Apple push notification not changing icon badge automatically

I have seen the mail app in my iPhone (4S, iOS 5.1) automatically updates the badge count if new mail arrives, even when app is not running. So it is possible to achieve this behavior in my app also, right?

My application successfully registers for push notifications for all 3 types - Badge, Alert and Sound. Phone Settings is set ON for all 3 types of remote notifications for this application.

My app receives remote notifications and shows alert, plays sound, but it does not update the badge number. If I launch the app via the View button on the alert, then my app can read the badge value perfectly and I can change/remove/set the icon badge from code.

Any specific reason why iOS cannot change the icon badge of my app automatically when the notification arrives? I have seen all the similar posts, they are all discussing about either phone settings, or about notification types that it registered, or about checking the payload JSON includes badge or not.

Is there any other reason that might cause this problem?

Here is my code blocks:

Register for APNs every time app is launched - 

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];

Device token received almost instantly. Token has been sent to provider, and I am receiving notifications. Alerts and Sounds works. But badge has no automatic effect until I launch the app and change it manually. Please help.

is your badge set to +1 when you send the notification? or just 1? – mkral
Out of curiosity, what are you using push notifications for? – Wug
set it to +1 or however many notifications you need to add. – mkral
Actually it looks like that may only work on urbanairship. Other posts say you need to keep track of notifications server side or send the count to the server. – mkral
@mkral, I will try but apple does not suggest to use +1 developer.apple.com/library/ios/#DOCUMENTATION/… – zinnuree

I also had this exact same problem. The badge icon was not quoted. After many hours of trying to tweak the JSON (after verifying app on phone showed badges, sounds, alerts) - the problem was I had added UIRemoteNotificationTypeNewsstandContentAvailability as one of the alert types my app was registering for. (I went crazy, just picking everything)

So, when UIRemoteNotificationTypeNewsstandContentAvailability is also in the mix, it seems to override the function of allowing aps/badge numbers to update an app icon. (Must be looking to update newsstand info)

The issue is now fixed. The provider server was sending the badge number in quotation marks (as JSON String, i.e. "9"). Strange that APNs/iOS does not recognize it as integer. Now the quotes are removed and it works :)

I had a similar problem, solved it by forcing integer in the badge number (using PHP with data coming from MySQL db):

$body['aps'] = array(
        'alert' => array(
        'action-loc-key'=> utf8_encode($r['button_action']),
        'body'          => utf8_encode($r['message']),
        'launch-image'  => ''
        ),
    'badge' => (int)$r['badge_number'],
    'sound' => 'default'
    );

Ps.: take a look at the utf8_encode command to avoid a json_encode error I faced earlier too.
