ChatLayout is an alternative solution to MessageKit. It uses custom
UICollectionViewLayout to provide you full control over the presentation as well as all the tools available in
- Supports dynamic cells and supplementary view sizes.
- Animated insertion/deletion/reloading/moving of the items.
- Keeps content of the last visible item at the top or bottom of the
- Provides tools for precise scrolling to the required item.
- Shipped with generic container views to simplify the custom items implementation.
What ChatLayout doesnt provide (And why it is good)
ChatLayout is the custom
You don't have to extend or override any custom
UICollectionView. You need to instantiate them yourself and use them the way you like.
ChatLayoutdoes not rely on modified
UICollectionViewFlowLayoutnor does it rotate your
UICollectionViewupside-down. This means you can use your views as if they would be regular cells within
UICollectionView. You can benefit from using the default
adjustedContextInsets(and others) because your view controller is a normal view controller without any hacks or tricks.
ChatLayoutdoesn't require you to calculate all the cell sizes before it renders them on the screen. You can fully use auto-layout constraints and rely on the fact that the correct size will be calculated in the runtime. However,
ChatLayoutas any other
UICollectionViewLayoutwill benefit from you providing the estimated sizes of your cells as it will allow you to get better performance.
ChatLayoutdoesn't enforce you to use any specific data model. You can store your messages and update
UICollectionViewthe way you like. The only thing you need is to respect the natural boundaries that
UICollectionViewhave and correctly implement
ChatLayoutdoesn't enforce you to use any specific
UIViews to create your collection cells. You can create them the way you like. It can be any
UICollectionReusableView. There are some generic
UIViews bundled with the library that may help you to build them faster. However, you do not have to use them.
ChatLayoutdoesn't handle the keyboard appearance behavior. You have to implement that yourself from scratch or use the library you are already using in your project. It gives you full control over the keyboard presentation. The only thing you have to do is to update the
ChatLayoutdoesn't provide you any input control. You can use any one you like and customise it the way you like. The Example app for instance uses InputBarAccessoryView.
To run the example project, clone the repo, and run
