Push Notification

Push Notification Setup

Add import statement in AppDelegate file to access the methods

import Kommunicate

a) Send device token to Kommunicate server:

In your AppDelegate’s didRegisterForRemoteNotificationsWithDeviceToken method send device registration to Kommunicate server after you get deviceToken from APNS. Sample code is as below:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{

    print("DEVICE_TOKEN_DATA :: \(deviceToken.description)")  // (SWIFT = 3) : TOKEN PARSING

    var deviceTokenString: String = ""
    for i in 0..<deviceToken.count
    {
        deviceTokenString += String(format: "%02.2hhx", deviceToken[i] as CVarArg)
    }
    print("DEVICE_TOKEN_STRING :: \(deviceTokenString)")

    if (KMUserDefaultHandler.getApnDeviceToken() != deviceTokenString)
    {
        let kmRegisterUserClientService: KMRegisterUserClientService = KMRegisterUserClientService()
        kmRegisterUserClientService.updateApnDeviceToken(withCompletion: deviceTokenString, withCompletion: { (response, error) in
            print ("REGISTRATION_RESPONSE :: \(String(describing: response))")
        })
    }
}

b) Receiving push notification:

Once your app receives notification, pass it to Kommunicate handler for chat notification processing.

func registerForNotification() {
    UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
        if granted {
            DispatchQueue.main.async {
                UIApplication.shared.registerForRemoteNotifications()
            }
        }
    }
}

/// Add below lines inside didFinishLaunchingWithOptions method.

    UNUserNotificationCenter.current().delegate = self
    registerForNotification()

    KMPushNotificationHandler.shared.dataConnectionNotificationHandlerWith(Kommunicate.defaultConfiguration, Kommunicate.kmConversationViewConfiguration)
    let kmApplocalNotificationHandler: KMAppLocalNotification =  KMAppLocalNotification.appLocalNotificationHandler()
    kmApplocalNotificationHandler.dataConnectionNotificationHandler()

c) Handling app launch on notification click:

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    let service = KMPushNotificationService()
    let dict = notification.request.content.userInfo
    guard !service.isKommunicateNotification(dict) else {
        service.processPushNotification(dict, appState: UIApplication.shared.applicationState)
        completionHandler([])
        return
    }
    completionHandler([.sound, .badge, .alert])
}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    let service = KMPushNotificationService()
    let dict = response.notification.request.content.userInfo
    if service.isApplozicNotification(dict) {
        service.processPushNotification(dict, appState: UIApplication.shared.applicationState)
    }
    completionHandler()
}

d) AppDelegate changes for foreground notification:

func applicationWillEnterForeground(_ application: UIApplication) {
    print("APP_ENTER_IN_FOREGROUND")
    UIApplication.shared.applicationIconBadgeNumber = 0
}

e) Save Context when app terminates:

 func applicationWillTerminate(application: UIApplication) {
     KMDBHandler.sharedInstance().saveContext()
 }

You can check the sample AppDelegate file here.

Certificates

a) Upload development and distribution APNs certificates

Upload development and distribution APNs certificates on Kommunicate dashboard, this will allow Kommunicate to send the notification for new messages to your mobile app.

b) Updating Capabilities

Post setting up APNs, the next step is to enable push notifications within your project.
To do that click on your project and select your project from TARGETS

• Next select signing & capabilities section and click + to add below capabilities
  

1. Push Notifications capability
   
2. Background Modes
   • Select Background Fetch and Remote notifications
