How to add selected corner radius and shadow for UIView in swift

Can someone please help me with this question in iOS Swift. I have an UI view with drop shadow effect. I need corner radius for 3 corners except for one corner. Any help is appreciated.

Thanks, Dharani

Solution

  • You can use extension on UIView:

    Here is a sample I created on Playgrounds:

    let view = UIView()

extension UIView {
    func roundCorners(_ corners:UIRectCorner, radius: CGFloat) {
        let path = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))
        let mask = CAShapeLayer()
        mask.path = path.cgPath
        self.layer.mask = mask
    }
}
// customize where you want your roundCorners on your UIView
view.roundCorners([.topLeft, .topRight, .bottomRight], radius: 10)
