GradientView

public final class GradientView: UIView

A gradient view that acts as the background of any ColorSlider. This class draws colors based on the orientation passed to the initializer and determines the output color of ColorSlider after a touch event.

Customize the appearance of ColorSlider by setting layer properties on this class, including borderWidth, borderColor, and cornerRadius.

  • Whether the gradient should adjust its corner radius based on its bounds. When true, the layer’s corner radius is set to min(bounds.width, bounds.height) / 2.0 in layoutSubviews.

    Declaration

    Swift

    public var automaticallyAdjustsCornerRadius: Bool = true

  • The saturation of all colors in the view. Defaults to 1.

    Declaration

    Swift

    public var saturation: CGFloat = 1

  • The percent of space at the beginning (top for orientation .vertical and left for orientation .horizontal) end of the slider reserved for the color white. Defaults to 0.15.

    Declaration

    Swift

    public var whiteInset: CGFloat = 0.15

  • The percent of space at the end (bottom for orientation .vertical and right for orientation .horizontal) end of the slider reserved for the color black. Defaults to 0.15.

    Declaration

    Swift

    public var blackInset: CGFloat = 0.15

  • Declaration

    Swift

    required public init(orientation: Orientation)

    Parameters

    orientation

    The orientation of the gradient view.
