I have written the following code and don't know what I'm doing wrong the button is not reflecting the gradient
I also tried calling my function under awakefromNib
class ButtonGradient: UIButton {
var color1 = #colorLiteral(red: 0.3411764801, green: 0.6235294342, blue: 0.1686274558, alpha: 1)
var color2 = #colorLiteral(red: 0.521568656, green: 0.1098039225, blue: 0.05098039284, alpha: 1)
var gradient = CAGradientLayer()
override init(frame: CGRect) {
super.init(frame: frame)
applyGradient()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
applyGradient()
}
func applyGradient() {
gradient.frame = self.bounds
gradient.colors = [color1,color2]
gradient.startPoint = CGPoint.zero
gradient.endPoint = CGPoint.init(x: 0.0, y: 0.5)
gradient.locations = [0,1]
self.layer.addSublayer(gradient)
}
}
I want to apply gradient vertically to my button.
It's pretty simple, here you are
@IBDesignable class GradientButton: UIButton {
@IBInspectable var topColor: UIColor = .white
@IBInspectable var bottomColor: UIColor = .black
override class var layerClass: AnyClass {
return CAGradientLayer.self
}
override func layoutSubviews() {
(layer as? CAGradientLayer)?.colors = [topColor.cgColor, bottomColor.cgColor]
}
}
Just change class from UIButton to GradientButton
