Usage

CountingLabel is subclass of UILabel, just use it as UILabel. Call count(fromValue: CGFloat, toValue: CGFloat, duration: TimeInterval = 2, option: AnimationOption = .linear) to start the animation.

Format

There are two ways to set the format of your label:

• Set label.format like "%.0f".
• Implement CountingLabelValueFormatter like PercentFormatter in the demo, and set label.valueFormatter to an instance of that.

valueFormatter has higher priority than label.format

AnimationOption

CountingLabel support four kind of changing rate, and default is linear. Pass argument option in method count(fromValue: CGFloat, toValue: CGFloat, duration: TimeInterval = 2, option: AnimationOption = .linear) to change that. Avaliable options are:

public enum AnimationOption {
    case linear
    case easeIn
    case easeOut
    case easeInOut
}
