Magic CollectionView

A physics-enabled UICollectionViewLayout that strives to create a "magic" feeling while scrolling. The smoothly animated movement of the items is achieved by using the UIKit Dynamics Engine.

Download the sample project to see it in action and scroll through a list of yummy vegetables.

Demo

Easy tweaking of the physics behavior

Tweak the translation of scroll distance into item movement

• by setting a scrollResistance
• by setting a maximum shift along the y-axis or leaving it unlimited (set to nil)

Tweak the spring that attaches the item to its anchor point

• by changing the length of attachment (distance between item and its anchor point) (0.0 to infinity)
• by changing the damping of the spring (0.0 to 1.0)
• by changing the oscillation frequency (0.0 to infinity)
• by changing the friction torque (0.0 to infinity)

Usage

Simply add it to your project in two steps:

1. Add the MagicCollectionViewFlowLayout file.
2. Set your collectionView's layout to an instance of MagicCollectionViewFlowLayout.
