- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler will not get Called when App run in foreground

Hi All,


I have an legacy app which was created for a couple of years ago, Recently We have to add to support ServiceExtension per apple request.


Before I implement the service extenion on my legacy project, I have created sample project by Xcode 11.2.1 and works fine.


on sample project, when App runs in foreground, If I send regular APNS with payload with mutable-content=1:


{"aps":{"alert":{"body":"myBody","title": "myTitle"},"mutable-content":"1"}}


it will invoke the method:

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

{


once put those implementention on my legacy project, it never get call when receiving the same payload as sample project, it will only get called with content-available: 1


Where should I check on the configuration? or something else?


Thanks in advance.

Just dealt with this yesterday...


Implement UNUserNotificationCenterDelegate of UNUserNotificationCenter.currentNotificationCenter.

And right on app launch, set that delegate, for example:

[[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];

The method:

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

Will indicate how the notification will be presented once received, for example:

completionHandler(UNAuthorizationOptionAlert | UNAuthorizationOptionSound | UNAuthorizationOptionBadge);


Then the method:

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler

Will indicate what to do after the user interacted with said notification. Don forget to call the completion handler!
Good luck!
