# mayuur/MJParallaxCollectionView

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

## What it is
An Objective-C library that adds a parallax scrolling effect to cells inside a UICollectionView, mimicking the image scrolling seen in WhatsApp or the iOS Weather app. It is integrated by setting up standard UICollectionView datasource/delegate methods and the scrollViewDidScroll callback.

## Use cases
- add parallax scrolling to collection view images in an iOS app
- recreate the WhatsApp image scrolling effect
- build a weather-app-style scrolling image gallery
- animate collection view cells while scrolling
- make image cells move at different speeds during scroll

## When to choose
- you are building an Objective-C or legacy iOS app with UICollectionView and want a quick parallax effect
- you want a lightweight drop-in effect with minimal setup
- you need a simple MIT-licensed parallax implementation to study or customize

## When to avoid
- you are starting a new Swift project and prefer Swift-native or SwiftUI solutions
- you need actively maintained or regularly updated libraries
- you need parallax effects outside UICollectionView or on non-iOS platforms

## Facets
