问题描述

我怎样才能让我用swift画圈?

How can i make i circle picture with swift ?

我的视图控制器:

import UIKit
import Foundation

class FriendsViewController : UIViewController{

    @IBOutlet weak var profilPicture: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()
        profilPicture = UIImageView(frame: CGRectMake(0, 0, 100, 100))
    }
}

我的 profilPicture = UIImageView(frame: CGRectMake(0, 0, 100, 100)) 什么都不做..

My profilPicture = UIImageView(frame: CGRectMake(0, 0, 100, 100)) do nothing ..

推荐答案

import UIKit

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

  override func viewDidLoad() {
    super.viewDidLoad()

    image.layer.borderWidth = 1
    image.layer.masksToBounds = false
    image.layer.borderColor = UIColor.black.cgColor
    image.layer.cornerRadius = image.frame.height/2
    image.clipsToBounds = true
}

如果你想在扩展上使用它

If you want it on an extension

import UIKit

extension UIImageView {

    func makeRounded() {

        self.layer.borderWidth = 1
        self.layer.masksToBounds = false
        self.layer.borderColor = UIColor.black.cgColor
        self.layer.cornerRadius = self.frame.height / 2
        self.clipsToBounds = true
    }
}

这就是你所需要的......

That is all you need....
