ScrollCounter is available through CocoaPods. To install it, simply add the following line to your Podfile:
ScrollCounter is a framework for getting a nice scrolling animation when transitioning between numbers. This framework is modeled after the animations seen in the Robinhood app.
Checkout this Medium article for a high-level look on how ScrollCounter works.
// Initialize a scrolling counter for the standard range between 0-9 (other ranges can be used as well). let singleDigit = DigitScrollCounter(font: UIFont(name: "Avenir-Black", size: 150)!, textColor: .white, backgroundColor: .black, scrollDuration: 0.3, gradientColor: .black, gradientStop: 0.2) // Scrolls to the item at the 8th index. For a DigitScrollCounter, this means scroll to the number 8. singleDigit.scrollToItem(atIndex: 8)
// Initialize a number counter, which is a view composed of `DigitScrollCounter`s. let numberCounter = NumberScrollCounter(value: 1, scrollDuration: 0.33, decimalPlaces: 2, prefix: "$", suffix: "", font: font.withSize(40), textColor: .white, gradientColor: .black, gradientStop: 0.2) // Set a new value. This will trigger the animation to show the given value. numberCounter.setValue(123.45)
