ACAnimator
ACAnimator lets you animate almost anything on iOS or tvOS (including non-animatable properties). Can also be used to "animate" logical changes not just visual (e.g. fade in/out audio). It supports over 30 different easing functions and it uses CADisplayLink for optimal performance.
Example
To run the example project, clone the repo, and run pod install from the Example directory first.
Usage
// A random element
let box = UIView(frame: CGRect(x: 0, y: 200, width: 40, height: 40))
box.backgroundColor = .red
view.addSubview(box)
// Determine the target value
let targetX = UIScreen.main.bounds.width - box.frame.width
// Prepare and run the animation
let animator = ACAnimator(duration: 3.0, easeFunction: .expoInOut, animation: { (fraction, _, _) in
// Calculate the proper value for the current "frame"
let newValue = targetX * CGFloat(fraction)
// Apply the new value
box.transform = CGAffineTransform(translationX: newValue, y: 0)
// NOTE: the `transform` property is animatable through UIKit or CoreAnimation, this example just showcases the equivalent implementation using ACAnimator.
})
