Push Notifications

The Channelize.io iOS SDK allows your users to receive important messages when the app is running in the background or a device is idle. You can also build your own Push Notifications system using Channelize.io webhooks.

Do the following steps to setup push notifications:

Step 1: Create a firebase account and use its messaging framework. Add the following pods.

pod 'Firebase/Messaging'
pod 'Firebase/Core'

Step 2: In AppDelegate.swift file in didFinishLaunchingWithOptions functions call this.

FirebaseApp.configure()
Messaging.messaging().delegate = self

Step 3: Write MessagingDelegate functions and update fcmToken using Channelize.updateToken(token: fcmToken).

extension AppDelegate : MessagingDelegate {
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        print("FCM Token -> \(fcmToken)")
        Channelize.updateFcmToken(token: fcmToken, completion: {(status,errorString) in
            if status {
                print("FCM Token Registered Successfullt")
            } else {
                print("Failed to Register FCM Token with errorString\(errorString ?? "")")
            }
        })
    }
    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
        print("Message Recieved \(remoteMessage.appData)")
    }
}

Step 4: Differentiate your main app push notifications (if Channelize.io real-time messaging is used as an integration) and Channelize.io notifications as shown below.

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
    if userInfo["isMessenger"] != nil{
        openPrimeMessenger(contentInfo: userInfo)
    }else{
        // Handle yours app notifications
    }
}


func openPrimeMessenger(contentInfo: [AnyHashable : Any]) {
    if let navigationController = UIApplication.shared.keyWindow?.rootViewController as? UINavigationController{
        ChUI.launchChannelize(navigationController: navigationController, data: contentInfo)
    }
}
           

Register/Update FCM Token

To register and update the FCM token make the below API call.

Channelize.updateFcmToken(token: fcmToken, completion: {(status,errorString) in
    if status {
        print("FCM Token Registered Successfullt")
    } else {
        print("Failed to Register FCM Token with errorString\(errorString ?? "")")
    }
 })

Delete FCM Token

To delete the FCM token for a user make the below API call.

Channelize.deleteToken()
