如何将图像塑造成圆形
How to shape an Image into an circle
我正在取消 UiKit 图像选择器并尝试为用户设置个人资料图片。一切正常,图像得到显示。但我想把它变成一个圆圈。我尝试使用带圆圈的 clipShape,但它不起作用。我遵循了教程“我的图像 1:SwiftUI 中的照片选择器和相机”

你快到了:)
你唯一的错误是你放置修饰符的顺序。订单很重要!!
将 scaledToFill()
和 clipShape()
放在框架修饰符之前。
像这样:
.resizable()
.scaledToFill()
.clipShape(Circle())
.frame(width: size, height: size)
