MJParallax Collection View

Abstract

1. Introduction

This is a parallax for the cells inside UICollectionView. It gives us an effect just like scrolling the images in Whatsapp or scrolling through the Weather app for iOS.

Optionally, you can change the animation speed for the images or the height of the images in the UICollectionViewCell by chnaging the constants used in MJCollectionViewCell.h
