# Transfer Ownership
> Transfer Ownership — CometChat documentation.
## Overview
`CometChatTransferOwnership` is a [Component](/ui-kit/ios/v4/components-overview#components) that allows the current owner or administrator of a group to transfer the ownership rights and administrative control of that group to another user. By transferring ownership, the original owner can designate a new user as the group owner, giving them full control and administrative privileges over the group.
Here are some key points regarding the transfer ownership feature in CometChat:
1. **Administrative Control**: The current owner or administrator of the group has the authority to initiate the transfer of ownership. This feature is typically available to ensure flexibility and allow smooth transitions of group ownership.
2. **New Group Owner**: During the transfer process, the current owner can select a specific user from the group members to become the new owner. This new owner will then assume the responsibilities and privileges associated with being the group owner.
3. **Administrative Privileges**: As the new owner, the designated user will gain full administrative control over the group. They will have the ability to manage group settings, add or remove members, moderate conversations, and perform other administrative actions.
4. **Group Continuity**: Transferring ownership does not disrupt the existing group or its content. The transfer ensures the continuity of the group while transferring the administrative control to a new owner.
The Transfer Ownership component is composed of the following BaseComponents:
| Components | Description |
| ----------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [CometchatGroupMembers](/ui-kit/ios/v4/group-members) | `CometChatGroupMembers` is an independent component designed to create a user-friendly screen for browsing and managing group members. Users can effortlessly search for specific members and take actions such as kicking, banning, or changing member scopes directly from the interface. |
| [CometChatListItem](/ui-kit/ios/v4/list-item) | This component renders information extracted from a `User` object onto a tile, featuring a title, subtitle, leading view, and trailing view. |
***
## Usage
### Integration
`CometChatTransferOwnership`, as a custom **view controller**, offers flexible integration options, allowing it to be launched directly via button clicks or any user-triggered action. Additionally, it seamlessly integrates into tab view controllers. With banned members, users gain access to a wide range of parameters and methods for effortless customization of its user interface.
The following code snippet exemplifies how you can seamlessly integrate the TransferOwnership component into your application.
```swift theme={null}
let group = Group(guid: "your UID", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
let naviVC = UINavigationController(rootViewController: cometChatTransferOwnership)
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](/ui-kit/ios/v4/components-overview#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. SetOnTransferOwnership
The `setOnTransferOwnership` action is activated when you select a group member and click on the transfer ownership submit button. you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.
```swift theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setOnTransferOwnership { group, groupMember in
//Perform Your Action
}
```
##### 2. SetOnItemClick
This method proves valuable when users seek to override onItemClick functionality within CometChatTransferOwnership, 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 theme={null}
let group = Group(guid: "your UID", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setOnItemClick { groupMember, indexPath in
//Perform Your Action
}
```
##### 3. SetOnItemLongClick
This method becomes invaluable when users seek to override long-click functionality within CometChatTransferOwnership, 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 theme={null}
let group = Group(guid: "your UID", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setOnItemLongClick { groupMember, indexPath in
//Perform Your Action
}
```
##### 4. SetOnError
You can customize this behavior by using the provided code snippet to override the `On Error` and improve error handling.
```swift theme={null}
let group = Group(guid: "your UID", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setOnError { error in
//Perform Your Action
}
```
##### 5. 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 theme={null}
let group = Group(guid: "your UID", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setOnBack {
//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. GroupMembersRequestBuilder
The [GroupMembersRequestBuilder](/sdk/ios/retrieve-group-members) enables you to filter and customize the group members list based on available parameters in GroupMembersRequestBuilder. This feature allows you to create more specific and targeted queries when fetching groups. The following are the parameters available in [GroupMembersRequestBuilder](/sdk/ios/retrieve-group-members)
| Methods | Type | Description |
| -------------------- | --------- | -------------------------------------------------------------------------------------------------- |
| **setLimit** | Int | sets the number of banned members that can be fetched in a single request, suitable for pagination |
| **setSearchKeyword** | String | used for fetching banned members matching the passed string |
| **setScope** | \[String] | used for fetching group members based on multiple scopes |
**Example**
In the example below, we are applying a filter to the Group Members by setting the limit to 1 and setting the scope to show only admin.
```swift theme={null}
let group = Group(guid: "Your-uid", name: "", groupType: .public, password: .none)
let groupMembersRequestBuilder = GroupMembersRequest.GroupMembersRequestBuilder(guid: group.guid).set(scopes: ["admin"]).set(limit: 1)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group, groupMembersRequestBuilder: groupMembersRequestBuilder)
let naviVC = UINavigationController(rootViewController: cometChatTransferOwnership)
self.present(naviVC, animated: true)
```
##### 2. SearchRequestBuilder
The SearchRequestBuilder uses [GroupMembersRequestBuilder](/sdk/ios/retrieve-group-members) enables you to filter and customize the search list based on available parameters in GroupMembersRequestBuilder. This feature allows you to keep uniformity between the displayed Group Members List and searched Group Members List.
**Example**
```swift theme={null}
let group = Group(guid: "Your-uid", name: "", groupType: .public, password: .none)
let groupMembersRequestBuilder = GroupMembersRequest.GroupMembersRequestBuilder(guid: group.guid).set(scopes: ["admin"]).set(limit: 2).set(searchKeyword: "")
let cometChatTransferOwnership = CometChatTransferOwnership(group: group, groupMembersRequestBuilder: groupMembersRequestBuilder)
let naviVC = UINavigationController(rootViewController: cometChatTransferOwnership)
self.present(naviVC, animated: true)
```
***
### Events
[Events](/ui-kit/ios/v4/components-overview#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.
Events emitted by the Join Group component is as follows.
| Event | Description |
| --------------------- | --------------------------------------------------------------------- |
| **onOwnershipChange** | Triggers when the ownership of a group member is changed successfully |
```swift theme={null}
// View controller from your project where you want to listen events.
public class ViewController: UIViewController {
public override func viewDidLoad() {
super.viewDidLoad()
// Subscribing for the listener to listen events from user module
CometChatGroupEvents.addListener("UNIQUE_ID", self as CometChatGroupEventListener)
}
}
// Listener events from groups module
extension ViewController: CometChatGroupEventListener {
public func onOwnershipChange(group: Group?, member: GroupMember?) {
// Do Stuff
}
}
```
```swift Emitting Group Events theme={null}
///emit this when ownership is changed by logged in user.
CometChatGroupEvents.emitOnGroupMemberChangeScope(updatedBy: User , updatedUser: User , scopeChangedTo: CometChat.MemberScope , scopeChangedFrom: CometChat.MemberScope, group: Group)
```
***
```swift View controller theme={null}
public override func viewWillDisappear(_ animated: Bool) {
// Uncubscribing for the listener to listen events from user module
CometChatGroupEvents.removeListener("LISTENER_ID_USED_FOR_ADDING_THIS_LISTENER")
}
```

### Advance
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 TransferOwnership Component, allowing for enhanced customization and flexibility in its rendering.
```swift theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setListItemView { groupMember in
//Perform Your Action
}
```
**Example**
In this example, we will create a UIView file `CustomListItemGroupView` and pass it inside the `setListItemView()` method.
```swift CustomListItemGroupView theme={null}
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 = .systemRed
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")
}
func configure(with user: User) {
titleLabel.text = user.name
if let avatarUrl = user.avatar {
groupImageView.setAvatar(avatarUrl: avatarUrl, with: user.name ?? "")
} else {
// handle when avatar is nil
}
}
}
```
```swift theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setListItemView { user in
let customListItemGroupView = CustomListItemGroupView()
customListItemGroupView.configure(with: user!)
return customListItemGroupView
}
```
Ensure to pass and present `CometChatTransferOwnership`. 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 theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setSubtitleView { groupMember in
//Perform Your Action
}
```
* You can customize the subtitle view for each TransferOwnership item to meet your requirements
**Example**
In this example, we will create a `Custom_Subtitle_GroupMember_View`a UIView file.
```swift Custom_Subtitle_GroupMember_View theme={null}
import UIKit
import CometChatSDK
import CometChatUIKitSwift
class CustomSubtitleGroupMemberView: UIView {
let memberNameLabel: UILabel = {
let label = UILabel()
label.translatesAutoresizingMaskIntoConstraints = false
label.textColor = .init(red: 0.42, green: 0.01, blue: 0.84, alpha: 1.00)
label.font = UIFont.systemFont(ofSize: 10, weight: .medium)
return label
}()
let joinedAtLabel: UILabel = {
let label = UILabel()
label.translatesAutoresizingMaskIntoConstraints = false
label.textColor = .systemBrown
label.font = UIFont.systemFont(ofSize: 10, weight: .medium)
return label
}()
override init(frame: CGRect) {
super.init(frame: frame)
addSubview(memberNameLabel)
addSubview(joinedAtLabel)
NSLayoutConstraint.activate([
memberNameLabel.topAnchor.constraint(equalTo: topAnchor),
memberNameLabel.leadingAnchor.constraint(equalTo: leadingAnchor),
memberNameLabel.trailingAnchor.constraint(equalTo: trailingAnchor),
joinedAtLabel.topAnchor.constraint(equalTo: memberNameLabel.bottomAnchor, constant: 2),
joinedAtLabel.leadingAnchor.constraint(equalTo: leadingAnchor),
joinedAtLabel.trailingAnchor.constraint(equalTo: trailingAnchor),
joinedAtLabel.bottomAnchor.constraint(equalTo: bottomAnchor)
])
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func configure(with user: User) {
memberNameLabel.text = "Member: \(user.name ?? "")"
}
}
```
We will be passing a custom subtitle view to CometChatTransferOwnership, ensuring a tailored and user-friendly interface.
```swift theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setSubtitleView { user in
let customSubtitleGroupMemberView = CustomSubtitleGroupMemberView()
customSubtitleGroupMemberView.configure(with: user!)
return customSubtitleGroupMemberView
}
```
Ensure to pass and present `CometChatTransferOwnership`. 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 theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.set(emptyView: UIView)
```
**Example**
In this example, we will create a `Custom_Empty_State_GroupView`a UIView file.
```swift theme={null}
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 CometChatTransferOwnership, ensuring a tailored and user-friendly interface.
```swift theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let groupMembersRequestBuilder = GroupMembersRequest.GroupMembersRequestBuilder(guid: group.guid).set(limit: 1000)
let customEmptyStateGroupView = CustomEmptyStateGroupView()
let cometChatTransferOwnership = CometChatTransferOwnership(group: group, groupMembersRequestBuilder: groupMembersRequestBuilder)
.set(emptyView: customEmptyStateGroupView)
```
Ensure to pass and present `CometChatTransferOwnership`. 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 theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.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.
```swift Custom_ErrorState_GroupView theme={null}
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 theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let groupMembersRequestBuilder = GroupMembersRequest.GroupMembersRequestBuilder(guid: group.guid).set(limit: 1000)
let customErrorStateGroupView = CustomErrorStateGroupView
let cometChatTransferOwnership = CometChatTransferOwnership(group: group, groupMembersRequestBuilder: groupMembersRequestBuilder)
.set(errorView: customErrorStateGroupView)
```
Ensure to pass and present `CometChatTransferOwnership`. 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 TransferOwnership component.
```swift theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.set(menus: [UIBarButtonItem])
```
* You can customize the menus for TransferOwnership to meet your requirements
**Example**
In this example, we'll craft a custom button tailored for `CometChatTransferOwnership`, enhancing its interface with a personalized `menu` for a more user-friendly experience.
```swift theme={null}
let customMenuButton: UIBarButtonItem = {
let button = UIButton(type: .system)
button.setImage(UIImage(systemName: "swift"), for: .normal)
button.setTitle("", for: .normal)
button.addTarget(self, action: #selector(handleCustomMenu), for: .touchUpInside)
let barButtonItem = UIBarButtonItem(customView: button)
return barButtonItem
}()
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.set(menus: [customMenuButton])
```
Ensure to pass and present `CometChatTransferOwnership`. If a navigation controller is already in use, utilize the pushViewController function instead of directly presenting the view controller.
***
#### Options
Enhance your TransferOwnership component by setting Custom Options to incorporate additional functionalities when swiping
```swift theme={null}
let group = Group(guid: "your-uid", name: "", groupType: .public, password: .none)
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setOptions { group, groupMember in
//Perform Your Action
}
```
* You can customize the options for TransferOwnership to meet your requirements
**Example**
In this example, we've enhanced the interface of `CometChatTransferOwnership` by introducing a tailored feature. By adding a custom option, such as "Delete" with a corresponding trash icon, users can now enjoy a more interactive and user-friendly experience.
```swift theme={null}
let customOption = CometChatGroupMemberOption(id: "custom_option_1",
title: "Delete",
icon: UIImage(systemName: "trash.square"),
backgroundColor: .red,
onClick: { groupMember, group, section, option, controller in
print("Custom option clicked!")
})
let cometChatTransferOwnership = CometChatTransferOwnership(group: group)
.setOptions { group, groupMember in
return [customOption]
}
```
Ensure to pass and present `CometChatTransferOwnership`. If a navigation controller is already in use, utilize the pushViewController function instead of directly presenting the view controller.
Ensure to include your GUID and the name of your group when configuring group settings.
