Question

我想使用UIView将不同的角半径值应用于iOS中swift的不同角落。这意味着topLeft, topRight, bottomLeft, bottomRight的{{1}}角应该具有不同 UIView（即1,5,10,15）。怎么实现呢？

我尝试以相同的方式应用cornerRadius，但它会覆盖之前的cornerRadius值。

Answer 1

如果您的部署目标是iOS 10以上，则应使用 maskedCorners

if #available(iOS 11.0, *) {
    customeView.clipsToBounds = true
    customeView.layer.cornerRadius = 5
    customeView.layer.maskedCorners = [.layerMaxXMaxYCorner, .layerMinXMaxYCorner, .layerMaxXMinYCorner, .layerMinXMinYCorner]
}

否则尝试

let path = UIBezierPath(roundedRect: customeView.bounds, byRoundingCorners:[.bottomLeft, .bottomRight], cornerRadii: CGSize(width: 5, height: 5))
            let mask = CAShapeLayer()
            mask.path = path.cgPath
            customeView.layer.mask = mask

Answer 2

尝试这个

let rectShape = CAShapeLayer()
    rectShape.bounds = self.myView.frame
    rectShape.position = self.myView.center
    rectShape.path = UIBezierPath(roundedRect: self.myView.bounds, byRoundingCorners: [.bottomLeft , .bottomRight , .topLeft], cornerRadii: CGSize(width: 20, height: 20)).cgPath
    self.myView.layer.backgroundColor = UIColor.green.cgColor
    self.myView.layer.mask = rectShape

如何在iOS Swift中将不同的角半径应用到UIView的不同角落？
