The main idea of this converter is adopt the same gradient from Web to iOS. The CSS has linear-gradient() func to create gradient.
background: linear-gradient(-275DEG, red, yellow); background: linear-gradient(35deg, red, yellow); background: linear-gradient(680deg, red, yellow);Unlike UIKit has another coordinate subsystem for CGGradientLayer:
gradientLayer.startPoint = CGPoint(x:0, y:0.559) gradientLayer.endPoint = CGPoint(x:1, y:0.441) // and so on
let size = CGSize(width: 200, height: 100) let gradient = CAGradientLayer() gradient.frame = CGRect(x: 0, y: 0, width: size.width, height: size.height) gradient.colors = [UIColor.red.cgColor, UIColor.yellow.cgColor] let points = gradientPoints(size: gradient.bounds.size, cssAngle: -275) gradient.startPoint = points.start gradient.endPoint = points.endCSSGradientToUIKit is released under the MIT License.
