Here corner is working but shadow is not work in iOS 9 and 10 - ios

Question

Here corner is working but shadow is not work in iOS 9 and 10
and iOS 11 both are working fine
viewBlueMe.chatCellDesign([.topLeft,.bottomLeft,.topRight], [.layerMinXMinYCorner,.layerMinXMaxYCorner,.layerMaxXMinYCorner], radius: 5)
extenstion :
extension UIView {
func chatCellDesign(_ corners:UIRectCorner,_ cormerMask:CACornerMask, radius: CGFloat) {
if #available(iOS 11.0, *){
self.clipsToBounds = false
self.layer.cornerRadius = radius
self.layer.maskedCorners = cormerMask
self.layer.shadowColor = UIColor.gray.cgColor
self.layer.shadowOpacity = 1
self.layer.shadowOffset = CGSize.zero
self.layer.shadowRadius = 5
}else{
let rectShape = CAShapeLayer()
rectShape.bounds = self.frame
rectShape.position = self.center
rectShape.path = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius)).cgPath
self.layer.mask = rectShape
// FIXME: THIS CODE IS NOT WORK
self.layer.shadowColor = UIColor.gray.cgColor
self.layer.shadowOpacity = 1
self.layer.shadowOffset = CGSize.zero
self.layer.shadowRadius = 5
}
}
}
i need this type of output in iOS 9 and 10 also this is iOS11
Thanks in advance

Answer 1

Create one outerview and place your UILabel inside it, and please find below details,
outerView.layer.cornerRadius = 5.0
outerView.layer.shadowColor = UIColor.black.cgColor
outerView.layer.shadowOffset = CGSize.zero
outerView.layer.shadowOpacity = 0.2
outerView.layer.shadowRadius = 5.0
UPDATE
See below image,
and this is IBOutlets
#IBOutlet weak var tmpView: UIView!
#IBOutlet weak var innerView: UIView!
You can do this way,
innerView.roundCorners([.topLeft, .topRight, .bottomLeft], radius: 5)
tmpView.layer.shadowColor = UIColor.black.cgColor
tmpView.layer.shadowOffset = CGSize.zero
tmpView.layer.shadowOpacity = 0.2
tmpView.layer.shadowRadius = 10.0
Find UIView extension here,
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
}
}
this will give you below output,
FYI. Play around shadow property for exact output you want.
