NoChat

NoChat is a Swift lightweight chat framework base on Chatto.
Along with NoChat, there are three companion frameworks: NoChatTG, NoChatMM, NoChatSLK.
These companion frameworks are just different user interface, you can custom your own with NoChat :].

Requirements

iOS 8.0+
Xcode 7.3 or above

Install

CocoaPods

Include the following in your Podfile:

pod 'NoChat'

Usage

Import the framework you want to use

import NoChat

You can create a subclass of ChatViewController, and provide the data.

class TGChatViewController: ChatViewController {

    // ...
    
    override func viewDidLoad() {
        inverted = true
        super.viewDidLoad()
    }

    
    // Setup chat items
    override func createPresenterBuilders() -> [ChatItemType: [ChatItemPresenterBuilderProtocol]] {
        return [
            DateItem.itemType : [
                DateItemPresenterBuider()
            ],
            MessageType.Text.rawValue : [
                MessagePresenterBuilder<TextBubbleView, TGTextMessageViewModelBuilder>(
                    viewModelBuilder: TGTextMessageViewModelBuilder(),
                    layoutCache: messageLayoutCache
                )
            ]
        ]
    }
    
    // Setup chat input views
    override func createChatInputViewController() -> UIViewController {
        let inputController = NoChatTG.ChatInputViewController()

        // ...
        
        return inputController
    }

    // ...
    
}

And I also suggest you custom the view controller of chat with the protocols provide by NoChat. I mean you can write your own ChatViewController without NoChat.ChatViewController. Source code is mind, not just code, I think.

Architechture

The architechture of the chat UI looks like this:

About the name

Why call it NoChat? Because the boss let us write many apps with chat UI, sorry I really don't want to write chat UI anymore 😢
