FCM Notification Method is not called in background mode

Question

I have made one sample demo for Push Notification with FCM. I am able to received Notification in Back Ground Mode as well as Foreground mode. But my question is:- When my application is in Background Mode Notification received but does not called any single Method so I can do action.

I agreed that when I have clicked on that method it will call one method but not in background.

Method is i have used

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler { 

}

- (void)userNotificationCenter:(UNUserNotificationCenter *)center  willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
{

}

Please Help Me guys I got stuck.I need it Thanks in Advance. I have read so many links but not able to solved my Problem.

Note:- Please keep in mind I have used Google clouding messaging:- FCM

I have used in Objective c

Pay Load Comes in this formate { "aps" : { "alert" : "You got your emails.", "badge" : 9, "sound" : "bingbong.aiff" }, "acme1" : "bar", "acme2" : 42 } — Hardik1344, Aug 22 '17 at 12:03

@ M Zubair Shamshad :Does "content-available" : 1 added from back end side or i have to add in application side if yes then where in application code? — Hardik1344, Aug 22 '17 at 12:12
can be added at back-end side. (from where you are sending notification) — M Zubair Shamshad, Aug 22 '17 at 12:13
About payload see [here](https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CreatingtheNotificationPayload.html) but yes just as Zubair said you must set `content-available` to `1` so your app would be awakened in backgrnd .Also related: [here](https://stackoverflow.com/questions/44425744/alternative-to-usernotificationcenterdelegates-willpresent-when-app-is-in-backg/44705892#44705892) and [here](https://stackoverflow.com/questions/42275060/what-is-difference-between-remote-notification-and-silent-notification-in-ios/42302369#42302369) — mfaani, Aug 22 '17 at 12:18

@hd1344 have you set FirebaseAppDelegateProxyEnabled type "Boolean" value "NO" in your info.plist. — Nishant Bhindi, Aug 22 '17 at 13:10

As per our discussion in comments under your question. Here are a few more things to be done to achieve your requirement. I m posting these points as you were not familiar with content-available thing.

Open your Xcode project and

1: In the Project Navigator, select your project.

2: In the editor, select your iOS app target.

3: Select the Capabilities tab.

4: Enable Push notification under capabilities.

5: Enable the Background Modes capability.

6: Enable the Remote notifications background mode.

Now if your notification payload contains content-available : 1 then your app would be awakened in background.

The system delivers notifications by calling the application:didReceiveRemoteNotification:fetchCompletionHandler: method of your app delegate. Use that method to initiate your desired operations.

Whatever things You have mentioned above I have already implemented ,Just waiting for back end person for setting "content-available : 1" in his Pay Load Code.Thank You — Hardik1344, Aug 22 '17 at 13:10
