Deprecation
This library is deprecated in favor of iOS 12 CAGradientLayer layer type .conic
See ConicSample project for CAGradientLayer examples ported from AngleGradientLayer.
AngleGradientLayer
AngleGradientLayer is a CALayer implementation of angle gradient.
Installing
pod 'AngleGradientLayer', '~> 1.0'[Swift] Using in your code
import AngleGradientLayer

override class func layerClass() -> AnyClass {
return AngleGradientLayer.self

let l: AngleGradientLayer = self.layer as! AngleGradientLayer

UIColor(red: 1, green: 1, blue: 0.4, alpha: 1).CGColor]

@endNotes
When working with semi-transparent views, be sure to set backgroundColor property on the layer's view
myview.backgroundColor = UIColor.clearColor()backgroundColor by default is nil, blending to black color.
