IOS unable to receive notification

[PratikG9]

Issue:
Not able to receive notification on iOS device

What I've tried:
I've followed this documentation to implement notifications in iOS,
https://rnfirebase.io/docs/v4.2.x/notifications/ios

iOS implementation:
AppDelegate.m

#import "AppDelegate.h"

#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#import "RNFirebaseNotifications.h"
#import "RNFirebaseMessaging.h"

@import Firebase;

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{  
  /// Firebase configuration
  [FIRApp configure];
  [RNFirebaseNotifications configure];
  
  NSURL *jsCodeLocation;

  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"XYZApp"
                                               initialProperties:nil
                                                   launchOptions:launchOptions];
  rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  return YES;
}

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
  [[RNFirebaseNotifications instance] didReceiveLocalNotification:notification];
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo
fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler{
  [[RNFirebaseNotifications instance] didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
}

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
  [[RNFirebaseMessaging instance] didRegisterUserNotificationSettings:notificationSettings];
}

@end

Application's Home File

componentDidMount() {
      /// get permission and reuest FCM token
      this.notificationRequestPermission()

      /// Triggered when a particular notification has been displayed
      this.notificationDisplayedListener = firebase.notifications().onNotificationDisplayed((notification) => {
          // Process your notification as required
          // ANDROID: Remote notifications do not contain the channel ID. You will have to specify this manually if you'd like to re-display the notification.
          console.log("NOTIFICATION DISPLAYED", notification)
      });

      /// Triggered when a particular notification has been received
      this.notificationListener = firebase.notifications().onNotification((notificationobj) => {
          // Process your notification as required
          console.log("NOTIFICATION RECEIVED", notificationobj)               
      });

      /// Listen for a notification being opened
      
      // Foreground or Background
      this.notificationOpenedListener = firebase.notifications().onNotificationOpened((notificationOpen) => {
        // Get the action triggered by the notification being opened
      });

      // App closed
      firebase.notifications().getInitialNotification()
      .then((notificationOpen) => {
        if (notificationOpen) {
          // App was opened by a notification
        }
      });
}

Can somebody guide me in this, is there any other implementation way to receive notification in iOS

I think I have a similar problem except my messages are showing up, but in the wrong context. I have both remote Messaging and Notifications enabled, yet when I send a Notification+Data message from the FCM Console, the message is received on firebase.messaging().onMessage() instead of in firebase.notifications().onNotification(). From the docs it seems like messages from FCM console should be handled by the Notifications module, but they're actually be handled by the Messaging module.

With that in mind, have you tried following the instructions in the Cloud Messaging setup, i.e. listen with firebase.messaging().onMessage() and seeing if your notification pops up there instead?

[PratikG9]

@TimMun thanks for the suggestion

Yes I've tried with firebase.messaging().onMessage() and able to get message. but as per the documentation it should be used in case of data messages only. and how can I get notification when app is closed with onMessage().

there is one more thing I'd like to mention, my delegate methods are not calling.

It appears as if RNFirebase documentation is missing a few required steps. After adding the below code after [RNFirebaseNotifications configure]; in AppDelegate.m, remote notifications worked for me.

// Setup Notifications
  if ([UNUserNotificationCenter class] != nil) {
    // iOS 10 or later
    // For iOS 10 display notification (sent via APNS)
    [UNUserNotificationCenter currentNotificationCenter].delegate = self;
    UNAuthorizationOptions authOptions = UNAuthorizationOptionAlert |
    UNAuthorizationOptionSound | UNAuthorizationOptionBadge;
    [FIRMessaging messaging].delegate = self;
    [[UNUserNotificationCenter currentNotificationCenter]
     requestAuthorizationWithOptions:authOptions
     completionHandler:^(BOOL granted, NSError * _Nullable error) {
       if (error) { NSLog(@"%@", error); }
     }];
  } else {
    // iOS 10 notifications aren't available; fall back to iOS 8-9 notifications.
    UIUserNotificationType allNotificationTypes =
    (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
    UIUserNotificationSettings *settings =
    [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
    [application registerUserNotificationSettings:settings];
  }
[application registerForRemoteNotifications];

Make sure to add the required import or else your code won't compile
#import <UserNotifications/UserNotifications.h>

[TimMun]

Can confirm this worked for me, now notifications sent from FCM composer are coming thru on notifications().onNotification(). Thanks!

[chrisbianca]

As per the documentation, this block of code is handled by the requestPermission method: https://rnfirebase.io/docs/v4.2.x/notifications/receiving-notifications#2)-Request-permissions

[yarian]

@chrisbianca Can you please clarify something, we just spent days debugging this issue and I think I just understood the source of it and a way to avoid future confusion.

We were experiencing notifications from our app not arriving, not even when calling APNS directly using the APNS token. (Although, only for some users). We were not calling firebase.messaging().requestPermission();. We realized this and we added the call, but like so:

 return firebase
      .messaging()
      .hasPermission()
      .then(enabled => {
        if (!enabled) {
          firebase
            .messaging()
            .requestPermission()
            .then(() => {
              this._initializeListeners()
              Tracking.track('User just granted notifications')
            })
            .catch(() => {
              Tracking.track('User denied notifications')
            })
        }
      })

We still had reports of some people not receiving them. When we (almost by accident) added code similar to chriswang's above they started working for those people.

So I have a few questions/points I'd like to raise.

1. Where does requestPermission register for notifications? Here?
2. Is it required that we call requestPermission? If so, how often? (Every time APNs token might have changed?) The current docs make it sound like it's optional, only if you're having permissions issues. For example: (emphasis mine)

If the user has not already granted permissions, then you can prompt them to do so, as follows:

Before you are able to send and receive Notifications, you need to ensure that the user has granted the correct permissions:

The second example above is slightly misleading, because it's not true that we just have to ensure they granted permissions, we have to do it by calling a specific react-native-firebase method that does more than just that.

3. If I'm understanding right, and requestPermission also registers for notifications, I would like to suggest that that is separated unto its own thing to make it much more explicit.

Instead of having docs that suggest you do:

firebase.messaging().requestPermission()
  .then(() => {
    // User has authorised  
  })
  .catch(error => {
    // User has rejected permissions  
  });

Have the default instructions be:

firebase.messaging().requestPermission()
  .then(() => {
    firebase.messaging().registerForNotifications()
  })
  .catch(error => {
    // User has rejected permissions  
  });

That way it's clear, even if you're somehow getting a permissions dialog without adding this code, that you still have to register for notifications.

Hi everyone!
Encountered a similar problem and all of this suggestions don't work for me. Solved by setting FirebaseAppDelegateProxyEnabled to yes in info.plist and reinstalling app on test iPhone. Hope it helps somebody.

[malangaveuday]

@chriswang101
Thank you, man
Your solution worked for me

[Bloueco]

Worked for me too man. Thanks @sanjcho !!!!!

[faustoct1]

still not working for me.. does have any config on AppDelegate.m ?!?

[Sunrise17]

When i delete and reinstall the app, FCM Console sending notification through fcmToken, however when i stop and run the code again, iOS device stopped receiving notification from Console. I have also added FirebaseAppDelegateProxyEnabled (yes) in info.plist. However issue has not been solved yet. I am planning to add cloud function to send notification, but even console has such reliability issue how i will go on?

[MinaFSedrak]

It's working ONLY while testing for a specific Fcm Token... not working while publishing a campaign (for all users). Any updates !????

[jsuryahyd]

It worked for me when I used firebase.messaging.onMessage() listener, but only on foreground. cannot get notifications in background and when app is closed.
Also, the notification object inside the listener is different to that of android i.e the notificationId key is not present in ios notification. So, while building notification, I had to pass .setNotificationId(nO._messageId), otherwise the display function throws error.

@yarian thank you so much - For everyone not receiving pushes - request Permission is required even if you have pushes already enabled!! I am migrating a swift app to react native and wasn't receiving pushes even though I had the token. Just calling requestPermission fixed it.
