Original

AnimatedCollectionViewLayout

Normally a UICollectionView has no transition effects when you scroll from one item to another. There are lots of ways to write animations for UICollectionView, but using a UICollectionViewLayout subclass is by far the simplest one. And it doesn't break any of your existing code. You can still use your UICollectionView subclass and you don't need to change your UICollectionViewCell. Just plug and enjoy.

pod 'AnimatedCollectionViewLayout'

For Swift 4.1 or below:

pod 'AnimatedCollectionViewLayout', '~> 0.3.0'

Usage

Get Started

Import the library where you want to use it. Create a AnimatedCollectionViewLayout object, set its animator and assign it to your UICollectionView.

import AnimatedCollectionViewLayout

// ...

let layout = AnimatedCollectionViewLayout()
layout.animator = ParallaxAttributesAnimator()
collectionView.collectionViewLayout = layout

Customization

Most of the built-in animators work best in Paging mode and they have additional parameters that you can tweak for better transitions. You can also write your own animators by implementing the protocol LayoutAttributesAnimator.
