AppleEasing

AppleEasing exports easing functions that are configured to match Core Animation's timing functions. They are generally tasteful and probably make sense to use on both iOS and Android.

This library is currently supported only on React Native.

Installation

npm install react-apple-easing

Usage

The easing functions can be used with any library that pass in the elapsed time and expect an eased value back. For example, with the Animated library you could write:

let AppleEasing = require('react-apple-easing');
 
new Animated.Value(0).timing({
  easing: AppleEasing.default,
  duration: 250,
}).start();

These are the supported easing functions:

Core Animation constant	AppleEasing function
kCAMediaTimingFunctionLinear	None
kCAMediaTimingFunctionEaseIn	easeIn
kCAMediaTimingFunctionEaseOut	easeOut
kCAMediaTimingFunctionEaseInEaseOut	easeInOut
kCAMediaTimingFunctionDefault	default
