Mobile Center Push

Mobile Center Push enables you to send push notifications to users of your app from the Mobile Center portal.

Prerequisite - Enable Apple Push Notifications service (APNs) for your app

Configure Apple Push Notifications service (APNs) for your app from your Apple developer account and Mobile Center portal before adding Mobile Center Push to your app.

Enable push notifications on your application

In Xcode's project editor, choose your target and click Capabilities. In the Push Notifications section, click the switch to turn it from OFF to ON.


Set up APNs

Log in to the Mobile Center portal, select your application, click on the Push button from the left menu then click Next to reveal the push notification settings UI:


  • On the bottom of the page, select Sandbox for initial development or Production for production version of your application.

  • Collect the following information:

    1. Prefix and ID

      • Go to your Apple developer account and select your application from the App ID list in Identifiers.

      • Copy the Prefix value from this window and paste it to the Mobile Center push settings.

      • Do the same with the ID value.


    2. Key ID

      • In your Apple developer account create a new key in Certificates, Identifiers & Profiles/Keys.

      • Make sure to check the APNs checkbox.

      • Fill in the key name

      • Press Continue then Confirm.


      • On the next screen, copy the Key ID value and paste it to the Mobile Center push settings.

      • Download the key file.


    3. Push Token

      • Open your key file with a text editor and copy the authentication token it contains.


      • On the Mobile Center push settings, paste this token to the Push Token field then click Done to complete this configuration.

For more information, refer to the Apple documentation.

[Optional] Enable silent notifications

Silent notifications give you a way to wake up your app so that it can refresh its data in the background (see Apple documentation). To enable silent notifications open Xcode's project editor, choose your target and click Capabilities. Turn on Background Modes and check the Remote notifications checkbox.


Add Mobile Center Push to your app

1. Add the Mobile Center Push module

The Mobile Center SDK is designed with a modular approach – you only need to integrate the services that you're interested in.

Integration via Cocoapods

If you are integrating Mobile Center into your app via Cocoapods, add the following dependency to your podfile and run pod install.

pod 'MobileCenter/Push'

Integration by copying the binaries into your project

If you wish to manually integrate the module, follow this documentation link.

2.Start Mobile Center Push

In order to use Mobile Center, you need to opt in to the service(s) that you want to use, meaning by default no services are started and you will have to explicitly call each of them when starting the SDK.

2.1 Add the import for Mobile Center Push

Open your AppDelegate.m file in Objective-C or AppDelegate.swift file in Swift and add the following import statements:

@import MobileCenter;
@import MobileCenterPush;
import MobileCenter
import MobileCenterPush

2.2 Add the start:withServices: method

Add MSPush to your start:withServices: method to start Mobile Center Distribute together with the other services that you want to use in your app.

Insert the following line to start the SDK in your app's AppDelegate.m class in Objective-C or AppDelegate.swift class in Swift in the didFinishLaunchingWithOptions method.

[MSMobileCenter start:@"{Your App Secret}" withServices:@[[MSPush class]]];
MSMobileCenter.start("{Your App Secret}", withServices: [MSPush.self])

Make sure you have replaced {Your App Secret} in the code sample above with your App Secret. Please also check out the Get started section if you haven't configured the SDK in your application.

2.3 [Optional] Receive push notifications if you have already implemented application:didReceiveRemoteNotification:fetchCompletionHandler method

If you or one of your third party libraries already implements application:didReceiveRemoteNotification:fetchCompletionHandler method, then follow step 4 to implement a callback to receive push notifications.

Intercept push notifications

You can set up a delegate to be notified whenever a push notification is received in foreground or a background push notification has been tapped by the user. The delegate may also be woken up when a notification is received in background if you have enable silent notifications and if the payload of the notification contains the content-available flag set to true.


If silent notifications are enabled and you push a notification with content-available: 1, then the delegate may be triggered twice for the same notification: when the notification is received in background and when it is tapped.

By default, iOS does not generate notifications when the push is received in foreground, you can use the delegate to customize the push experience when received in foreground or do a specific action when the application is launched by clicking on the push notification when received in background.

You need to register the delegate before starting MobileCenter as shown in the following example:

[MSPush setDelegate:self];
[MSMobileCenter start:@"{Your App Secret}" withServices:@[[MSPush class]]];
MSMobileCenter.start("{Your App Secret}", withServices: [MSPush.self])

Here is an example of the delegate implementation that displays an alert dialog when the message is received in foreground or a background push notification has been clicked:

- (void)push:(MSPush *)push didReceivePushNotification:(MSPushNotification *)pushNotification {
  NSString *title = pushNotification.title;
  NSString *message = pushNotification.message;
  NSMutableString *customData = nil;
  for (NSString *key in pushNotification.customData) {
    ([customData length] == 0) ? customData = [NSMutableString new] : [customData appendString:@", "];
    [customData appendFormat:@"%@: %@", key, [pushNotification.customData objectForKey:key]];
  if (UIApplication.sharedApplication.applicationState == UIApplicationStateBackground) {
    NSLog(@"Notification received in background, title: \"%@\", message: \"%@\", custom data: \"%@\"", title, message,
  } else {
    message = [NSString stringWithFormat:@"%@%@%@", (message ? message : @""), (message && customData ? @"\n" : @""),
                                         (customData ? customData : @"")];
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
    [alert show];
func push(_ push: MSPush!, didReceive pushNotification: MSPushNotification!) {
  let title: String? = pushNotification.title
  var message: String = pushNotification.message ?? ""
  var customData: String = ""
  for item in pushNotification.customData {
    customData =  ((customData.isEmpty) ? "" : "\(customData), ") + "\(item.key): \(item.value)"
  if (UIApplication.shared.applicationState == .background) {
    NSLog("Notification received in background, title: \"\(title ?? "")\", message: \"\(message)\", custom data: \"\(customData)\"");
  } else {
    message =  message + ((customData.isEmpty) ? "" : "\n\(customData)")
    let alert = UIAlertView(title: title, message: message, delegate: self, cancelButtonTitle: "OK")

Enable or disable Mobile Center Push at runtime

You can enable and disable Mobile Center Push at runtime. If you disable it, the SDK will stop updating the device token used to push but the existing one will continue working. In other words, disabling the Mobile Center Push in the SDK will NOT stop your application from receiving push notifications.

[MSPush setEnabled:NO];

To enable Mobile Center Push again, use the same API but pass YES/true as a parameter.

[MSPush setEnabled:YES];

Check if Mobile Center Push is enabled

You can also check if Mobile Center Push is enabled or not:

BOOL enabled = [MSPush isEnabled];
var enabled = MSPush.isEnabled()

Disable automatic forwarding of application delegate's methods to Mobile Center services

Mobile Center uses swizzling to automatically forward your application delegate's methods to Mobile Center services to improve SDK integration. There is a possibility of conflicts with other third party libraries or the application delegate itself. In this case, you might want to disable the Mobile Center application delegate forwarding for all Mobile Center services by following the steps below:

  1. Open your Info.plist file.
  2. Add MobileCenterAppDelegateForwarderEnabled key and set the value to 0. This will disable application delegate forwarding for all Mobile Center services.
  3. Implement the callbacks to register push notifications

    Implement the application:didRegisterForRemoteNotificationsWithDeviceToken: callback and the application:didFailToRegisterForRemoteNotificationsWithError: callback in your AppDelegate to register for Push notifications.

    - (void)application:(UIApplication *)application
        didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
      // Pass the device token to MSPush.
      [MSPush didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
    - (void)application:(UIApplication *)application
        didFailToRegisterForRemoteNotificationsWithError:(nonnull NSError *)error {
      // Pass the error to MSPush.
      [MSPush didFailToRegisterForRemoteNotificationsWithError:error];
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
      // Pass the device token to MSPush.
      MSPush.didRegisterForRemoteNotifications(withDeviceToken: deviceToken)
    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
      // Pass the error to MSPush.
  4. Implement the callback to receive push notifications

    Implement the application:didReceiveRemoteNotification:fetchCompletionHandler callback to forward push notifications to the Push service.

    - (void)application:(UIApplication *)application
        didReceiveRemoteNotification:(NSDictionary *)userInfo
              fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
      BOOL result = [MSPush didReceiveRemoteNotification:userInfo];
      if (result) {
      } else {
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
      let result: Bool = MSPush.didReceiveRemoteNotification(userInfo)
      if result {
      else {
