如何在swift 4中使图像视图圆形 [英] How to make image view round in swift 4

问题描述

虽然互联网上有这个问题的解决方案，但我无法这样做，我想对图像进行四舍五入.

Though there is solution of this question is present in internet, but I am unable to do so, I want to round a image.

我正在使用的代码:

extension UIImageView {        
    func makeRounded() {
        let radius = self.frame.width/2.0
        self.layer.cornerRadius = radius
        self.layer.masksToBounds = true
    }
 }

然后我在 viewdidload() 中调用这个函数，就像 imgvw.makeRounded().但它不会到来.请帮忙

then i call this function in viewdidload() like imgvw.makeRounded(). but it is not coming. please help

上一个链接对我没有帮助

推荐答案

import UIKit

class ViewController: UIViewController {
  @IBOutlet weak var image: UIImageView!

  func makeRounded() {

    image.layer.borderWidth = 1
    image.layer.masksToBounds = false
    image.layer.borderColor = UIColor.blackColor().CGColor
    image.layer.cornerRadius = image.frame.height/2 //This will change with corners of image and height/2 will make this circle shape
    image.clipsToBounds = true
}
