Simple Interface Core Animation

Sica can execute various animations sequentially or parallelly.

Features

• Animation with duration and delay
• parallel / sequence animation
• Easings
• Springs
• Transition

Requirements

• Xcode 9.3 or greater
• iOS 9 or greater
• tvOS 10.0 or greater
• macOS 10.11 or greater
• Swift 4.2 (since 0.3.4)

Installation

Carthage

If you’re using Carthage, simply add Sica to your Cartfile:

github "cats-oss/Sica"

CocoaPods

Sica is available through CocoaPods. To instal it, simply add the following line to your Podfile:

pod 'Sica'

Swift Package Manager

Sica is available through SwiftPM, create Package.swift and add dependencies value

dependencies: [
    .package(url: "https://github.com/cats-oss/Sica.git", from: "0.4.1")
]

Usage

Sample Animation

Sequence Animation

If you set .sequence, sequence animation is shown.

let animator = Animator(view: sampleView)
animator
    .addBasicAnimation(keyPath: .positionX, from: 50, to: 150, duration: 2, timingFunction: .easeOutExpo)
    .addSpringAnimation(keyPath: .boundsSize, from: sampleView.frame.size, to: CGSize(width: 240, height: 240), damping: 12, mass: 1, stiffness: 240, initialVelocity: 0, duration: 1)
    .run(type: .sequence)

Parallel Animation

If you set .parallel, parallel animation is shown.

let animator = Animator(view: sampleView)
animator
    .addBasicAnimation(keyPath: .positionX, from: 50, to: 150, duration: 5, timingFunction: .easeOutExpo)
    .addBasicAnimation(keyPath: .transformRotationZ, from: 0, to: CGFloat.pi, duration: 3, timingFunction: .easeOutExpo)
    .run(type: .parallel)

Forever Animation

If you set forever before calling run, forever animation is shown.

let animator = Animator(view: sampleView)
animator
    .addBasicAnimation(keyPath: .positionX, from: 50, to: 150, duration: 2, timingFunction: .easeOutExpo)
    .addBasicAnimation(keyPath: .positionX, from: 150, to: 50, duration: 2, timingFunction: .easeOutExpo)
    .forever(autoreverses: false)
    .run(type: .sequence)

Cancel

If you want to cancel animation, you should call cancel.

let animator = Animator(view: sampleView)
/*
Add animation and run
*/
animator.cancel() // Animation cancel

Remove Added Animations

If you call run and then you call add animation method, no animation will be added. If you use animator again, you call removeAll before addBasicAnimation or addSpringAnimation or addTransitionAnimation.

let animator = Animator(view: sampleView)
/*
Add animation and run
*/

// Bad
animator.addBasicAnimation() // 🙅 you can't add animation

// Good
animator.removeAll()
        .addBasicAnimation() // 🙆 You can add animation.

Functions

Add Animation

    public func addBasicAnimation<T>(keyPath: Sica.AnimationKeyPath<T>, from: T, to: T, duration: Double, delay: Double = default, timingFunction: Sica.TimingFunction = default) -> Self where T : AnimationValueType
    public func addSpringAnimation<T>(keyPath: Sica.AnimationKeyPath<T>, from: T, to: T, damping: CGFloat, mass: CGFloat, stiffness: CGFloat, initialVelocity: CGFloat, duration: Double, delay: Double = default, timingFunction: Sica.TimingFunction = default) -> Self where T : AnimationValueType
    public func addTransitionAnimation(startProgress: Float, endProgress: Float, type: Sica.Transition, subtype: Sica.TransitionSub, duration: Double, delay: Double = default, timingFunction: Sica.TimingFunction = default) -> Self

Add Animation Option

    public func delay(_ delay: Double) -> Self
    public func forever(autoreverses: Bool = default) -> Self

Animation Operation

    public func run(type: Sica.Animator.AnimationPlayType, isRemovedOnCompletion: Bool = default, completion: (() -> Swift.Void)? = default)
    public func cancel()
    public func removeAll() -> Self

Extensions

You can access sica property in UIView and CALayer.

let view = UIView(frame: ...)
view.sica
    .addBasicAnimation(keyPath: .positionX, from: 50, to: 150, duration: 2, timingFunction: .easeOutExpo)
    .run(type: .sequence)

let layer = CALayer()
layer.sica
    .addBasicAnimation(keyPath: .positionX, from: 50, to: 150, duration: 2, timingFunction: .easeOutExpo)
    .run(type: .sequence)
