I am working on an app, which is available to receive notifications from server. I used UILocalNotification, and my app can receive informations from server with foreground and background mode, but I don't know how my app can do it when it is killed by user. In fact, I know that Facebook message app can do it easily, we always receive notifications any time. Please, give me some solutions, thanks so much.
plz read this link
https://developer.apple.com/library/mac/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/IPhoneOSClientImp.html
push notifications payload look like this
{
"aps": {
"badge": 10,
"alert": "Hello world!",
"sound": "Default"
}
}
if you add message in alert. then your notification will show when your app in background or killed.
Read this link for all the steps which you have required to setup the push notification :

I am using APNS push with content-type = 1. I receive the payload and fire using local notification.
this works fine in background and foreground mode
but when app is killed I get nothing.
what is the solution? I have seen people saying something about VOIP apps
but mine is not a VOIP app..
Some said to check Pushkin framework?
Any guidance?
Update
with this Json format I received notification when app was in killed state.. I checked on lower version 9.3 iOS.. have to check on iOS 11..
{
"aps": {
"content-available": 1,
"alert": "custom message ",
"badge": 1,
"sound": "solemn.wav"
},
"id": "55",
"data": "your data"
}
I don't think it can be done if your app is not a VOIP app. But, if you want to change the appearance of a push notification, you may want to look at the Notification Service Extension.
You have to include mutable-content flag as 1 in your payload inside aps. You cannot use content-type flag with this notification. Also, you have to show user something or the other after you have received the payload. Also, it is available in iOS 10 and above only.
Even with all these constraints, you can do some amazing things with this extension which were not possible earlier.
You can now show media attachment in the notification.
You can download small content or hit an API.
You can modify earlier sent push notification.
You can create a local notifcation center in your app.
When my app is running in foreground and I send a notification from my web server (PHP), the iPhone does not alerts that the message arrived. I know that the message arrives because I save it on internal database and I can see it in a viewcontroller.
That's my JSON packet:
{
"data": {
"mensagem":"msg",
"dataEnvio":"2017-01-2016:06:58"
},
"content_available":true,
"time_to_live":3600,
"priority":"high",
"notification":{
"title":"new",
"sound":"default",
"body":"msg"
},
"registration_ids":["..."]
}
The same problem does not happens on Android.
Someone know what this is happening?
When the app is in the foreground the notification portion of the push notification is neglected in both android and ios. I am sure that you are creating the push notification yourself in android on the handling function OnMessageReceived so that it appear when you are foreground.
I have a (Nativescript) iOS client app that should be able to receive a push notification sent by Firebase. It actually does receive data when the app is in the frontend, but as the documentation states, iOS should detect an incoming notification (when the app is in the background) and display the notification.
This last part just doesn't seem to work. I tried a lot, but can't figure out what's going on here.
I'm sending the notification by using the Firebase console. There's just nothing happening on my iPhone here, no sound, no badge, nothing!
While Firebase claims everything just works fine...?!
Can anybody help me?
Okay, so I guess I wasn't very specific, so let me add some code below.
I am posting this code to Firebase (https://fcm.googleapis.com/fcm/send) to trigger the push notification:
Content-Type:application/json
Authorization:key=[MY_KEY_HERE]
{
"to" : "[FIREBASE_DEVICE_ID_HERE]",
"priority": "high",
"notification" : {
"body" : "Howto write a great body?",
"title" : "Some title...",
"sound" : "default"
}
}
As you can see, this is a notification message, not a data message, so it should trigger a popup, badge, sound, or whatever on iOS...right?
As I mentioned before, I am able to receive this json data, but only if my app is in the foreground... So the Firebase-device-id is absolutely right and also is the authorization key.
What else should I try?
FCM Data-Messages are not displayed while the app is in background :
On iOS, FCM stores the message and delivers it only when the app is in the foreground and has established a FCM connection.
Source here : FCM Documentation
Be sure to sens Notification and not a Data message
Maybe you are disconnecting from Firebase with such command
[[FIRMessaging messaging] disconnect];
Could you tell if you can send message via APNS from your computer (without Firebase)? Example file to send such message can be found somewhere in this tutorial https://www.raywenderlich.com/123862/push-notifications-tutorial .
I´m having trouble on receiving push notifications (background) on a specific device running iOS 10. Other phones with iOS 9 are doing fine.
Although if I open the app the notification shows a banner that I implemented. Why does not show anything in background state?
Reading the firebase documentation something made me a little confused
According to a github firebase example on the following link https://github.com/firebase/quickstart-ios/blob/master/messaging/FCMSwift/AppDelegate.swift, there is a comment in the didReceiveRemoteNotification method that says:
// If you are receiving a notification message while your app is in
the background, // this callback will not be fired till the user taps
on the notification launching the application. // TODO: Handle data of
notification
So it my app is in background, does not apple do the whole thing to make that default iOS notification?
Does the content_available value interfere on this? I also send notification and data values.
Here is an example of the JSON I send:
{
"content_available": true,
"priority": "high",
"data": {
"post_id": "...",
"push_id": "..."
},
"notification": {
"title": "...",
"body": "..."
},
"registration_ids": ["xxxx"]
}
The expected behaviour would be:
App dead: the system will show the notification
App background: the system will show the notification and call the didReceiveRemoteNotification method.
App active: the system will NOT show de notification and call the didReceiveRemoteNotification method.
Right?
Your assumptions are correct except for number 2. There are several cases where apple will not call didReceiveRemoteNotification you even if you set the content_avaialable.
1) Device has low battery and is in power saver mode
2) App has "background app refresh" disabled
3) Other undocumented scenarios where apple decides not to wake up your app. Apple reserves the right to not deliver notifications for performance reasons.
Having said that, if the user taps the notification you will always get the payload in didReceiveRemoteNotification.
I have a problem. When my App is Terminated by the user, push notifications are not detected by the application. The push notification is sent with content_available = true.
What should I do?
This is default system behaviour. If you Application is terminated by the user (from the App switcher), Silent Push Notifications (content_available = true) will not wake the Application, i.e. Application:didreceiveremotenotification will not be called.
If you want the user to be notified, do not send a Silent Push Notification. Send a normal push notification which will show up in the user's notification tray.
That is the way how it works on iOS.
If you app is not running at all, your app receive no push notifications at all. Only if the user swipe over one of your push notifications on the lock screen or the notification center your app will be started and you will be notified that your app was started because of the push message.
If you app is in the background, you actually can handle push notifications by enabling "run in background" support.
I'm talking iOS9 and earlier here. Not sure if the behaviour has been changed in iOS10. But if you are coming from Android then you have to accept that push notification handling works completely different on iOS than on Android.
Sending the notification with the content_available as disabled. content_available = 0
The content_available field is used for sending silent push notifications to process in the background and will not display as a notification.
See documentation : https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/TheNotificationPayload.html#//apple_ref/doc/uid/TP40008194-CH107-SW6
Hope this helps,

Make sure that in your push notification payload you are adding priority:"high". It will ensure that your app will receive a Push Notification in background or closed mode.
{
"to" : "/topics/{userId}"
"content_available":true,
"priority":"high"
"notification" : {
"title": "",
"body":""
},
"data" : {
//custom key value pairs
}
}
