Jitsi Meet UI Not Rendering After Accepting VoIP Call From Lock Screen In IOS

by ADMIN 78 views

Introduction

Integrating VoIP call functionality with Jitsi Meet is a complex task that requires careful consideration of various factors. While the functionality works perfectly when the app is in the foreground or background, there are instances where the Jitsi Meet UI fails to render properly. This article focuses on a specific issue where the Jitsi Meet UI is not rendering after accepting a VoIP call from the lock screen in iOS.

Problem Description

When a VoIP notification is received, and the user accepts the call, they are directly joined into the Jitsi meeting. However, if the device is locked and the user accepts the call from the lock screen, they successfully join the meeting, and the host can see them as a participant. But when the user unlocks the device, a black screen appears instead of displaying the Jitsi Meet view with all its access control options.

Code Implementation

The provided code snippet demonstrates the integration of VoIP call functionality with Jitsi Meet using iOS Swift. The code creates a JitsiMeetController instance and sets it as the root view controller when the user accepts the call.

// Received VoIP Notification with Payload that contains Jitsi Meet room ID
// Show call notification
// Upon Accept call
let jitsiMeetController = JitsiMeetController()
UIApplication.shared.setRootController(for: jitsiMeetController)

//Setting the Root View Controller
func setRootController(for rootController: UIViewController) {
    guard let window = getSceneDelegateWindow() else { return }
    window.rootViewController = rootController
    window.makeKeyAndVisible()
}

//Jitsi Meet Controller Implementation
class JitsiMeetController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        // Create and configure JitsiMeet view
        var jitsiMeetView = JitsiMeetView()
        let options = JitsiMeetConferenceOptions.fromBuilder { builder in
            builder.serverURL = URL(string: "serverURL")
            builder.room = "roomId"
            builder.token = "JWTToken"
            builder.userInfo = JitsiMeetUserInfo(displayName: "displayName",
                                                 andEmail: "email",
                                                 andAvatar: nil)
            builder.setVideoMuted(true)
            builder.setAudioMuted(true)
        }
        jitsiMeetView?.join(options) // Join Jitsi Meeting
    }
}
