RVS_RetroLEDDigitalDisplay

@IBDesignable
open class RVS_RetroLEDDigitalDisplay : UIImageView

The display is a subclass of UIImageView. We do this, so we can easily have a background image.

Public Computed Properties

  • This allows you to apply a “skew” to the widget. This means that there is a “lean,” like many classic LED displays. A positive skew, means that the widget “leans right,” with the top moving right, and the bottom, moving left. A negative skew, is in the other direction. This is limited to -1…1. This will change the size of the widget, horizontally (but not vertically).

    Declaration

    Swift

    @IBInspectable
var skew: CGFloat { get set }

  • This is the duration of change animations. Default is 1/8 of a second (125 mS). 0 disables the animation.

    Declaration

    Swift

    @IBInspectable
var animationDurationInSeconds: CGFloat { get set }

  • The starting color for the “On” gradient.

    Declaration

    Swift

    @IBInspectable
var onGradientStartColor: UIColor? { get set }

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

    Declaration

    Swift

    @IBInspectable
var onGradientEndColor: 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 onGradientAngleInDegrees: CGFloat { get set }

  • The starting color for the “Off” gradient.

    Declaration

    Swift

    @IBInspectable
var offGradientStartColor: UIColor? { get set }

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

    Declaration

    Swift

    @IBInspectable
var offGradientEndColor: 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 offGradientAngleInDegrees: CGFloat { get set }

  • This is true, if values are to be displayed with leading zeores.

    Declaration

    Swift

    @IBInspectable
var hasLeadingZeroes: Bool { get set }

  • This is the number of digits for this group. 0 (or less), means no display.

    Declaration

    Swift

    @IBInspectable
var numberOfDigits: Int { get set }
  • gap

    This is how many calculation (not display) units separate each digit. Default is 8.

    Declaration

    Swift

    @IBInspectable
var gap: CGFloat { get set }

  • This property allows you to assign an image to the on segments. If this is set to an image (non-nil), then that will supersede the gradient colors.

    Declaration

    Swift

    @IBInspectable
var onImage: UIImage? { get set }

  • This is a numerical value to set to the collected digits. If we have an animation duration, the old value will fade.

    Declaration

    Swift

    @IBInspectable
var value: Int { get set }

  • Read-only value that returns the minimum possible value for this instance (always -2).

    Declaration

    Swift

    var minValue: Int { get }

  • Read-only value that returns the maximum possible value for this instance.

    Declaration

    Swift

    var maxValue: Int { get }

  • The ideal aspect ratio (X / Y) of the display.

    Declaration

    Swift

    var idealAspect: CGFloat { get }

  • The numerical base of the display (2, 8, 10, 16). 16 is default. If you set a different radix from the ones listed, the set will be refused.

    Declaration

    Swift

    var radix: Int? { get set }

Public Base Class Overrides

  • This property allows you to assign an image to the off segments. If this is set to an image (non-nil), then that will supersede the gradient colors.

    Declaration

    Swift

    override var image: UIImage? { get set }

  • Called when the views are to be laid out. Most of the action happens here.

    Declaration

    Swift

    override func layoutSubviews()
