RVS_MaskButton

@IBDesignable
open class RVS_MaskButton : UIButton

Public Computed Properties

  • This allows you to set the font of the button. This is not inspectable, and must be set programmatically.

    Declaration

    Swift

    var buttonFont: UIFont? { get set }

  • The starting color for the gradient. If not provided, the view backgroundColor is used. If that is not provided, then the view tintColor is used. If that is not provided, then the super (parent) view tintColor is used. If that is not provided, the AccentColor is used. If that is not provided, the class will not work.

    Declaration

    Swift

    @IBInspectable
var gradientStartColor: UIColor? { get set }

  • The ending color. If not provided, then the starting color is used.

    Declaration

    Swift

    @IBInspectable
var gradientEndColor: UIColor? { get set }

  • The angle of the gradient, in degrees. 0 (default) is top-to-bottom. Zero is top-to-bottom. Negative is counter-clockwise, and positive is clockwise.

    Declaration

    Swift

    @IBInspectable
var gradientAngleInDegrees: CGFloat { get set }

  • If true, then the label is reversed, so the background is “cut out” of the foreground. If there is a border, that will also be cut out.

    Declaration

    Swift

    @IBInspectable
var reversed: Bool { get set }

  • This allows access to the border width.

    Declaration

    Swift

    @IBInspectable
var borderWidthInDisplayUnits: CGFloat { get set }
