## Usage

### Integration

`CometChatGroupMembers`, 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 group 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 GroupMembers component into your application.

<Tabs>
  <Tab title="Swift">
    ```swift theme={null}
    let group =  Group(guid: <#T##String#>, name: <#T##String#>, groupType: <#T##CometChat.groupType#>, password: <#T##String?#>)
    let cometChatGroupMembers = CometChatGroupMembers(group: group)
    let naviVC = UINavigationController(rootViewController: cometChatGroupMembers)
    self.present(naviVC, animated: true)
    ```
  </Tab>
</Tabs>

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

    })
    ```
  </Tab>
</Tabs>

### 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](/sdk/ios/retrieve-groups) 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](/sdk/ios/retrieve-groups)

| 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.                          |
| **scopes**           | \[String] | used for fetching group members based on multiple scopes                                                            |

**Example**

In the example below, we are applying a filter to the Group List based on limit and scope.

<Tabs>
  <Tab title="Swift">
    ```swift theme={null}
    let group =  Group(guid: "mrc-uid", name: "", groupType: .public, password: .none)
    let groupMembersRequestBuilder =  GroupMembersRequest.GroupMembersRequestBuilder(guid: group.guid).set(limit: 2).set(scopes: ["admin"])

    let cometChatGroupMembers = CometChatGroupMembers(group: group, groupMembersRequestBuilder: groupMembersRequestBuilder)

    let naviVC = UINavigationController(rootViewController: cometChatGroupMembers)
    self.present(naviVC, animated: true)
    ```
  </Tab>
</Tabs>

##### 2. SearchRequestBuilder

The SearchRequestBuilder uses [GroupsRequestBuilder](/sdk/ios/retrieve-groups) 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**

<Tabs>
  <Tab title="Swift">
    ```swift theme={null}
    let group =  Group(guid: "mrc-uid", name: "", groupType: .public, password: .none)
    let groupMembersRequestBuilder =  GroupMembersRequest.GroupMembersRequestBuilder(guid: group.guid)
        .set(searchKeyword: "")

    let cometChatGroupMembers = CometChatGroupMembers(group: group, groupMembersRequestBuilder: groupMembersRequestBuilder)

    let naviVC = UINavigationController(rootViewController: cometChatGroupMembers)
    self.present(naviVC, animated: true)
    ```
  </Tab>
</Tabs>

### 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 own views, layouts, and UI elements and then incorporate those into the component.

The `Join Group` component does not provide additional functionalities beyond this level of customization.

#### ListItemView

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

#### 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.

<Tabs>
  <Tab title="Swift">
    ```swift theme={null}
    let cometChatGroupMembers = CometChatGroupMembers(group: group)
        .setSubtitleView (subtitleView:{ groupMember in

                                                  title: "Delete",
                                                  icon: UIImage(systemName: "trash.square"),
                                                  backgroundColor: .red,
                                                  onClick: { groupMember, group, section, option, controller in
                                                            print("Custom option clicked!")
    })

    let cometChatGroupMembers = CometChatGroupMembers(group: group)
    .setOptions(options: { group, groupMember in
    return [customOption]
    })
    ```
  </Tab>
</Tabs>

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