推荐答案

为你的 imageview 设置 clipsToBounds = true

set clipsToBounds = true for your imageview

btnMyProfile.imageView.clipsToBounds = true

或使用

btnMyProfile.imageView.layer.masksToBounds = true

来自苹果文档:

默认情况下，圆角半径不适用于图层的内容属性；它仅适用于背景颜色和层的边界.但是，将 maskToBounds 属性设置为true 导致内容被剪裁到圆角.

By default, the corner radius does not apply to the image in the layer’s contents property; it applies only to the background color and border of the layer. However, setting the masksToBounds property to true causes the content to be clipped to the rounded corners.

其他选项使用 UIBezierPath
