Anymotion provides one unified API for animating UIKit, CoreAnimation, POP and your library of choice

• powerful oneliners
• grouping and chaining animations
• cancellable animations with callbacks for clean up
• swift api

Installation

Via CocoaPods

If you're using CocoaPods, you can simply add to your Podfile:

pod 'Anymotion', :git => 'https://github.com/agens-no/Anymotion.git', :branch => 'master'

This will download the Anymotion and dependencies in Pods/ during your next pod install exection. You may have to say pod repo update first.

Import in swift

import Anymotion

Import in Objective-C

#import <Anymotion/Anymotion.h>

Via Carthage

To install via Carthage add to your Cartfile:

github "agens-no/anymotion"

Import in swift

import Anymotion

Import in Objective-C

#import <Anymotion/Anymotion.h>

Basics

Using a chainable builder pattern we can pack a good deal of configuration in one line

let goRight = ANYPOPSpring(kPOPLayerPositionX).toValue(100).springSpeed(5).animation(for: view.layer)
let fadeOut = ANYCABasic(#keyPath(CALayer.opacity)).toValue(0).duration(1).animation(for: view.layer)

Note: These animations won't start unless you say start like this

goRight.start() fadeOut.start()

Instead of starting each one individually you can group them

goRight.groupWith(fadeOut).start()

Calling start actually returns an ANYActivity empowering you to stop the animation at any time.

let activity = goRight.groupWith(fadeOut).start() ... activity.cancel()

Frameworks integrations

POP

let spring = ANYPOPSpring(kPOPLayerPositionX) .toValue(100) .springSpeed(5) .animation(for: view.layer)

let basic = ANYPOPBasic(kPOPLayerPositionX) .toValue(100) .duration(2) .animation(for: view.layer)

let decay = ANYPOPDecay(kPOPLayerPositionX) .velocity(10) .animation(for: view.layer)

Core Animation

let basic = ANYCABasic(#keyPath(CALayer.position)) .toValue(CGPoint(x: 100, y: 0)) .duration(2) .animation(for: view.layer)

UIKit

let uikit = ANYUIView.animation(duration: 2) { view.center.x = 100 }

Operators

Grouping

Start animations simultaneously

ANYAnimation *goRight = ...; ANYAnimation *fadeOut = ...; ANYAnimation *group = [ANYAnimation group:@[goRight, fadeOut]]; [group start];

Chaining

When one animation completes then start another

ANYAnimation *goRight = ...; ANYAnimation *goLeft = ...; ANYAnimation *group = [goRight then:goLeft]; [group start];

Repeat

ANYAnimation *goRight = ...; ANYAnimation *goLeft = ...; ANYAnimation *group = [[goRight then:goLeft] repeat]; [group start];

Set up and clean up

ANYAnimation *pulsatingDot = ...; [[pulsatingDot before:^{ view.hidden = NO; }] after:^{ view.hidden = YES; }]; [pulsatingDot start];

Callbacks

ANYAnimation *anim = ...; [[anim onCompletion:^{ NSLog(@"Animation completed"); } onError:^{ NSLog(@"Animation was cancelled"); }] start];
