ios - 如何让UIImage边缘更柔和？

Question

我有一个 UIImage，上面有一个 UIVisualEffectView。我想让边缘变得更柔和，以产生阴影效果。

我尝试使用 maskToBounds 但它没有什么区别。

let weekndImage = UIImage(named: "weeknd.jpg")
let weekndIV = UIImageView(image: weekndImage)
weekndIV.frame.size = CGSize(width: 200, height: 200)

let blur = UIBlurEffect(style: .light)
let blurView = UIVisualEffectView(effect: blur)


blurView.frame = weekndIV.bounds

weekndIV.addSubview(blurView)

weekndIV.layer.cornerRadius = 10
weekndIV.layer.masksToBounds = true

Answer 1

在设置blurView框架之后并将blurView添加到weekndIV View 之前移动这两行

weekndIV.layer.cornerRadius = 10
weekndIV.layer.masksToBounds = true
