Use in conjunction with Call Kit

This doc will introduce how to use In-app Chat Kit with Call Kit.

Prerequisites

Integrate the In-app Chat Kit SDK into your project. For more information, see Quick start.

Integrate the Call Kit

Add Call Kit dependency

• Add the following dependency to your Podfile file:

pod 'ZegoUIKitPrebuiltCall'

• Open the terminal and navigate to the root directory of your project. Run the following command:

pod install

Initialize Call Kit

After successfully logging in to the In-app Chat Kit, add the following code to initialize Call Kit:

let appID: UInt32 = YOUR_APPID
let appSign: String = YOUR_APP_SIGN
let userID: String = YOUR_USER_ID
let userName: String = YOUR_USER_NAME
ZIMKit.connectUser(userID: userID, userName: userName) { error in
    if error.code == .success {
        let config = ZegoUIKitPrebuiltCallInvitationConfig(notifyWhenAppRunningInBackgroundOrQuit: true, isSandboxEnvironment: false)
        ZegoUIKitPrebuiltCallInvitationService.shared.initWithAppID(appID, appSign: appSign, userID: userID, userName: userName, config: config)
    }
}

Set ZIMKitMessagesListVCDelegate delegate

• If you are integrating through ZIMKitConversationListVC, you can set it using the following code:

let conversationVC = ZIMKitConversationListVC()
conversationVC.messageDelegate = self

• If you are integrating through ZIMKitMessagesListVC, you can set it using the following code:

let messageVC = ZIMKitMessagesListVC(conversationID: "conversationID", type: .peer)
messageVC.delegate = self

Add a call button

Implement the getMessageListHeaderBar delegate and add the call button.

import ZIMKit
import ZegoUIKitPrebuiltCall

extension ViewController: ZIMKitMessagesListVCDelegate {

    func getMessageListHeaderBar(_ messageListVC: ZIMKitMessagesListVC) -> ZIMKitHeaderBar? {

        if messageListVC.conversationType != .peer { return nil }

        // Get conversationID and conversationName from messageListVC
        let conversationID = messageListVC.conversationID
        let conversationName = messageListVC.conversationName

        // Create voice call button and set the user to be called as ZegoUIKitUser
        let voiceCallButton = ZegoSendCallInvitationButton(ZegoInvitationType.voiceCall.rawValue)
        voiceCallButton.inviteeList = [ZegoUIKitUser(conversationID, conversationName)]

        // Create video call button and set the user to be called as ZegoUIKitUser
        let videoCallButton = ZegoSendCallInvitationButton(ZegoInvitationType.videoCall.rawValue)
        videoCallButton.inviteeList = [ZegoUIKitUser(conversationID, conversationName)]

        // Create UIBarButtonItem using the above buttons
        let voiceItem = UIBarButtonItem(customView: voiceCallButton)
        let videoItem = UIBarButtonItem(customView: videoCallButton)

        // Create HeaderBar and set voice and video to `rightItems`
        let header = ZIMKitHeaderBar()
        header.rightItems = [videoItem, voiceItem]

        return header
    }
}

So far, you have successfully integrated Call Kit in the In-app Chat Kit. You can now run and experience it.
