iOS Push Notification containing only numbers is not displayed

Question

I am using One Signal to send push notifications. However, if the notification content body contains only numbers it is not displayed.

The phone vibrates and even the badge number increases as expected but nothing displays. It happens both on iOS 9 and 10.

If I log the content I can see the numbers so it comes through perfectly but it doesn't display.

Any ideas what could be causing this?

Two things. 1. The payload should look like this `{"aps":{"badge":3}}` 2. Settings to show badge for the app should be turned on. — iphonic, Feb 07 '17 at 18:15
I think you misunderstood my question. I can increase the badge number thats not a problem. However if the body of the notification is a string containing only numbers it doesn't display. — Balázs Vincze, Feb 07 '17 at 18:17
So you have confirmed that the exact same code works and displays the local notification if any alpha characters are included? — wottle, Feb 07 '17 at 18:57

Okay, so here is my solution:

I do not know if it is a OneSignal bug or an iOS bug but it seems as if the notification only contains a content value with numbers only, it won't show. The phone vibrates, but nothing shows up.

Make sure you include something in your title field as well (these can be numbers only), and then your notification with a number only content will display properly.

Hope this helps someone!

Have you tried sending a non-numeric message with no title field? I just want to confirm that it is only a numeric message with no title field that is a problem. – wottle Feb 09 '17 at 17:22
Good to know. Thanks for the clarification! – wottle Feb 09 '17 at 17:25
Also ran into this. Must be a OneSignal bug (or weird spec) – Will Dec 08 '19 at 15:11

You will need to handle the notification from app delegate file and show the message. You should get the complete notification body within user info parameter of didReceiveRemoteNotification method of AppDelegate. You will need to retrieve the info from it and show alert.

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {

    println("Recived: \(userInfo)")
   //Parsing userinfo:
   var temp : NSDictionary = userInfo
   if let info = userInfo["aps"] as? Dictionary<String, AnyObject> 
            {
                var alertMsg = info["alert"] as! String
                var alert: UIAlertView!
                alert = UIAlertView(title: "", message: alertMsg, delegate: nil, cancelButtonTitle: "OK")
                alert.show()
            }
}
