IncrementableLabel properties

var option: IncrementableLabelOptions = .linear

An options indicating how you want to perform the incrementation:

linear
easeIn
easeOut
easeInOut

typealias StringFormatter = (Float) -> String
var stringFormatter: StringFormatter?

typealias AttributedTextFormatter = (Float) -> NSAttributedString
var attributedTextFormatter: AttributedTextFormatter?

A callback closure which permits a greater control on how the text (attributed or not) is formatted between each incrementation.

var easingRate: Float = 3.0

The rate used when an option is used.

var format: String = "%d"

The format is used to set the text in the label. You can set the format to %f in order to display decimals.

public var currentValue: Double

The label’s value during the incrementation

IncrementableLabel methods

func increment(fromValue: Float, toValue: Float, duration: Float = 0.3, fromColor: UIColor? = nil, toColor: UIColor? = nil, completion: IncrementableLabelCompletion? = nil)

Starts the incrementation fromValue to toValue, and the text color changes from fromColor to toColor. The duration by default will be 0.3

func incrementFromCurrentValue(toValue: Float, duration: Float = 0.3, fromColor: UIColor? = nil, toColor: UIColor? = nil, completion: IncrementableLabelCompletion? = nil)

Starts the incrementation from the current value to toValue. The duration by default will be 0.3

func incrementFromZero(toValue: Float, duration: Float = 0.3, fromColor: UIColor? = nil, toColor: UIColor? = nil, completion: IncrementableLabelCompletion? = nil)

Starts the incrementation from zero to toValue. The duration by default will be 0.3
