IOS 14 UNNotificationPresentationOptions.list, .banner vs alert


Hello I am trying to display some notification datas. In my notification I have a notification id to react deferently based on the pushed information.

I just cannot see what are those new UNNotificationPresentationOptions.

in my

userNotificationCenter(_: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)

I have

 if notification.request.content.userInfo[keyName] as? String == "someId" {
     // Bla bla stuffs
     if #available(iOS 14.0, *) {
         completionHandler([.list, .banner, .sound])
     } else {
         completionHandler([.alert])
     }
  } else if ...

But when using [.banner] or [.list] or [.banner, .list] (without .alert) I just got nothing in foreground. In an ideal world I'd love to have the notification listed in the Notification center and display relevant information in my app (before calling completion handler).

Am I using thoses options right ?


Solution

    • [.list] will only show the notification in the notification center (the menu that shows when you pull down from the top)
    • [.banner] will only pop down a banner from the top like a normal push notification
    • [.list, .banner] will do both: show the banner and also make sure it's on the list.

    [.alert] does essentially the same as having [.list, .banner], from what I can tell. They just added these two options to give more granular control.

    I just tested this locally and it did what I expected, so if it doesn't work for you it may not be hitting those lines. Did you add some breakpoints to verify that those lines were getting hit?
