I extended UIView to add a addGradientWithColor() method to get the gradient background:
extension UIView {
func addGradientWithColor() {
let gradient = CAGradientLayer()
gradient.frame = self.bounds
gradient.colors = [gradientEndColor.CGColor, gradientStartColor.CGColor]
gradient.startPoint = CGPointMake(1,0)
gradient.endPoint = CGPointMake(0.2,1)
self.layer.insertSublayer(gradient, atIndex: 0)
} }
My issue is when I run landscape mode, the UIView is not stretched
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
self.view.addGradientWithColor() }
I tried to calling viewDidLayoutSubviews() but its not working properly
You can subclass the UIView and override drawRect method where you add your gradient.
Updated to Swift 4
class GradientView: UIView {
private let gradient : CAGradientLayer = CAGradientLayer()
private let gradientStartColor: UIColor
private let gradientEndColor: UIColor
init(gradientStartColor: UIColor, gradientEndColor: UIColor) {
self.gradientStartColor = gradientStartColor
self.gradientEndColor = gradientEndColor
super.init(frame: .zero)
}
required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") }
override func layoutSublayers(of layer: CALayer) {
super.layoutSublayers(of: layer)
gradient.frame = self.bounds
}
override public func draw(_ rect: CGRect) {
gradient.frame = self.bounds
gradient.colors = [gradientEndColor.cgColor, gradientStartColor.cgColor]
gradient.startPoint = CGPoint(x: 1, y: 0)
gradient.endPoint = CGPoint(x: 0.2, y: 1)
if gradient.superlayer == nil {
layer.insertSublayer(gradient, at: 0)
}
}
}
After you create your UIView you just need to add your constraints to that view.
