I am using FCM notification for my app. When my app is in background or foreground I am receiving notification. But when my app is terminated that means closed from task then I am not receiving any notification. I searched about this and I am confused is it work when the app is terminated? I just need to know is it work or not when the app is terminated.
If it works when the app is terminated then I will go for next step for my app otherwise I will stop my implementation that's why I am not sharing any code. I followed this link
Beware with fcm on iOS, there are 2 ways of sending and receiving data; one is upstream/downstream messages the other is the push notifications. If you are using upstream/downstream messages the fcm connection is closed after the app is suspended, new messages will not wake your app. You may use push notifications instead but of course the downside is that they are push notifications you don't have much control over them.

Recently Apple changed its way of handling VoIP notifications. Now they force you to use CallKit in the same run loop in order not to throw your notification away. The trace I get is this one
Apps receving VoIP pushes must post an incoming call (via CallKit or IncomingCallNotifications) in the same run loop as pushRegistry:didReceiveIncomingPushWithPayload:forType:[withCompletionHandler:] without delay.
When you get this warning three times, the system is "dropping your notifications on the floor".
The problem here is that I'm developing a hybrid VoIP app using the phonegap-plugin-push, and I'm afraid that the on notification event is not fast enough (or at least not the same run loop) for iOS.
Did anyone face this issue?
I've thought of changing to regular push notifications, but I can't find a way to make my app relaunch when it's killed and execute some code (launch CallKit, for example).
Edit:
I'm trying this approach with push notifications and I already configured the background modes. I noticed that sending the "content-available" and some data, like "badge", or "alert" in the notification, the app is launched if it went to background recently. After 15 minutes in the background the push notification arrives but the app doesn't launch anymore
Thank you in advance.
Our app uses CallKit and push notifications, and it launches when a push notification arrives for a new incoming call. It has to be configured in the project build and run once to register with iOS for this, though.
I found a solution:
Since iOS changed its policy about handling voip push notifications, it forces you to report a new incoming call when receiving the voip: https://forums.developer.apple.com/thread/117939
This plugin does it: https://github.com/mattkhaw/cordova-plugin-callkit
It merges two plugins (WebsiteBeaver/CordovaCall and Hitman666/cordova-ios-voip-push). It worked for me. I just had to remove the receiveCall from the javascript and tweak a little bit the plugin.
The methods related to the voip notifications register are in the cordovaCall class, so it is pretty straightforward to work with.
if My app works at background, can I use silent push to wake app and get the VOIP call?
I used "jpush" to post a silent push which can work when connecting my idevice with Xcode and run APP.
If my idevice doesn't run APP with Xcode, I can not receive the silent push at background (only receive at foreground.)
Is it possible to use silent push to wake up APP and get VOIP call?
Did I get something wrong??
Yes. If your application does VoIP calling then it's possible to use PushKit:
Overview
The PushKit framework sends specific types of notifications — such as VoIP invitations, [...] — directly to your app for processing. [...]
Unlike user notifications, which are supported by the UserNotifications framework, PushKit notifications are never presented to the user — they don't present badges, alerts, or sounds.
PushKit notifications offer the following advantages over user notifications:
If your app isn't running, the system automatically launches it upon receiving the notification. [...] For more information, see Local and Remote Notification Programming Guide.
Your app is given runtime to process the notification, even if it's running in the background.
[...]
Like many here, I was looking for a reliable way to deliver push notifications to an app for background processing. I finally decided to use PushKit and all works well and the app was accepted into the AppStore, even though it's not a VoIP application. I'm using the AWS SNS (Simple Notification Services) to handle the backend push processing. However, even VoIP notification delivery will be throttled by iOS if you send excessive push notifications. As a simple test, I can send several VoIP notifications over 2 - 3 min and they will deliver promptly and processed by the app in the background. After I wait about 10 minutes (after locking the iPad and waiting for the application to be put to sleep by iOS) a subsequent VoIP push won't be delivered promptly by iOS. AWS is pushing the notification, but iOS is not delivering it to the app. I know this because as soon as I plug in the device, the notification is processed by the application. As an aside, if the device is left plugged in, all notifications deliver and process promptly.
So my question is this: Have others noticed this behavior with VoIP pushes also? Even though the iOS docs indicate that VoIP pushes are delivered immediately, it appears that iOS does throttle them if it considers the pushes "excessive" over some period of time.
I guess, When you keep your app in background then you receives push notification. but when your app is in terminated then don't receive push notification.
Possibly your app gets crash when it is in killed ( terminated ) state.
Pushkit silent notification is always with higher priority and works well all the time.
Try below things to find out cause and solution.
(1) Debug your app in killed ( terminated ) state, like app is crashing or not
(2) Send silent notification with simple php code using pem and certificates ( Both case background and killed ( terminated ) )
(3) Check pushkit integration steps, if your app is not registered for VOIP, then it would not receive silent notification.
Debug pushkit notification in terminated state
Put debug pointer on delegate methods
Go to edit scheme
Select run option then Launch -> Wait for executable to be launched
Send push kit payload from back end
Once you get payload on device
it will automatically invoke and debug pointer will invoke at delegate methods.
Refer some material
We need to calculate some numbers and display the calculations in local notification on receiving a silent push message from the server.
This works when the app is active/open in background.
This does not work if the app is killed/not in background.
So is there anyway to perform tasks when app is closed and the silent push arrives?
FYI I have enabled background fetch.
Apple's Documentation states:
Note: The ability of APNs to deliver remote notifications to a nonrunning
app requires the app to have been launched at least once.
On an iOS device, if a user force-quits your app using the app
multitasking UI, the app does not receive remote notifications until
the user relaunches it.
The second sentence pertains directly to your question; likely not the answer you hoped for...

iOS push notification in delayed Network
We are developing iOS VOIP app it supposed work in 5/6 second delayed network in running background, Our observation is in 4 second delayed network any push notification does not arrive from Apples APNS server to our VoIP app as a result incoming call missed when it goes suspended.
Any help would be appreciated!
Thanks
You can not rely on push notification for such feature, push notification may never arrive.
if you want to use third party app i will suggest you to use
