Groups - CometChat Docs

Overview

CometChatGroups functions as a standalone component designed to create a screen displaying a list of groups, with the added functionality of enabling users to search for specific groups. Acting as a container component, CometChatGroups encapsulates and formats the CometChatListBase and CometChatGroupList components without introducing any additional behavior of its own.

The Groups component is composed of the following BaseComponents:

Components	Description
CometChatListBase	`CometChatListBase` serves as a container component equipped with a title (navigationBar), search functionality (search-bar), background settings, and a container for embedding a list view.
CometChatListItem	This component renders information extracted from a `Group` object onto a tile, featuring a title, subtitle, leading view, and trailing view.

Usage

Integration

The following code snippet illustrates how you can can launch CometChatGroups.

Swift

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

If you are already using a navigation controller, you can use the pushViewController function instead of presenting the view controller.

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

This method proves valuable when users seek to override onItemClick functionality within CometChatGroups, empowering them with greater control and customization options. The setOnItemClick action doesn’t have a predefined behavior. You can override this action using the following code snippet.

Swift

let groups = CometChatGroups()
.setOnItemClick (onItemClick:{ group, indexPath in
//Perform Your Action       
})

2. SetOnItemLongClick

This method becomes invaluable when users seek to override long-click functionality within CometChatGroups, offering them enhanced control and flexibility in their interactions. The setOnItemLongClick action doesn’t have a predefined behavior. You can override this action using the following code snippet.

Swift

let groups = CometChatGroups()
.setOnItemLongClick (onItemLongClick:{ group, indexPath in
//Perform Your Action
})

3. SetOnError

You can customize this behavior by using the provided code snippet to override the On Error and improve error handling.

Swift

let groups = CometChatGroups()
    .setOnError (onError:{ error in
    //Perform Your Action
})

4. SetOnBack

Enhance your application’s functionality by leveraging the SetOnBack feature. This capability allows you to customize the behavior associated with navigating back within your app. Utilize the provided code snippet to override default behaviors and tailor the user experience according to your specific requirements.

Swift

let groups = CometChatGroups()
    .setOnBack (onBack:{
    //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.

1. GroupsRequestBuilder

The GroupsRequestBuilder enables you to filter and customize the group list based on available parameters in GroupsRequestBuilder. This feature allows you to create more specific and targeted queries when fetching groups. The following are the parameters available in GroupsRequestBuilder

Methods	Type	Description
setLimit	Int	Configure the maximum number of groups to fetch in a single request, optimizing pagination for smoother navigation.
setSearchKeyword	String	Employed to retrieve groups that match the provided string, facilitating precise searches.
joinedOnly	boolean	Exclusively fetches joined groups.
setTags	[String]	Utilized to fetch groups containing the specified tags.
withTags	boolean	Utilized to retrieve groups with specific tags.

Example In the example below, we are applying a filter to the Group List based on only joined groups.

Swift

// You can create GroupRequestBuilder as per your requirement
let groupsRequestBuilder = GroupsRequest.GroupsRequestBuilder(limit: 20).set(joinedOnly: true)

let groups = CometChatGroups(groupsRequestBuilder: groupsRequestBuilder)
let naviVC = UINavigationController(rootViewController: groups)
self.present(naviVC, animated: true)

2. SearchRequestBuilder

The SearchRequestBuilder uses GroupsRequestBuilder enables you to filter and customize the search list based on available parameters in GroupsRequestBuilder. This feature allows you to keep uniformity between the displayed Groups List and searched Group List. Example

Swift

// You can create GroupRequestBuilder as per your requirement
let groupsRequestBuilder = GroupsRequest.GroupsRequestBuilder(limit: 2).set(searchKeyword: "")

let groups = CometChatGroups(groupsRequestBuilder: groupsRequestBuilder)
let naviVC = UINavigationController(rootViewController: groups)
self.present(naviVC, animated: true)

Events

Events are emitted by a Component. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed. The list of events emitted by the Groups component is as follows.

Event	Description
onGroupCreate	This gets triggered when the logged in user creates a group.
onGroupDelete	This gets triggered when the logged in user deletes a group.
onGroupMemberLeave	This gets triggered when the logged in user leaves a group.
onGroupMemberChangeScope	This gets triggered when the logged in user changes the scope of another group member.
onGroupMemberBan	This gets triggered when the logged in user bans a group member from the group.
onGroupMemberKick	This gets triggered when the logged in user kicks another group member from the group.
onGroupMemberUnban	This gets triggered when the logged in user unbans a user banned from the group.
onGroupMemberJoin	This gets triggered when the logged in user joins a group.
onGroupMemberAdd	This gets triggered when the logged in user adds new members to the group.
onOwnershipChange	This gets triggered when the logged in user transfers the ownership of their group to some other member.

Adding CometChatGroupsEvents Listener’s

         CometChatGroupEvents.addListener("UNIQUE_ID", self as CometChatGroupEventListener)
    }

}

 // Listener events from groups module
extension  ViewController: CometChatGroupEventListener {

    public func onGroupMemberAdd(group: Group, members: [GroupMember], addedBy: User) {
        // Do Stuff
    }

Advanced

For advanced-level customization, you can set custom views to the component. This lets you tailor each aspect of the component to fit your exact needs and application aesthetics. You can create and define your views, layouts, and UI elements and then incorporate those into the component.

ListItemView

Utilize this property to assign a custom ListItem to the Groups Component, allowing for enhanced customization and flexibility in its rendering.

Swift

let groups = CometChatGroups()
    .setListItemView(listItemView: { group in
    //Perform Your Action
})

Example

In this example, we will create a UIView file CustomListItemGroupView and pass it inside the setListItemView() method.

CustomListItemGroupView

import UIKit
import CometChatSDK
import CometChatUIKitSwift

class CustomListItemGroupView: UIView {
    // Initialize your subviews
    let titleLabel: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.font = UIFont.boldSystemFont(ofSize: 16)
        return label
    }()

    let statusIndicator: UIView = {
        let view = UIView()
        view.translatesAutoresizingMaskIntoConstraints = false
        view.backgroundColor = .green
        view.layer.cornerRadius = 5
        return view
    }()

    let groupImageView: CometChatAvatar = {
        let imageView = CometChatAvatar(frame: .zero)
        imageView.translatesAutoresizingMaskIntoConstraints = false
        return imageView
    }()

    // Override the initializer
    override init(frame: CGRect) {
        super.init(frame: frame)
        // Add subviews and layout constraints
        addSubview(groupImageView)
        addSubview(titleLabel)
        addSubview(statusIndicator)

        NSLayoutConstraint.activate([
            groupImageView.leadingAnchor.constraint(equalTo: leadingAnchor, constant: 8),
            groupImageView.centerYAnchor.constraint(equalTo: centerYAnchor),
            groupImageView.heightAnchor.constraint(equalToConstant: 40),
            groupImageView.widthAnchor.constraint(equalToConstant: 40),

            titleLabel.centerYAnchor.constraint(equalTo: centerYAnchor),
            titleLabel.leadingAnchor.constraint(equalTo: groupImageView.trailingAnchor, constant: 8),
            titleLabel.trailingAnchor.constraint(equalTo: trailingAnchor, constant: -8),

            statusIndicator.widthAnchor.constraint(equalToConstant: 10),
            statusIndicator.heightAnchor.constraint(equalToConstant: 10),
            statusIndicator.trailingAnchor.constraint(equalTo: titleLabel.trailingAnchor),
            statusIndicator.bottomAnchor.constraint(equalTo: titleLabel.bottomAnchor)
        ])
    }

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

    // Configure the view with a group
    func configure(with group: CometChatSDK.Group) {
        titleLabel.text = group.name
        statusIndicator.backgroundColor = group.hasJoined ? .green : .gray
        groupImageView.setAvatar(avatarUrl: group.icon ?? "", with: group.name ?? "")
    }
}

Swift

let groups = CometChatGroups()
    .setListItemView(listItemView: { group in
        let customListItemGroupView = CustomListItemGroupView()
        customListItemGroupView.configure(with: group!)
        return customListItemGroupView
})

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

SubtitleView

You can set your custom Subtitle view using the .setSubtitleView() method. But keep in mind, by using this you will override the default Subtitle view functionality.

Swift

let groups = CometChatGroups()
    .setSubtitleView (subtitle:{ group in
    //Perform Your Action
})

You can customize the subtitle view for each group item to meet your requirements

Example

In this example, we will create a Custom_Subtitle_Group_Viewa UIView file.

Custom_Subtitle_Group_View

import UIKit
import CometChatSDK
import CometChatUIKitSwift

class CustomSubtitleGroupView: UIView {

    let memberLabel: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.textColor = .systemCyan
        label.font = UIFont.systemFont(ofSize: 15, weight: .bold)
        return label
    }()

    let createdLabel: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.textColor = .init(red: 0.71, green: 0.55, blue: 0.98, alpha: 1.00)
        label.font = UIFont.systemFont(ofSize: 10, weight: .light)
        return label
    }()

    override init(frame: CGRect) {
        super.init(frame: frame)
        addSubview(memberLabel)
        addSubview(createdLabel)

        NSLayoutConstraint.activate([
            memberLabel.topAnchor.constraint(equalTo: topAnchor),
            memberLabel.leadingAnchor.constraint(equalTo: leadingAnchor),
            memberLabel.trailingAnchor.constraint(equalTo: trailingAnchor),

            createdLabel.topAnchor.constraint(equalTo: memberLabel.bottomAnchor, constant: 2),
            createdLabel.leadingAnchor.constraint(equalTo: leadingAnchor),
            createdLabel.trailingAnchor.constraint(equalTo: trailingAnchor),
            createdLabel.bottomAnchor.constraint(equalTo: bottomAnchor)
        ])
    }

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

    func configure(with group: CometChatSDK.Group) {
        memberLabel.text = "Members: \(group.membersCount)"

        let date = Date(timeIntervalSince1970: Double(group.createdAt))
        let dateFormatter = DateFormatter()
        dateFormatter.dateStyle = .medium
        createdLabel.text = "Created: \(dateFormatter.string(from: date))"
    }
}

We will be passing a custom subtitle view to CometChatGroups, ensuring a tailored and user-friendly interface.

Swift

let cometChatGroups = CometChatGroups()
    .setSubtitleView(subtitle: { group in
        let customSubtitleGroupView = CustomSubtitleGroupView()
        customSubtitleGroupView.configure(with: group!)
        return customSubtitleGroupView
})

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

EmptyView report

You can set a custom EmptyView using .set(emptyView: UIView) to match the empty view of your app.

Swift

let cometChatGroups = CometChatGroups()
    .set(emptyView: UIView)

Example In this example, we will create a Custom_Empty_State_GroupViewa UIView file.

import UIKit

class CustomEmptyStateGroupView: UIView {
    // Initialize your subviews
    let imageView: UIImageView = {
        let imageView = UIImageView(image: UIImage(named: "noDataImage"))
        imageView.translatesAutoresizingMaskIntoConstraints = false
        return imageView
    }()

    let messageLabel: UILabel = {
        let label = UILabel()
        label.text = "No groups available"
        label.translatesAutoresizingMaskIntoConstraints = false
        label.font = UIFont.boldSystemFont(ofSize: 16)
        label.textColor = .black
        return label
    }()

    // Override the initializer
    override init(frame: CGRect) {
        super.init(frame: frame)
        // Add subviews and layout constraints
        addSubview(imageView)
        addSubview(messageLabel)
        NSLayoutConstraint.activate([
            imageView.centerXAnchor.constraint(equalTo: centerXAnchor),
            imageView.centerYAnchor.constraint(equalTo: centerYAnchor),
            imageView.heightAnchor.constraint(equalToConstant: 120),
            imageView.widthAnchor.constraint(equalToConstant: 120),

            messageLabel.topAnchor.constraint(equalTo: imageView.bottomAnchor, constant: 8),
            messageLabel.centerXAnchor.constraint(equalTo: centerXAnchor)
        ])
    }

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

We will be passing a custom empty view to CometChatGroups, ensuring a tailored and user-friendly interface.

Swift

let customEmptyStateGroupView = CustomEmptyStateGroupView()
        
let groupsRequestBuilder = GroupsRequest.GroupsRequestBuilder(limit: 1000)

let cometChatGroups = CometChatGroups(groupsRequestBuilder: groupsRequestBuilder)
.set(emptyView: customEmptyStateGroupView)

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

ErrorView

You can set a custom ErrorView using .set(errorView: UIView) to match the error view of your app.

Swift

let cometChatGroups = CometChatGroups()
    .set(errorView: UIView)

Example

In this example, we will create a UIView file Custom_ErrorState_GroupView and pass it inside the .set(errorView: UIView) method.

Custom_ErrorState_GroupView

import UIKit

let CustomErrorStateGroupView: UIView = {
        // Create main view
        let view = UIView()
        view.backgroundColor = .white

        // Create an imageView and add it to the main view
        let imageView = UIImageView(image: UIImage(systemName: "exclamationmark.triangle"))
        imageView.tintColor = .red
        imageView.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(imageView)

        // Create a label with error message and add it to the main view
        let label = UILabel()
        label.text = "An error occurred. Please try again."
        label.font = UIFont.systemFont(ofSize: 16)
        label.textColor = .darkGray
        label.numberOfLines = 0
        label.textAlignment = .center
        label.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(label)

        // Create constraints for imageView and label
        NSLayoutConstraint.activate([
            imageView.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            imageView.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: -50),

            label.topAnchor.constraint(equalTo: imageView.bottomAnchor, constant: 20),
            label.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20),
            label.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -20)
        ])

        return view
    }()

Swift

let customErrorStateGroupView = CustomErrorStateGroupView
let groupsRequestBuilder = GroupsRequest.GroupsRequestBuilder(limit: 1000)

let cometChatGroups = CometChatGroups(groupsRequestBuilder: groupsRequestBuilder)
    .set(errorView: customErrorStateGroupView)

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

Menus

You can set the Custom Menus to add more options to the Groups component.

Swift

let cometChatGroups = CometChatGroups()
    .set(menus: [UIBarButtonItem])

You can customize the menus for groups to meet your requirements

Example

In this example, we’ll craft a custom button tailored for CometChatGroups, enhancing its interface with a personalized menu for a more user-friendly experience.

Swift

let customMenuButton: UIBarButtonItem = {
let button = UIButton(type: .system)
    button.setImage(UIImage(systemName: "swift"), for: .normal)
    button.setTitle("CometChat", for: .normal)
    button.addTarget(self, action: #selector(handleCustomMenu), for: .touchUpInside)
