我正在调用一个设置 UIImageView 的函数:
func setupImageView(_ imageView: UIImageView) {}
我想给那个 UIImageView 一个图像,把它的角弄圆,并给它两个不同的边框。
这是我目前正在做的事情:
imageView.image = imageConstants.imageThatIsWanted
imageView.clipsToBounds = true
imageView.layer.cornerRadius = imageView.frame.height / 2
imageView.layer.borderWidth = 3.0
imageView.layer.borderColor = UIColor.white.cgColor
在白色边框周围应用第二个蓝色边框颜色的最佳方法是什么?
我尝试创建一个子图层作为 CALayer 并给它一个蓝色边框,但这在图像后面,也在白色边框内。我还尝试绘制 UIBezierPath,但它也位于白色边框内。

import UIKit
class ViewController: UIViewController {
@IBOutlet weak var secondView: UIView!
@IBOutlet weak var imgView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
imgView.layer.cornerRadius = imgView.frame.size.height/2
secondView.layer.cornerRadius = secondView.frame.size.height/2
imgView.layer.borderWidth = 5.0
imgView.layer.borderColor = UIColor.red.cgColor
imgView.clipsToBounds = true
secondView.clipsToBounds = true
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
