Closed 4 years ago.
UIView Custom Class trigger only shadow. I want to display both shadow and rounded corner for specific edges.Here is my code. Any suggestions would be appreciated.
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
}
}
class CustomView: UIView {
override func layoutSubviews() {
self.shadowColor = UIColor.darkGray
self.shadowOffset = CGSize(width: 4, height: 4)
self.shadowOpacity = 0.5
self.shadowRadius = 6.0
//only rounded corners triggered in UI
self.backgroundColor = UIColor.white
self.roundCorners(corners: [.topRight, .bottomRight], radius: 15.0)
}
}
Thanks in advance

Answer 1

Use separate views for the shadow and the border. The base view is transparent and has the shadow. The border view clips any other subcontent that it has to its borders. See the code below.
// add the shadow to the base view
baseView.backgroundColor = UIColor.clear
baseView.layer.shadowColor = UIColor.black.cgColor
baseView.layer.shadowOffset = CGSize(width: 3, height: 3)
baseView.layer.shadowOpacity = 0.7
baseView.layer.shadowRadius = 4.0
// add the border to subview
let borderView = UIView()
borderView.frame = baseView.bounds
borderView.layer.cornerRadius = 10
borderView.layer.borderColor = UIColor.black.cgColor
borderView.layer.borderWidth = 1.0
borderView.layer.masksToBounds = true
baseView.addSubview(borderView)
// add any other subcontent that you want clipped
let otherSubContent = UIImageView()
otherSubContent.image = UIImage(named: "lion")
otherSubContent.frame = borderView.bounds
borderView.addSubview(otherSubContent)

Use this function:-
func addShadow(view: UIView, corner: CGFloat) {
view.layer.shadowColor = UIColor.gray.cgColor
view.layer.shadowOpacity = 0.5
view.layer.shadowRadius = 2
view.layer.shadowOffset = CGSize(width: 1, height: 1)
view.layer.masksToBounds = false
view.layer.cornerRadius = corner
}
