像时，它看起来像一个圆形按钮.但是在单击按钮的那一刻，按钮的边界变得可见，因此它看起来像一个方形按钮，然后在单击结束时再次看起来像一个圆形按钮.
即使在点击发生的那一刻，我也希望按钮看起来像一个圆形按钮.这可能吗?

When I add a round image in a UIButton of type custom, then it looks like a round button. But at the moment the button is clicked the boundary of the button becomes visible, so that it looks like a square button, then again when the click ends it looks like a round button.
I want the button to look like a round button even at the moment the click happens. is this possible?

推荐答案

您可能必须为此创建一个自定义控件，但您真的需要圆形按钮吗?

You'd probably have to create a custom control for that, but do you really need a round button?

每个平台都有其 UI 约定，iPhone 也不例外.用户希望按钮是圆角矩形.

Every platform has its UI conventions, and the iPhone is no exception. Users expect the buttons to be rounded rectangles.

更新回应评论:

如果我没看错，那么您不是在寻找圆形按钮，而是在寻找可点击(可触摸)的图像.

If I'm getting this right, you're not looking for a round button, but rather a clickable (touchable) image.

您可以使用 UIImageView 及其 touchesBegan 方法.

You can use an UIImageView and its touchesBegan method.

更新 2:

等一下.我们在谈论什么样的单选按钮?出于某种原因，我以为你是在模仿真正的收音机.如果您正在谈论 单选按钮 组，请使用 UISegmentedControl 或 UIPicker.

Wait a second. What kind of radio button are we talking about? For some reason I thought you were trying to imitate a real radio. If you're talking about a radio button group, please use a UISegmentedControl or a UIPicker.
