Push Notifications in iOS 11

Question

Before iOS 11 , when the app receive a notification while running in the foreground , the notification will not appear unless using a custom view to show it. Is the way we handle the received push notifications while app is running in the foreground changed in iOS 11?

Answer 1

Try this in Appdelegate class

func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    completionHandler(.alert)
}

this is the delegate calls when app is in foreground and if you want to show alert as well then add .alert in completionHandler.

It is added in iOS 10 onwards
