I have an iOS app that I am working on and every time I change anything in the firebase db it notifies my app. I am looking to stop all those notifications as I want to implement notifications myself and just have firebase be a datastore.
I am using .observeSingleEvent everywhere but the app still gets notified every time the DB updates.
As you probably guessed I am new to Firebase but I was hoping some knowledgeable firebase person can help explain to me how to turn off all firebase notifications.
IMPORTANT: I do need to have the capability to do my own push notifications so I cannot simply stop the iOS App from registering for notifications. Right now Firebase and my notifications conflict and I get duplicates.
Thanks for any help!!
There is one way to make a firebase fire a push notification when node is changed. You should check Cloud Functions. There must be an information about when fire and what to change.

I wish to implement push notifications in my flutter app. Initially, I wanted to build something in-house to implement the notification until I realized the limitations that would eventually emerge later on. So I wish to use FCM or One Signal notification services for that matter.
I have a Postgres database and flutter app running on AVD. I am using API in PHP to display the data on the app.
Now how I wish the push notification to work; say I have a table 'A' in my DB, and whenever a new collection of rows is inserted into the table I wish to have the push notification sent to the app. I understood that services like FCM and One Signal send out the push notification to the app but my query is how do I configure my Postgres database to FCM or One Signal so that push notification is sent with the update made to the table in DB.
Please correct me if my question is misplaced.
Could anyone help me with relevant content or links? Thanks.
I'm using with success the flutter local notification plugin. Now I'm struggling for create a page with all notifications.
Is there a way to collect all incoming local notifications of my app (even if dismissed and/or not clicked) in a list (the classic notification page like FB etc.)
I only notice that I can track the tapped notification but not only the arrival notification.
Thanks!
This unfortunately is not possible, because notifications are not stored anywhere. They exist in memory on the device, until the user dismisses them, or they are replaced with a message of a similar ID, or the OS just removes them altogether.
Your best bet, is to generate a table on your mobile backend, that will store these notifications (the same ones that will be broadcasted to the users notification center), then get the app to read directly from this table, and store it on a local SQLite database.
These notifications that are broadcasted, will need to be sent from the backend itself, with the exact same content, as that being stored on the table I mentioned. This will ensure data integrity between the notification center, and that of the app.
[EDIT]
Please make sure that you use FCM (Firebase Cloud Messaging) for mobile push notifications. These are completely free, as per the documentation:
https://firebase.google.com/docs/cloud-messaging

I'm trying to create a Chat App. When the app enters background and if he receives a message, then a notification must appear.
What I understand is that FIRMessaging.sendMessage() sends something to the cloud. But how the other device is gonna receive it ? It cant be continually looking for messages that are targetted to him...
I would like to understand how to use this fonction and what are the parameters to pass in it. So far and with the current documentation, I couldnt do it.
[[FIRMessaging message]sendMessage:(nonnull NSDictionary *)message
to:(nonnull NSString *)receiver
withMessageID:(nonnull NSString *)messageID
timeToLive:(int64_t)ttl;
What should I put in the receiver ? It's userId in firebase ? or what ?
In the exemples they talk about SENDER_ID + "#gcm.googleapis.com"
which confuses me cause it looks like it's either my Id or the Id of the firebase App..
I cant even figure out if i'm trying to send an upstream or downstream message (dont understand)
Well all I can say is that I really get my head around it...

Thanks!
Firebase Cloud Messaging and Firebase Notifications (which is built on Firebase Cloud Messaging) handle this automatically for you. From the documentation of Firebase Notifications:
When your app is in the background on a user's device, notifications are delivered to the system tray. When a user taps on the notification, the app launcher opens your app. If you want, you can also add client message handling to receive notifications in your app when it is already in the foreground on the user's device.
I am building a TVOS app for the new Apple TV that needs to get notifications from a server to update it's display. Remote notifications are not allowed with TVOS, and it actually displays an error when you try to register the app for remote notifications.
With this being said, are there any alternatives to what I need?
To clarify:
- The app stays running indefinitely, showing a display.
- When the user adds content to the display, I want to notify any apps that are logged in to the same user to update the display.
- I cannot use remote notifications.
Please let me know if this makes sense, and thank you in advance for your help!
What part of the registration errors out for you? Notification dialogs and banners may not really make sense on tvOS, but can you send a silent push notification? All you need to do to register for these is
[application registerForRemoteNotifications];
You do not need to display the request dialog to the user for permission for silent notifications (you do need to have the remote notifications entitlement though.)
According to Apple's documents here, they allow CloudKit. CloudKit subscriptions rely on silent push notifications that I would assume would work on tvOS (without them it would severely cripple CloudKit)
If that still does't work, then you could create your own long polling connection (essentially, you would be making your own custom push notifications). It would only be able to send messages to devices that have the app opened however.
I guess you can have the app poll a web server at a given interval to check if any updates have been made...
I have implemented all recommended methods in AppDelegate to get working Remote Notifications service.
I can accept them while running, while launching and while turned off.
But there is an issue, since I can't work with many received notifications while in background. I can work only with latest notification.
What is recommended manual to do that? How can I got all notifications received while in background? Is it only solvable via manual call to my service provider (sender of apns data)?
With all the projects I've worked on there hasn't been a way to locally store this information if the push notification is dismissed. In all those cases we used a small file on the server that the app would connect to and pull when it became active again. There was also some place in the app where the user could see all their notifications which, again, were stored on the server for quick retrieval.
With the way I understand push notifications to be setup, if the notification is dismissed the system discards it. It'll perform anything it's supposed to do (such as update the badge number and play the correct sound) but any additional information specific to that notification is lost.
Not sure if this helps, but if you just want to know how many notifications you have missed while you were in background. You can create a variable which contains notification number and store this in the app every time you handle notification. When you come out of background and receive a new notification you can subtract the new number with the stored number to find out the number of missed notifications. I don't think there is a way where iOS can give you complete data associated with all the notification device have received while the app was in background.
The best solution is to keep a list of sent notifications with all relevant data on your server, so the app can access that data when it launches. Sending multiple notifications with data that is not stored on the server can be risky, because the application only receives the notification when the user opens the app from that notification, so if they tap on one notification, the app will only every receive that one.
If you have them all in a list on your server, the app can simply go and pull that list down, and process it, making sure no data is lost.
