Question

I would like to add a shadow effect to my UITextField currently what I\'m achieving is this:
As you can see the shadow is not rounded in the corners. My code:

Answer 1

extension UITextField {

    func addShadowToTextField(color: UIColor = UIColor.gray, cornerRadius: CGFloat) {

    self.backgroundColor = UIColor.white
    self.layer.masksToBounds = false
    self.layer.shadowColor = color.cgColor
    self.layer.shadowOffset = CGSize(width: 0, height: 0)
    self.layer.shadowOpacity = 1.0
    self.backgroundColor = .white
    self.layer.cornerRadius = cornerRadius
   }
}

Add Extension and Usage:

    dateTxtFld.addShadowToTextField(cornerRadius: 3)
    dateTxtFld.addShadowToTextField(color: UIColor.blackColor, cornerRadius: 3)
