Components	Description
Users	Users serves as a standalone component designed to establish a screen displaying a list of users, providing them with the capability to search for specific individuals.

Messages	Messages presents the chat interface for both individual users and group entities. It exhibits a message list containing all interactions where the loggedInUser has sent or received messages from any of these entities.

Usage

Integration

Since CometChatUsersWithMessages is a view controller, it can be launched either by a button click or through any event’s trigger. It inherits all the customizable properties and methods of CometChatUsers.

View Controller: To use CometChatUsersWithMessages in your view controller, use the following code snippet.

view controller

let cometChatUsersWithMessages = CometChatUsersWithMessages()
let naviVC = UINavigationController(rootViewController: cometChatUsersWithMessages)

Actions

Actions dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.

1. SetOnItemClick

The setOnItemClick method is used to override the onClick behavior in CometChatUsersWithMessages. By default, this action has a predefined behavior which navigates to the messages. However, you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.

Swift

let cometChatUsersWithMessages = CometChatUsersWithMessages()
    .setOnItemClick { user, indexPath in
        //Perform Your Actions
}

2. SetOnItemLongClick

This method setOnItemLongClick, empowers users to customize long-click actions within CometChatUsersWithMessages, offering enhanced functionality and interaction possibilities.

Swift

let cometChatUsersWithMessages = CometChatUsersWithMessages()
    .setOnItemLongClick { user, indexPath in
         //Perform Your Actions
}

3. SetOnBack

This method allows users to override the onBack Pressed behavior in CometChatUsersWithMessages by utilizing the setOnBack , providing customization options for handling the back action.

By default, this action has a predefined behavior: it simply dismisses the current view controller. However, the flexibility of CometChat UI Kit allows you to override this standard behavior according to your application’s specific requirements. You can define a custom action that will be performed instead when the back button is pressed.

Swift

let cometChatUsersWithMessages = CometChatUsersWithMessages()
    .setOnBack {
    //Perform Your Actions
}

4. onError

This method setOnError, allows users to override error handling within CometChatUsersWithMessages, providing greater control over error responses and actions.

Swift

let cometChatUsersWithMessages = CometChatUsersWithMessages()
    .setOnError { error in
    //Perform Your Action
}
           

Filters

Filters allow you to customize the data displayed in a list within a Component. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of Chat SDK.

While the UsersWithMessages component does not have filters, its components do, For more detail on individual filters of its component refer to Users FiltersMessages Filters

By utilizing the Configurations object of its components, you can apply filters.

In the following example, we’re sorting Users by UID's and setting the limit to 10 using the usersRequestBuilder.

Swift

let usersRequestBuilder = UsersRequest.UsersRequestBuilder(limit: 20).set(UIDs: ["emma-uid"])
                        
let cometChatUsersWithMessages = CometChatUsersWithMessages(usersRequestBuilder: usersRequestBuilder)
let naviVC = UINavigationController(rootViewController: cometChatUsersWithMessages)
self.present(naviVC, animated: true)

Configurations

Configurations offer the ability to customize the properties of each component within a Composite Component.

UsersWithMessages has Users and Messages component. Hence, each of these components will have its individual `Configuration“.

• Configurations expose properties that are available in its individual components.

Users

You can customize the properties of the Users component by making use of the UsersConfiguration. You can accomplish this by employing the .set(usersConfiguration: usersConfiguration) method as demonstrated below:

Swift

let usersConfiguration = UsersConfiguration()

Usage

The UsersConfiguration is utilized within a widget housing CometChatUsersWithMessages as a child component. To configure CometChatUsersWithMessages, simply provide the usersConfiguration object using the .set(usersConfiguration:) method. This facilitates seamless customization and integration of user-specific settings within the CometChatUsersWithMessages component.

let cometChatUsersWithMessages = CometChatUsersWithMessages()
    .set(usersConfiguration: usersConfiguration)

All exposed properties of UsersConfiguration can be found under Users. Properties marked with the 🛑 symbol are not accessible within the Configuration Object.

Example

Let’s say you want to change the style of the Users subcomponent and, in addition, you only want to display users with offline status.

You can modify the style using the UsersStyle method and filter the list with the UsersRequestBuilder method.

Swift

let usersStyle = UsersStyle()

let listItemStyle = ListItemStyle()
    .set(background: .lightGray.withAlphaComponent(0.4))
        
let usersRequestBuilder = UsersRequest.UsersRequestBuilder(limit: 5).set(status: .offline)

let cometChatUsersWithMessages = CometChatUsersWithMessages(usersRequestBuilder: usersRequestBuilder)
.set(listItemStyle: listItemStyle)
cometChatUsersWithMessages.set(usersStyle: usersStyle)

let naviVC = UINavigationController(rootViewController: cometChatUsersWithMessages)
self.present(naviVC, animated: true)
