iOS not receiving Firebase Push Notification sent through the API

阅读更多关于 iOS not receiving Firebase Push Notification sent through the API

问题 I'm using Google's Firebase Cloud Messaging to send push-notifications to my iOS and Android applications. The push-notifications sent through the Cloud Messaging console work just as intended, however when I send a push-notification through the API, the iOS application only receives it when in foreground. On Android, it is working correctly (both in foreground and background). Reading the documentation, the iOS system would then transfer the "notification" object to the system tray, as

How to refresh FCM Token on user Logout?

阅读更多关于 How to refresh FCM Token on user Logout?

问题 I am getting the FCM first time and save it to my userDefaults. Now When user logs out, how can I refresh the FCM token again? I have searched the docs and many other asked questions, but didn't find a better solution. Thanks in advance. 回答1: The FCM Token is an Instance ID token, it represents the installed app and not the signed in user. Generally once the app remains installed it will have the same token no matter what user is signed in. You would have to manage what user is associated to

IOS data notifications with FCM

阅读更多关于 IOS data notifications with FCM

问题 I am using FCM (firebase cloud messaging) to send "custom" data notifications to an IOS app. From what I understand, we use notification messages when you want FCM to handle displaying a notification on your app's behalf. And we use data messages when you just want to process the messages only in your app. It's by design. Problem I am facing is that that Device/InstandID token is unique to installed app and not the user logged in the app. So to solve this, I am sending intended user tag in

Keep data from the Firebase Realtime Database always in sync

阅读更多关于 Keep data from the Firebase Realtime Database always in sync

问题 I'm currently re-working an app of mine which updates it's internal SQLite database by fetching raw data from an website, not an official API. As this is quite error-prone I'd like to move the data processing out of the client into an backend server. The idea is to have a script running on the server multiple times a day - similar to the client behaviour before - and storing the data in a Firebase Realtime Database. Then, all clients no longer have to process the data themselves but rather
