BPMobileMessaging

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

Quick Start

Adding the SDK to your project

BPMobileMessaging is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'BPMobileMessaging'

Add the following line into your project's AppDelegate.swift file:

import BPMobileMessaging

Generate the unique clientID string value. The clientID should be generated when application runs for the first time on the mobile device and saved in the local storage. The application should use the same value until it is deleted from the device. The clientID should be unique for each application / device combination.

var clientID = UUID().uuidString

Create instance of the ContactCenterCommunicator class which would handle communications with the BPCC server:

let baseURL = URL(string: "https://<your server URL>")!
let tenantURL = URL(string: "<your tenant URL>")!
var appID = "<your messaging scenario entry ID>"

lazy var contactCenterService: ContactCenterCommunicating = {
    ContactCenterCommunicator(baseURL: baseURL, tenantURL: tenantURL, appID: appID, clientID: clientID)
}()

Register for push notifications. The SDK supports both native APNs and Google Firebase push notifications frameworks. Only one framework should be used at time. Define a variable to store the device token:

var deviceToken: String?

If using APNs, implement the function to handle the APNs device token result:

func application(_ application: UIApplication,
            didRegisterForRemoteNotificationsWithDeviceToken
                deviceToken: Data) {
    self.deviceToken = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
    service?.deviceTokenChanged(to: deviceToken)
}

If using Google Firebase, implement MessagingDelegate extension:

extension AppDelegate: MessagingDelegate {
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {
        guard let fcmToken = fcmToken else {
            print("Empty fcm token")
            return
        }
        print("Received fcm token from Firebase: \(fcmToken)")
        self.deviceToken = fcmToken
    }
}

Implement UNUserNotificationCenterDelegate extension to handle push notifications:

extension AppDelegate : UNUserNotificationCenterDelegate {

  func userNotificationCenter(_ center: UNUserNotificationCenter,
                              didReceive response: UNNotificationResponse,
                              withCompletionHandler completionHandler: @escaping () -> Void) {
    let userInfo = response.notification.request.content.userInfo
    contactCenterService.appDidReceiveMessage(userInfo)
    completionHandler()
  }
}

Set the delegates for APNs and Google Firebase frameworks:

UNUserNotificationCenter.current().delegate = self
Messaging.messaging().delegate = self

Request permissions to receive push notifications:

let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(options: authOptions) { (authorized, error) in
    guard authorized else {
        if let error = error {
            print("Failed to authorize remote notifications: \(error)")
        }
        return
    }
    DispatchQueue.main.async {
        UIApplication.shared.registerForRemoteNotifications()
    }
    print("Successfully authorized for remote notifications")
}

Implement ContactCenterEventsDelegating extension to receive the chat events:

extension AppDelegate: ContactCenterEventsDelegating {
    func chatSessionEvents(result: Result<[ContactCenterEvent], Error>) {
        switch result {
        case .success(let events):
            print("Received events from contact center")
            DispatchQueue.main.async {
                //  Handle events here ...
            }
        case .failure(let error):
            print("chatSessionEvents failed: \(error)")
        }
    }
}

Set the delegate for ContactCenterCommunicator:

contactCenterService.delegate = self

To verify that a chat service is available, call checkAvailability() method:

contactCenterService.checkAvailability { [weak self] serviceAvailabilityResult in
    DispatchQueue.main.async {
        switch serviceAvailabilityResult {
        case .success(let serviceAvailability):
            print("Chat is \(serviceAvailability.chat)")
            self?.isChatAvailable = serviceAvailability.chat == .available
        case .failure(let error):
            print("Failed to check availability: \(error)")
        }
    }
}

To request a new chat session, call requestChat() method and subscribe for push notifications for the newly created chat session:

contactCenterService.requestChat(phoneNumber: "12345", from: "54321", parameters: [:]) { [weak self] chatPropertiesResult in
    DispatchQueue.main.async {
        switch chatPropertiesResult {
        case .success(let chatProperties):
            self?.currentChatID = chatProperties.chatID
            contactCenterService.subscribeForRemoteNotificationsAPNs(chatID: chatProperties.chatID,
                                                                     deviceToken: deviceToken) { subscribeResult in
                DispatchQueue.main.async {
                    switch subscribeResult {
                    case .success:
                        print("Subscribe for remote notifications confirmed")
                    case .failure(let error):
                        print("Failed to subscribe for notifications: \(error)")
                    }
                }
            }
        case .failure(let error):
            print("\(error)")
        }
    }
