Code Examples

Here are a few code examples demonstrating how to use Chatto:

1. Creating a Chat View Controller:

let chatViewController = ChatViewController(chatDataSource: chatDataSource, chatLayoutConfiguration: chatLayoutConfiguration)

2. Sending a Message:

let message = ChatItemProtocol(
    type: .text(content: "Hello, world!"),
    date: Date(),
    status: .success,
    author: .init(senderId: "user1", displayName: "User 1")
)
chatViewController.chatDataSource.appendItems([message])

3. Customizing the Chat Layout:

let chatLayoutConfiguration = ChatLayoutConfiguration(
    cellConfiguration: CellConfiguration(
        incomingMessage: IncomingMessageLayoutConfiguration(
            bubbleColor: .systemGray6,
            textColor: .black
        ),
        outgoingMessage: OutgoingMessageLayoutConfiguration(
            bubbleColor: .systemBlue,
            textColor: .white
        )
    )
)

4. Handling User Interactions:

chatViewController.chatItemTapHandler = { [weak self] item in
    if case let .text(content) = item.type {
        print("Tapped message: \(content)")
    }
}

Getting Started

To get started with Chatto, follow these steps:

1. Add the Chatto framework to your Xcode project. You can do this by using a package manager like CocoaPods or Carthage, or by manually adding the source files to your project.

2. Import the Chatto framework in your Swift file:

import Chatto

3. Create a ChatDataSource instance to manage the chat messages:

let chatDataSource = ChatDataSourceProtocol()

4. Create a ChatLayoutConfiguration instance to customize the chat UI:

let chatLayoutConfiguration = ChatLayoutConfiguration(
    cellConfiguration: CellConfiguration(
        incomingMessage: IncomingMessageLayoutConfiguration(
            bubbleColor: .systemGray6,
            textColor: .black
        ),
        outgoingMessage: OutgoingMessageLayoutConfiguration(
            bubbleColor: .systemBlue,
            textColor: .white
        )
    )
)

5. Create a ChatViewController instance and present it in your app:

let chatViewController = ChatViewController(chatDataSource: chatDataSource, chatLayoutConfiguration: chatLayoutConfiguration)
navigationController?.pushViewController(chatViewController, animated: true)

That's a basic overview of how to get started with Chatto. For more detailed information, please refer to the project's documentation.
