Message Template

Overview

A MessageTemplate provides you with the capability to define and customize both the structure and the behavior of the MessageBubble. It acts as a schema or design blueprint for the creation of a variety of MessageBubble components, allowing you to manage the appearance and interactions of MessageBubble within your application effectively and consistently.

Structure

The MessageBubble structure can typically be broken down into the following views:

Leading view: This is where the sender's avatar is displayed. It's typically on the left of the MessageBubble for messages from others and on the right for messages from the current user.
Header view: This displays the sender's name and is especially useful in group chats where multiple users are sending messages.
Reply view: This view can be used to extend the MessageBubble with additional elements. It's typically placed above the Content view.
Content view: This is the core of the MessageBubble where the message content (text, images, videos, etc.) is displayed.
Bottom view: This view can be used to extend the MessageBubble with additional elements, such as link previews or a 'load more' button for long messages. It's typically placed beneath the Content view.
Thread view:This is where the thread reply icon and reply counts are displayed. It's located below the footer view.
Footer view: This is where the timestamp of the message and its delivery or read status are displayed. It's located at the bottom of the MessageBubble.
Status Info view: This is where the timestamp of the message and its delivery or read status are displayed. It's located inside the MessageBubble just below the content view.

Properties

MessageTemplate provides you with methods that allow you to alter various properties of the MessageBubble. These properties include aspects such as the type and category of a message, the appearance and behavior of the header, content, and footer sections of the message bubble,

Type

Using setType() you can set the type of CometChatMessage, This will map your MessageTemplate to the corresponding CometChatMessage. You can set the MessageTemplates Type using the following code snippet.

let type = "custom_template"//replace this with your own custom type

//Creating a custom message template
let customMessageTemplate =
CometChatMessageTemplate(category: category, type: type, contentView: { message, alignment, controller in
return UIView() //replace this with your own UI for message list

     }, bubbleView: nil, headerView: nil, footerView: nil) { message, alignment, controller in
         return UIView() //replace this with your own UI for message composer
     } options: { message, group, controller in
         return [CometChatMessageOption]() //replace this with your own options
     }

Category

Using .setCategory() you can set the category of a MessageTemplate. This will create a MessageTemplate with the specified category and link it with a CometChatMessage of the same category.

Please refer to our guide on Message Categories for a deeper understanding of message categories.

let category = "custom_category"//replace this with your own category

//Creating a custom message template
//You can also set UI for bubbleView, headerView and footerView instead of nil
let customMessageTemplate =
  CometChatMessageTemplate(category: category, type: type, contentView: { message, alignment, controller in
         return UIView() //replace this with your own UI for message list

     }, bubbleView: nil, headerView: nil, footerView: nil) { message, alignment, controller in
         return UIView() //replace this with your own UI for message composer
     } options: { message, group, controller in
         return [CometChatMessageOption]() //replace this with your own options
     }

Header View

The .template.headerView method allows you to assign a custom header view to the MessageBubble. By default, it is configured to display the sender's name.

var allTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates()

for (index, template) in allTemplates.enumerated() {
         var template = template
         template.headerView = { (baseMessage: BaseMessage?, bubbleAlignment: MessageBubbleAlignment, viewController: UIViewController?) -> (UIView)? in
             return UIView()

  }
}

Content View

The template.contentView method allows you to assign a custom content view to the MessageBubble. By default, it displays the Text Bubble, Image Bubble, File Bubble, Audio Bubble, or Video Bubble, depending on the message type.

var allTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates()

 for (index, template) in allTemplates.enumerated() {
         var template = template
         template.contentView = { (baseMessage: BaseMessage?, bubbleAlignment: MessageBubbleAlignment, viewController: UIViewController?) -> (UIView)? in
             return UIView()
 }
}

Footer View

The template.footerView method allows you to assign a custom Footer view to the MessageBubble. By default, it displays the receipt and timestamp.

var allTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates()

 for (index, template) in allTemplates.enumerated() {
         var template = template
         template.footerView = { (baseMessage: BaseMessage?, bubbleAlignment: MessageBubbleAlignment, viewController: UIViewController?) -> (UIView)? in
             return UIView()
 }
}

Bottom View

The template.bottomView method allows you to assign a custom Bottom view to the MessageBubble.By defuault is has buttons such as link previews or a 'load more' button for long messages.

var allTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates()

 for (index, template) in allTemplates.enumerated() {
         var template = template
         template.bottomView = { (baseMessage: BaseMessage?, bubbleAlignment: MessageBubbleAlignment, viewController: UIViewController?) -> (UIView)? in
             return UIView()
 }
}

Bubble View

The template.bubbleView method allows you to assign a custom Bubble view to the MessageBubble. By default, headerView, contentView, and footerView together form a message bubble.

var allTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates()

 for (index, template) in allTemplates.enumerated() {
         var template = template
         template.bubbleView = { (baseMessage: BaseMessage?, bubbleAlignment: MessageBubbleAlignment, viewController: UIViewController?) -> (UIView)? in
             return UIView()
 }
}

Options

The template.options lets you set the list of actions that a user can perform on a message. This includes actions like reacting to, editing, or deleting a message.

var allTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates()
 for (index, template) in allTemplates.enumerated() {
         var template = template
         template.options = { message, group, controller in
             let loggedInUser = CometChat.getLoggedInUser()
             let options = CometChatUIKit.getDataSource().getMessageOptions(loggedInUser: loggedInUser!, messageObject: message!, controller: controller, group: group)

             return options
 }
  allTemplates[index] = template
}

Customization

Let's dive into how you can use the properties of MessageTemplate to customize an existing template or add a new one to the MessageList component.

The First step is to fetch the list of existing templates when you want to modify or add to them. This can be done using the getAllMessageTemplates() method from the DataSource of the CometChatUIKit class.

var messageTemplates : [CometChatMessageTemplate] = CometChatUIKit.getDataSource().getAllMessageTemplates()

Existing Templates

You will need to first get the MessageTemplates object for the type of message you want to customize. You will be customizing the TextMessage Bubble here. The code snippet to get the Text MessageTemplate is as follows.

Swift

var messageTemplates : [CometChatMessageTemplate] = CometChatUIKit.getDataSource().getAllMessageTemplates()

for i in 0..<messageTemplates.count {
 if messageTemplates[i].type == "text" && messageTemplates[i].category == "message" {
  // Set your own content view
    messageTemplates[i].contentView = { message, alignment, controller in
    // Create your own content view and return
      return UIView()
 }
   // Set your own bubble view
     messageTemplates[i].bubbleView = { message, alignment, controller in
    // Create your own bubble view and return
     return UIView()
     }
    }
 }

let cometChatMessages = CometChatMessageList()
cometChatMessages.set(templates: messageTemplates)

You will be using CometChatMessageBubble Component for example here so to apply Template to Messages you will have to use MessageList component.

By utilizing this code snippet, you will retrieve text templates.

Swift

let messageTemplates : CometChatMessageTemplate = CometChatUIKit.getDataSource().getTextMessageTemplate()

let messageListConfiguration = MessageListConfiguration()
    .set(templates: [messageTemplates])


let cometChatMessages = CometChatMessages()
    .set(user: user)
    .set(messageListConfiguration: messageListConfiguration)

info

Ensure to pass and present cometChatMessages. If a navigation controller is already in use, utilize the pushViewController function instead of directly presenting the view controller.

Header view

The template.headerView method of MessageTemplate allows you to add custom views to the header of your message bubbles. In the example below, we will add a custom UIView custom_header_view to the header view of every text message in the MessageList.

custom_header_view
import UIKit
import CometChatUIKitSwift
import UIKit

class HeaderViewStyled: UIView {
            
    private let profileImageView: UIImageView = {
        let imageView = UIImageView()
        imageView.layer.cornerRadius = 16
        imageView.clipsToBounds = true
        imageView.translatesAutoresizingMaskIntoConstraints = false
        return imageView
    }()
            
    private let nameLabel: UILabel = {
        let label = UILabel()
        label.font = UIFont.boldSystemFont(ofSize: 14)
        label.textColor = .black
        label.translatesAutoresizingMaskIntoConstraints = false
        return label
    }()
            
    private let statusLabel: UILabel = {
        let label = UILabel()
        label.font = UIFont.systemFont(ofSize: 12)
        label.textColor = .systemBlue
        label.translatesAutoresizingMaskIntoConstraints = false
        return label
    }()
            
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupView()
    }
            
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
            
    private func setupView() {
        addSubview(profileImageView)
        addSubview(nameLabel)
        addSubview(statusLabel)
                
        NSLayoutConstraint.activate([
            profileImageView.leadingAnchor.constraint(equalTo: leadingAnchor),
            profileImageView.topAnchor.constraint(equalTo: topAnchor),
            profileImageView.widthAnchor.constraint(equalToConstant: 32),
            profileImageView.heightAnchor.constraint(equalToConstant: 32),
                    
            nameLabel.leadingAnchor.constraint(equalTo: profileImageView.trailingAnchor, constant: 8),
            nameLabel.topAnchor.constraint(equalTo: topAnchor),
                    
            statusLabel.leadingAnchor.constraint(equalTo: nameLabel.trailingAnchor, constant: 4),
            statusLabel.topAnchor.constraint(equalTo: topAnchor),
        ])
    }
            
    func configure(profileImage: UIImage?, name: String, status: String) {
        profileImageView.image = profileImage
        nameLabel.text = name
        statusLabel.text = status
    }
}

Swift

Swift
var allTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates()
    for (index, template) in allTemplates.enumerated() {
    var template = template
    template.headerView = { (baseMessage: BaseMessage?, bubbleAlignment: MessageBubbleAlignment, viewController: UIViewController?) -> (UIView)? in
        let customHeaderView = HeaderViewStyled()
        return customHeaderView
       }
     allTemplates[index] = template
}                                  

let cometChatMessages = CometChatMessageList()
cometChatMessages.set(templates: allTemplates)

info

Ensure to pass and present cometChatMessages. If a navigation controller is already in use, utilize the pushViewController function instead of directly presenting the view controller.

Content view

The template.contentView method of MessageTemplate allows you to add a custom view to the content of your message bubbles. In the example below, we will add a custom custom_message_view_file to the content view of every text message in the MessageList.

Swift

custom_message_view_file
import UIKit
import CometChatSDK

        imageView.layer.cornerRadius = 8 // For rounded corners
        imageView.translatesAutoresizingMaskIntoConstraints = false
        return imageView
    }()
            
    private lazy var separatorView: UIView = {

}

let cometChatMessages = CometChatMessages()
cometChatMessages.set(templates: allTemplates)

info

Ensure to pass and present cometChatMessages. If a navigation controller is already in use, utilize the pushViewController function instead of directly presenting the view controller.

Options List

The template.options method in the MessageTemplate allows you to customize the options that appear in the action sheet when a message is long-pressed. By default, CometChat UIKit provides a set of options like "Edit", "Share", "Translated message", and "Delete".

However, if you wish to override or modify these options, you can use the template.options method and pass a list of getMessageOptions. This list of options will replace the default set.

Swift
var allTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates()
for (index, template) in allTemplates.enumerated() {
    var template = template
    template.options = { message, group, controller in
        let loggedInUser = CometChat.getLoggedInUser()
        var options = CometChatUIKit.getDataSource().getMessageOptions(loggedInUser: loggedInUser!, messageObject: message!, controller: controller, group: group)
        for (index, option) in (options ?? []).enumerated() {
            if option.id == "replyInThread" {

                let forwardOption = CometChatMessageOption(id: "customOptionId", title: "Forward", icon: UIImage(systemName: "chevron.right"))
                let favoriteOption = CometChatMessageOption(id: "favoriteOptionId", title: "Mark as Favorite", icon: UIImage(systemName: "star"))
                let deleteOption = CometChatMessageOption(id: "deleteOptionId", title: "Delete", icon: UIImage(systemName: "trash"))

                options?[index...index] = [forwardOption, favoriteOption, deleteOption]
            }
        }
        return options ?? []

    }
    allTemplates[index] = template
}    

let cometChatMessages = CometChatMessageList()
cometChatMessages.set(templates: allTemplates)

info

Ensure to pass and present cometChatMessages. If a navigation controller is already in use, utilize the pushViewController function instead of directly presenting the view controller.

Status Info View

The template.statusInfoView method of MessageTemplate enables you to add a status info view to your message bubbles. This is a user-defined component used to display the statusInfo view, which shows the timestamp and read-receipt of the message.

In the example below, we will integrate a custom UIView file named custom_status_view into the status info view of every text message in the MessageList.

custom_status_view
import UIKit
import CometChatSDK
import CometChatUIKitSwift

class StatusInfoView: UIView {
    
    private let timeLabel: UILabel = {
        let label = UILabel()

        label.textColor = .gray
        label.font = UIFont.systemFont(ofSize: 12)
        label.translatesAutoresizingMaskIntoConstraints = false
        return label
    }()
    
    private let doubleTickImageView: UIImageView = {
        let imageView = UIImageView()
        imageView.image = UIImage(named: "double_tick") // Add your double tick image here
        imageView.contentMode = .scaleAspectFit
        imageView.translatesAutoresizingMaskIntoConstraints = false
        return imageView
    }()
    
    private let timeStackView: UIStackView = {
        let stackView = UIStackView()
        stackView.axis = .horizontal
        stackView.spacing = 4
        stackView.alignment = .center
        stackView.translatesAutoresizingMaskIntoConstraints = false
        return stackView
    }()

            if textMessage.readAt > 0 {
                status = "Read"
                doubleTickImageView.image = UIImage(named: "message-read")
            } else if textMessage.deliveredAt > 0 {

                doubleTickImageView.image = UIImage(named: "double-tick")
            }

            let dateFormatter = DateFormatter()

        }
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

                    return CustomStatusView(baseMessage: baseMessage)
                }
                return nil
        }
    allTemplates[index] = template
}

let cometChatMessages = CometChatMessages()
cometChatMessages.set(templates: allTemplates)

info

Ensure to pass and present cometChatMessages. If a navigation controller is already in use, utilize the pushViewController function instead of directly presenting the view controller.

New Template

You can create an entirely new template for custom messages is one of the powerful features of CometChat's MessageTemplate. To add a new template, you can create a new one and then add it to the list of existing templates.

First, let's see how to send a custom message:

Swift
//Creating a text template
let textTemplate = CometChatUIKit.getDataSource()
                      .getTextMessageTemplate()

// set content view for TextMessage template
textTemplate.contentView = { message, alignment, controller in
	// Create your own content view and return
  return UIView()
}

// set bubble view for TextMessage template
textTemplate.bubbleView = { message, alignment, controller in
  // Create your own bubble view and return
  return UIView()
}

//Creating an audio template
let audioTemplate = CometChatUIKit.getDataSource()
                      .getAudioMessageTemplate()

// set content view for AudioMessage template
audioTemplate.contentView = { message, alignment, controller in
	// Create your own content view and return
  return UIView()
}

// set bubble view for AudioMessage template
audioTemplate.bubbleView = { message, alignment, controller in
  // Create your own bubble view and return
  return UIView()
}


let type = "custom_template"//replace this with your own custom type
let category = "custom_category"//replace this with your own category

//Creating a custom message template
//You can also set UI for bubbleView, headerView and footerView instead of nil
let customMessageTemplate =
     CometChatMessageTemplate(category: category, type: type, contentView: { message, alignment, controller in
            return UIView() //replace this with your own UI for message list

        }, bubbleView: nil, headerView: nil, footerView: nil) { message, alignment, controller in
            return UIView() //replace this with your own UI for message composer
        } options: { message, group, controller in
            return [CometChatMessageOption]() //replace this with your own options
        }

//custom list of templates
let messageTypes = [
        textTemplate,
        audioTemplate,
   		customMessageTemplate
              ]

var templates = [(type: String, template: CometChatMessageTemplate)]()
for template in messageTypes {
	templates.append((type: template.type, template: template))
}

//passing template list to cometchatMessages
  let messageList = CometChatMessageList()
	messageList.set(templates: templates)

Find the example below:

        imageView.image = UIImage(named: "profile_placeholder") // Replace with your image
        return imageView
    }()
    
    private let nameLabel: UILabel = {
        let label = UILabel()
