如何更改图像的大小？图像无法填充 [英] How to change image's size? Image does not fill

问题描述

我正在尝试使图像四舍五入。它已经是128x128（宽度和高度），角半径是64.我想在剪切照片之前放大以拍摄照片的完整圆角尺寸。

如何缩放？

我的代码：

  profileImage.layer.cornerRadius = 64 
 profileImage.clipsToBounds = true

UIImageView 的内容模式设置为 .scaleAspectFill 。这样，图像将填满整个容器而不会扭曲它。

  profileImage.contentMode = .scaleAspectFill

profileImage.layer.cornerRadius = 64
profileImage.clipsToBounds = true

I want to make it like this:
