Messages (iOS)

Messages app prototype for iOS

Notice: current state of the project is "for R&D purposes only"

Description

Disappointed with availabe libraries and components for replicating Messages app UI in iOS application, I decided to create my own solution. It shows how to build chat-alike user interface that allows sending and receiving messages. It's not "one size fits all", not perfect nor optimal. It's definately much simplier than some messaging-UI libraries, and because of this, easier to maintain and customize. Messages list is build using UICollectionView managed by IGListKit library. There is no backend logic in this project - app uses mocked up service that simulates communication with server side.

Special thanks to turekj for help with developing simple solution to preserve UIScrollView content offset when reloading data.

What's inside

• UICollectionView managed by IGListKit
• UICollectionViewLayout that displays cells from bottom to top
• Custom UICollectionViewCell for representing messages on the list
• Workaround for preserving content offset when adding cells to UICollectionView
• Pagination with UIRefreshControl that allows loading messages history
• Custom toolbar for composing new messages
• Mocked up service that simulates communication with backend
