I tried to give a shadow to label text but it does not shown.
My code
private func drawValueLabel() {
valueLabel.layer.shadowColor = UIColor.red.cgColor
valueLabel.layer.shadowOffset = CGSize.init(width: 15.0, height: 15.0)
valueLabel.layer.shadowRadius = 3.0
valueLabel.layer.shadowOpacity = 1
valueLabel.layer.masksToBounds = false
valueLabel.clipsToBounds = false
valueLabel.layer.shouldRasterize = true
valueLabel.drawText(in: self.bounds)
}
Help me to show shadow
Thanks
I'm using this UIView extension for add shadow. With this extension you can add shadow from storyboard.
extension UIView {
@IBInspectable var shadow: Bool {
get {
return layer.shadowOpacity > 0.0
}
set {
if newValue == true {
self.addShadow()
}
}
}
func addShadow(shadowColor: CGColor = UIColor.black.cgColor,
shadowOffset: CGSize = CGSize(width: 1.0, height: 2.0),
shadowOpacity: Float = 0.4,
shadowRadius: CGFloat = 3.0) {
layer.shadowColor = shadowColor
layer.shadowOffset = shadowOffset
layer.shadowOpacity = shadowOpacity
layer.shadowRadius = shadowRadius
}
}
Your code is working fine for me. Try giving some smaller offset so that you would be able to see it like
label.layer.shadowOffset = CGSize.init(width: 3.0, height: 3.0)
使用此label.layer.shadowColor = UIColor.black.cgColor label.layer.shadowOpacity = 0.5 label.layer.shadowRadius = 2.0 label.layer.shadowOffset = CGSize(width: 2.0, height: 2.0)
