推荐答案

为图像视图设置clipsToBounds = true

btnMyProfile.imageView.clipsToBounds = true

或使用

btnMyProfile.imageView.layer.masksToBounds = true

从苹果文档:

默认情况下，拐角半径不适用于 图层的内容属性；它仅适用于背景色和 图层的边框.但是，将masksToBounds属性设置为 true会将内容剪切到圆角.

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.
