ios local push notification after app killed - ios

Question

Hi i i have a local push notification problem.
I implemented in-app language change function in my app.
and i have to restart the app after changed for reflect changes all part of my app. so i use abort() method.
before abort app i scheduled notification like this
UNMutableNotificationContent* content = [[UNMutableNotificationContent alloc] init];
content.title = [NSString localizedUserNotificationStringForKey:#"Hello!" arguments:nil];
content.body = [NSString localizedUserNotificationStringForKey:#"Languaged changed. Touch to restart." arguments:nil];
content.sound = [UNNotificationSound defaultSound];
// Deliver the notification in five seconds.
UNTimeIntervalNotificationTrigger* trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:3 repeats:NO];
UNNotificationRequest* request = [UNNotificationRequest requestWithIdentifier:#"FiveSecond" content:content trigger:trigger];
// Schedule the notification.
UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];
[center addNotificationRequest:request withCompletionHandler:nil];
abort();
i want to user come back to app by touching alert
but push message didn't come at all the time. sometimes it was came
and doesn't work again.
please help me if you know something about this issue.

Answer 1

Call abort() in completion handler:
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
abort();
}];
But anyway, calling abort() isn't good practice.

You shall not exit app (someone already posted it here https://stackoverflow.com/a/356342/6429711 and I believe Apple have it somewhere in guidelines).
You can change language without quitting app. When you generate app multiple bundles are generated. You can change localisation from separate bundles then.
Example:
extension String
{
// Get selected language
var localized: String {
return NSLocalizedString(self, tableName: nil, bundle: currentLanguageBundle, value: "", comment: "")
}
}
Where currentLanguageBundle is bundle based on the currently selected language.
