如何在 Swift 中正确设置 imageView，如 imageContacts? [英] How to set imageView in circle like imageContacts in Swift correctly?

问题描述

我想像图片联系人一样在 imageView 中显示一张图片(在一个圆圈中)但是当我尝试显示这个时，imageView 会重新调整他的大小并且这个在一个圆圈中不能正确显示.

I want to show a picture into imageView like the image contact (in a circle) But when I try to show this, the imageView rescale his size and this doesn't show correctly in a circle.

 image.layer.borderWidth=1.0
 image.layer.masksToBounds = false
 image.layer.borderColor = UIColor.whiteColor().CGColor
 image.layer.cornerRadius = image.frame.size.height/2
 image.clipsToBounds = true

我想这样显示:

但我明白了:

如何将图像调整为 UIImageView 大小以显示为圆形?

How can do the image resize to UIImageView size to show as a circle?

谢谢！

推荐答案

image 使用的 frame 尺寸是多少?如果我将框架设置为正方形，我可以得到一个完美的圆形.

What frame size are you using for image? I can get a perfect circle if I set the frame to be a square.

let image = UIImageView(frame: CGRectMake(0, 0, 100, 100))
