圆形UIButton [英] Round UIButton

问题描述

我想知道是否可以绘制圆形UIButton（不是圆角矩形）。

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。但是在点击按钮的那一刻，按钮的边界变得可见，因此它看起来像一个方形按钮，然后当点击结束时它再次看起来像一个圆形按钮。

我想按钮来即使在点击发生的那一刻，它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

您可能需要为此创建自定义控件，但是您真的需要一个圆形按钮吗？

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惯例，iPhone也不例外。用户希望按钮为圆角矩形。

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

更新以回复评论：

如果我说得对，你不是在寻找一个圆形按钮，而是一个可点击（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.

你可以使用 UIImageView 及其 touchesBegan 方法。

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，我以为你试图模仿真正的收音机。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.
