 1 | # MOTickerLabel
 2 | 
 3 | Ticker Label that animates changes in monetary value. To learn more about how `MOTickerLabel` works, checkout this [Mosaic Enginnering blog post](https://blog.getmosaic.io/The-Ticker).
 4 | 
 5 | > The label currently only supports US dollar.
 6 | 
 7 | ## Sample Code
 8 | 
 9 | ```swift
10 | let label = TickerLabel(frame: CGRect(x: 0, y: 0, width: 300, height: 50), value: Dollar(float: 12.03))
11 | view.addSubview(label)
12 | label.value = Dollar(float: 10.19)
13 | 
14 | // Animate change after two seconds!
15 | DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
16 |     self.label.value = Dollar(float: 940.39)
17 | }
18 | ```
