Not receiving notifications when app is closed IOS

[darkcoderrises]

I have an app which uses react-native-firebase. I followed the initialisation steps provided for installing the app and for cloud messaging. Now when I use firebase console to send notification to a single user (haven't tried sending to a bunch, but I guess result would be the same), I receive the notification if the app is open, otherwise not. I read somewhere that when app is closed, one doesn't receive notification in the code, rather user see's a notification in notification bar and when clicked on, it invokes getInitialNotification().

1. Target Platform : iOS
2. Development Operating System: macOS Sierra
3. Build tools: Xcode 8.2.1
4. React Native version 0.45.1
5. RNFirebase Version 2.0.4

Podfile:

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'FroogalMerchant' do
  pod "Yoga", :path => "../node_modules/react-native/ReactCommon/yoga"
  pod 'React', :path => '../node_modules/react-native', :subspecs => [
    'BatchedBridge', 
    'Core',
    'RCTText',
    'RCTWebSocket',
    'RCTNetwork',
  ]

  pod 'Firebase/Core'
  pod 'RNFirebase', :path => '../node_modules/react-native-firebase'  

  pod 'Firebase/Analytics'
  pod 'Firebase/Messaging'

  target 'FroogalMerchantTests' do
    inherit! :search_paths
    # Pods for testing
  end

end

Notification Listener component

import React, {Component} from 'react'
import {View, Platform} from 'react-native'
import firebase from '../utils/Firebase.js'

export default class NotificationListener extends Component {
  componentWillMount() {
    firebase.messaging().onMessage((message) => console.log('message', message));
    // This gets logged only when the app is open
    // Nothing happens when app is closed, no notification is shown either


    firebase.messaging().getInitialNotification()
      .then((notification) => {
        console.log('Notification which opened the app: ', notification);
      });
    // This is never called
  }

  render() {
    return (
      <View style={{width: '100%', height: '100%'}}>
        {this.props.children}
      </View>
    );
  }
}

Notification I am sending:

{
"registration_ids" : [""],
"notification": {
"title" : "Hi",
"body" : "Heyy"
},
"priority": "high"
}

@darkcoderrises Are you seeing the notification popup in the OS whilst the app is closed / in the background? Or are you not receiving this either?

[darkcoderrises]

@chrisbianca No I am not receiving.

[chrisbianca]

Have you called firebase.messaging().requestPermissions()? This is required on iOS so that the user gives the app permission to send notifications.

[darkcoderrises]

Yeah I call request permission at the start of the app. I receive notifications when app is open, but not when the app is closed.

[chrisbianca]

Have you enabled:

1. The push notifications capability
2. Remote notifications under the background modes capability?

If you're not receiving the notifications when in the background, this is a setup issue with FCM, not with react-native-firebase

[darkcoderrises]

Yeah, I have enabled them both. Is there anything else that is required for me to configure for background notifications?

[Jobeso]

Yes,
I got a similar issue. You need to give firebase an authentication certificate in the firebase settings.
For more: See here on firebase .
Another thing you can try is debugging. You can take this code and integrate it, call the screen and then close the app. 10 seconds after this code is executed, it will display a notification which is locally. Just to test you did everything right.

firebase.messaging().scheduleLocalNotification({
        fire_date: new Date().getTime() + 10000, // RN's converter is used, accept epoch time and whatever that converter supports
        id: `123456`, // REQUIRED! this is what you use to lookup and delete notification. In android notification with same ID will override each other
        body: `Your notification body"`,
        title: 'Your title',
      })

[darkcoderrises]

I am getting the local notification and I have followed the procedure as in the link provided. But I still can't receive notification when it is closed.
@Jobeso any other suggestion?

[Jobeso]

maybe there is a problem with this:

{
"registration_ids" : [""],
"notification": {
"title" : "Hi",
"body" : "Heyy"
},
"priority": "high"
}

Sending a message from your api should look like this:

firebase.messaging().sendToDevice(notificationId, {notification: {title: 'hey', body: 'test',},}, {priority: 'high',})

[darkcoderrises]

@chrisbianca @Jobeso I receive the notification in the objective-c code (AppDelegate.m).

`

• (void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo {
  NSLog(@"%@", userInfo);
  NSLog(@"%id", application.applicationState);
  NSLog(@"userinfo->%@", [userInfo objectForKey:@"aps"]);

  [RNFirebaseMessaging didReceiveRemoteNotification:userInfo];
  }

• (void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo
  fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler{
  NSLog(@"%@", userInfo);
  NSLog(@"%id", application.applicationState);
  NSLog(@"userinfo->%@", [userInfo objectForKey:@"aps"]);

  [RNFirebaseMessaging didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
  }`

from where it is supposed to be passed to rn firebase messaging. I think that is the point when it should create a notification.

Any luck solving this? i'm having the same issue

[sonnn]

I have the same issue with this and what i did to solve is put this code request for permission after [[UNUserNotificationCenter currentNotificationCenter] setDelegate:self]; and before return YES

if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_1) {
        // iOS 7.1 or earlier. Disable the deprecation warnings.
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
        UIRemoteNotificationType allNotificationTypes =
        (UIRemoteNotificationTypeSound |
         UIRemoteNotificationTypeAlert |
         UIRemoteNotificationTypeBadge);
        [application registerForRemoteNotificationTypes:allNotificationTypes];
#pragma clang diagnostic pop
    } else {
        // iOS 8 or later
        // [START register_for_notifications]
        if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_9_x_Max) {
            UIUserNotificationType allNotificationTypes =
            (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
            UIUserNotificationSettings *settings =
            [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
            [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        } else {
            // iOS 10 or later
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
            // For iOS 10 display notification (sent via APNS)
            [UNUserNotificationCenter currentNotificationCenter].delegate = self;
            UNAuthorizationOptions authOptions =
            UNAuthorizationOptionAlert
            | UNAuthorizationOptionSound
            | UNAuthorizationOptionBadge;
            [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:authOptions completionHandler:^(BOOL granted, NSError * _Nullable error) {
            }];
#endif
        }

        [[UIApplication sharedApplication] registerForRemoteNotifications];
        // [END register_for_notifications]
    }

This comes from firebase quickstart iOS and same with requestPermission. Notice both are successful asking permission. But requestPermission cannot receive notification when app close. Not sure why. Can anyone look into this?

[kevando]

For me I fixed this by adding my cert to the firebase web console.

But I am wondering where is all the documentation for this? Is this everything???

Thanks for reporting. We're aware of lots of issues with notifications and will be addressing them all as part of the v3.2.0 release stream. Please see #595 for updates.
