Call invitation config

Customize the call ringtone

Ringtone for call invitation

If you want to set the call ringtone for receiving incoming call invitations or sending outgoing call invitations, you can use the incomingCallRingtone and outgoingCallRingtone config in the ZegoUIKitPrebuiltCallInvitationService.

Here is the reference code:

With call invitation

class CallInvitationVC: UIViewController {
    let appID: UInt32 = yourAppID
    let appSign: String = "yourAppSign"
    let userID: String = "userID"
    let userName: String = "userName"
    let voiceCallButton: ZegoSendCallInvitationButton = ZegoSendCallInvitationButton(ZegoInvitationType.voiceCall.rawValue)
    let videoCallButton: ZegoSendCallInvitationButton = ZegoSendCallInvitationButton(ZegoInvitationType.videoCall.rawValue)

    override func viewDidLoad() {
        super.viewDidLoad()
        let config = ZegoUIKitPrebuiltCallInvitationConfig([ZegoUIKitSignalingPlugin()], notifyWhenAppRunningInBackgroundOrQuit: false, isSandboxEnvironment: false)
        config.incomingCallRingtone = NSBundle.mainBundle().pathForResource("incomingCallRingtone", ofType: "mp3")
        config.outgoingCallRingtone = NSBundle.mainBundle().pathForResource("outgoingCallRingtone", ofType: "mp3")
        ZegoUIKitPrebuiltCallInvitationService.shared.initWithAppID(self.appID, appSign: self.appSign, userID: self.userID, userName: self.userName, config: config)
        ZegoUIKitPrebuiltCallInvitationService.shared.delegate = self
    }
}

extension CallInvitationVC: ZegoUIKitPrebuiltCallInvitationServiceDelegate {
    //MARK: -ZegoUIKitPrebuiltCallInvitationServiceDelegate
    func requireConfig(_ data: ZegoCallInvitationData) -> ZegoUIKitPrebuiltCallConfig {
        var config = ZegoUIKitPrebuiltCallConfig.groupVoiceCall()
        if data.type == .voiceCall {
            if data.invitees?.count ?? 0 > 1 {
                config = ZegoUIKitPrebuiltCallConfig.groupVoiceCall()
            } else {
                config = ZegoUIKitPrebuiltCallConfig.oneOnOneVoiceCall()
            }
        } else {
            if data.invitees?.count ?? 0 > 1 {
                config = ZegoUIKitPrebuiltCallConfig.groupVideoCall()
            } else {
                config = ZegoUIKitPrebuiltCallConfig.oneOnOneVideoCall()
            }
        }
        return config
    }

Ringtone for offline call invitation

To specify a ringtone for offline call invitations:

Follow the steps in Quick start to enable and complete the congirations.
Go to ZEGOCLOUD Admin Console to configure a Push Resource ID.
Replace the resourceID parameter in the ZegoSendCallInvitationButton method with the Push Resource ID you get.

After the completion, the ringtone corresponding to the ID you set will be played when others receive offline call invitations.

Here is the reference code:

With call invitation


let callTargetUser: ZegoUIkitUser = ZegoUIkitUser.init("TargetUserID", "TargetUserName")
let sendVideoCallButton: ZegoSendCallInvitationButton = ZegoSendCallInvitationButton(ZegoInvitationType.videoCall.rawValue)
sendVideoCallButton.inviteeList.append(callTargetUser)
sendVideoCallButton.resourceID = "zegouikit_call" // For offline call notification

Hide the decline button

To hide the Decline button when receiving incoming call invitations, set the showDeclineButton to false.

With call invitation

class CallInvitationVC: UIViewController {
    let appID: UInt32 = yourAppID
    let appSign: String = "yourAppSign"
    let userID: String = "userID"
    let userName: String = "userName"
    let voiceCallButton: ZegoSendCallInvitationButton = ZegoSendCallInvitationButton(ZegoInvitationType.voiceCall.rawValue)
    let videoCallButton: ZegoSendCallInvitationButton = ZegoSendCallInvitationButton(ZegoInvitationType.videoCall.rawValue)

    override func viewDidLoad() {
        super.viewDidLoad()
        let config = ZegoUIKitPrebuiltCallInvitationConfig([ZegoUIKitSignalingPlugin()], notifyWhenAppRunningInBackgroundOrQuit: true, isSandboxEnvironment: false)
        config.showDeclineButton = false
        ZegoUIKitPrebuiltCallInvitationService.shared.initWithAppID(self.appID, appSign: self.appSign, userID: self.userID, userName: self.userName, config: config)
        ZegoUIKitPrebuiltCallInvitationService.shared.delegate = self
    }
}

extension CallInvitationVC: ZegoUIKitPrebuiltCallInvitationServiceDelegate {
    //MARK: -ZegoUIKitPrebuiltCallInvitationServiceDelegate
 func requireConfig(_ data: ZegoCallInvitationData) -> ZegoUIKitPrebuiltCallConfig {
    
    if data.type == .voiceCall {
        if data.invitees?.count ?? 0 > 1 {
            let config = ZegoUIKitPrebuiltCallConfig.groupVoiceCall()
            return config
        } else {
            let config = ZegoUIKitPrebuiltCallConfig.oneOnOneVoiceCall()
            return config
        }
    } else {
        if data.invitees?.count ?? 0 > 1 {
            let config = ZegoUIKitPrebuiltCallConfig.groupVideoCall()
            return config
        } else {
            let config = ZegoUIKitPrebuiltCallConfig.oneOnOneVideoCall()
            return config
        }
    }
  }

Modify User Interface text

Call Kit (ZegoUIKitPrebuiltCallWithInvitation)'s UI text provided by the internal components is editable, to modify those, use the innerText config.

Here is the reference code:

With call invitation

class CallInvitationVC: UIViewController {
    let appID: UInt32 = yourAppID
    let appSign: String = "yourAppSign"
    let userID: String = "userID"
    let userName: String = "userName"
    let voiceCallButton: ZegoSendCallInvitationButton = ZegoSendCallInvitationButton(ZegoInvitationType.voiceCall.rawValue)
    let videoCallButton: ZegoSendCallInvitationButton = ZegoSendCallInvitationButton(ZegoInvitationType.videoCall.rawValue)

    override func viewDidLoad() {
        super.viewDidLoad()
        let config = ZegoUIKitPrebuiltCallInvitationConfig([ZegoUIKitSignalingPlugin()], notifyWhenAppRunningInBackgroundOrQuit: true, isSandboxEnvironment: false)
        config.innerText.incomingCallPageAcceptButton = "Accept"
        config.innerText.incomingCallPageDeclineButton = "Decline"
        ZegoUIKitPrebuiltCallInvitationService.shared.initWithAppID(self.appID, appSign: self.appSign, userID: self.userID, userName: self.userName, config: config)
        ZegoUIKitPrebuiltCallInvitationService.shared.delegate = self
    }
}

extension CallInvitationVC: ZegoUIKitPrebuiltCallInvitationServiceDelegate {
    //MARK: -ZegoUIKitPrebuiltCallInvitationServiceDelegate
 func requireConfig(_ data: ZegoCallInvitationData) -> ZegoUIKitPrebuiltCallConfig {
    
    if data.type == .voiceCall {
        if data.invitees?.count ?? 0 > 1 {
            let config = ZegoUIKitPrebuiltCallConfig.groupVoiceCall()
            return config
        } else {
            let config = ZegoUIKitPrebuiltCallConfig.oneOnOneVoiceCall()
            return config
        }
    } else {
        if data.invitees?.count ?? 0 > 1 {
            let config = ZegoUIKitPrebuiltCallConfig.groupVideoCall()
            return config
        } else {
            let config = ZegoUIKitPrebuiltCallConfig.oneOnOneVideoCall()
            return config
        }
    }

Listen for call invitation event callbacks

You can implement further business logic by listening for event callbacks related to the call invitation.

The following are supported event callbacks:

func onIncomingCallDeclineButtonPressed(): This callback will be triggered when the Decline button is pressed (the callee declines the call invitation).
func onIncomingCallAcceptButtonPressed(): This callback will be triggered when the Accept button is pressed (the callee accepts the call invitation).
func onIncomingCallReceived(_ callID: String, caller: ZegoCallUser, callType: ZegoCallType, callees: [ZegoCallUser]?): This callback will be triggered when receiving call invitations.
func onIncomingCallCanceled(_ callID: String, caller: ZegoCallUser): This callback will be triggered when the caller cancels the call invitation.
func onIncomingCallTimeout(_ callID: String, caller: ZegoCallUser): The callee will receive a notification through this callback when the callee doesn't respond to the call invitation after a timeout duration.
func onOutgoingCallCancelButtonPressed(): This callback will be triggered when the Cancel button is pressed (the caller cancels the call invitation).
func onOutgoingCallAccepted(_ callID: String, callee: ZegoCallUser): The caller will receive a notification through this callback when the callee accepts the call invitation.
func onOutgoingCallRejectedCauseBusy(_ callID: String, callee: ZegoCallUser): The caller will receive a notification through this callback when the callee rejects the call invitation (the callee is busy).
func onOutgoingCallDeclined(_ callID: String, callee: ZegoCallUser): The caller will receive a notification through this callback when the callee declines the call invitation actively.
func onOutgoingCallTimeout(_ callID: String, callees: [ZegoCallUser]): The caller will receive a notification through this callback when the call invitation didn't get responses after a timeout duration.
func requireRoomForegroundView() -> UIView?: Add a view on the top layer of the audio and video call interface. The size of the view is determined by the view.frame passed by you. For example, as shown in the following image, the foreground view can set to red (or other colors) and covering the entire interface.
