Rainbows is a Metal-backed alternative to CAGradientLayer that is incredibly fast. It provides drawing of axial (aka "linear"), radial (aka "circular"), sweep (aka "angular" aka "conical") and even trippy spiral gradients at no less than 60fps.
Let's say you want to add a trippy noir spiral gradient to your view:
import Rainbows
let gradientLayer = GradientLayer()
gradientLayer.gradient = Gradient(colors: [
UIColor.black.cgColor, UIColor.white.cgColor
])
gradientLayer.configuration = .spiral(
center: CGPoint(x: 0.5, y: 0.5),
angle: 0.0 * CGFloat.pi * 2.0,
scale: 1.0
)
gradientLayer.frame = view.layer.bounds
view.layer.addSublayer(gradientLayer)Or just skip the detour via self.layer and use a convenient GradientView:
import Rainbows
let gradientView = GradientView()
gradientView.gradient = Gradient(colors: [
UIColor.black.cgColor, UIColor.white.cgColor
])
gradientView.configuration = .spiral(
center: CGPoint(x: 0.5, y: 0.5),
angle: 0.0 * CGFloat.pi * 2.0,
scale: 1.0
)The recommended way to add Rainbows to your project is via Carthage:
