Material Motion

Reactive motion driven by Core Animation.

This library includes a variety of ready-to-use interactions. Interactions are registered to an instance of MotionRuntime:

// Store me for as long as the interactions should take effect.
let runtime = MotionRuntime(containerView: <#view#>)

	Interaction	Snippet
	ArcMove	let arcMove = ArcMove() arcMove.from.value = arcMove.to.value = runtime.add(arcMove, to: )
	ChangeDirection	runtime.add(ChangeDirection(withVelocityOf: gesture), to: )
	DirectlyManipulable	runtime.add(DirectlyManipulable(), to: )
	Draggable	runtime.add(Draggable(), to: )
	Rotatable	runtime.add(Rotatable(), to: )
	Scalable	runtime.add(Scalable(), to: )
	SetPositionOnTap	runtime.add(SetPositionOnTap(), to: runtime.get(.layer).position)
	Spring	let spring = Spring() spring.destination.value = runtime.add(spring, to: )
	Tossable	let tossable = Tossable() tossable.spring.destination.value = runtime.add(tossable, to: )
	Tween	runtime.add(Tween(duration: 0.5, values: [1, 0]), to: runtime.get(.layer).opacity)

Installation

Usage

Import the framework:

import MaterialMotion

You will now have access to all of the APIs.

Example apps/unit tests

Check out a local copy of the repo to access the Catalog application by running the following commands:

git clone https://github.com/material-motion/material-motion-swift.git
cd material-motion-swift
pod install
open MaterialMotion.xcworkspace

Case studies

Carousel

A carousel with pages that scale in and fade out in reaction to their scroll position.

View the source.

Contextual transition

A contextual view can be used to create continuity during transitions between view controllers. In this case study the selected photo is the contextual view. It’s possible to flick the view to dismiss it using the tossable interaction.

Makes use of: Draggable, Tossable, Transition, TransitionSpring, Tween.

Floating action button transition

A floating action button transition is a type of contextual transition that animates a mask outward from a floating button.

Makes use of: Transition and Tween.

View the source.

Material expansion

A Material Design transition using asymetric transformations.

Makes use of: Tween.

View the source.

Modal dialog

A modal dialog that’s presented over the existing context and is dismissable using gestures.

Makes use of: Tossable and TransitionSpring.

View the source.

Pull down to dismiss

A modal scroll view controller that can be dismissed with a drag gesture.

Makes use of: Tossable and TransitionSpring.

View the source.

Sticker picker

Each sticker is individually directly manipulable, meaning they can be dragged, rotated, and scaled using multitouch gestures.

Makes use of: DirectlyManipulable.
