Reset urbanairship badge count

问题

Problem:

• Let say I get 3 notification.
• It shows the badge count 3 on my app icon.
• I open the app or click on the notification and it clears the badge (All Good so far)
• Now when I get a new notification, the badge count shown on my app icon is 4 instead of 1
• That means that the badge count was not reset on Urbanairship end

My Code so far:

-(void)resetBadgeNotifications:(UIApplication *)application using:(NSDictionary *)notificationInfo{
    if( notificationInfo != nil ){
        [[NSNotificationCenter defaultCenter] postNotificationName:@"newNotification" object:notificationInfo];
    }
    application.applicationIconBadgeNumber=1;
    application.applicationIconBadgeNumber=0;
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
    [application cancelAllLocalNotifications];
    [[UAPush shared] setBadgeNumber:1];//set to 1
    [[UAPush shared] resetBadge];//zero badge
}

I am calling this method from the following three places:

didFinishLaunchingWithOptions

didRegisterForRemoteNotificationsWithDeviceToken

applicationDidBecomeActive

In the last line of my function, I am clearly resetting the badge on UrbanAirship. But it seems to be not working. Can anyone please correct me if I am missing something?

My original answer was for the basic push notifications offered by APNS. I wasn't aware that UrbanAirship have a mechanism to track the badge number for each token. Reading their documentation, it's possible that you forgot to call:

[[UAPush shared] setAutobadgeEnabled:YES]

If your application uses Urban Airship’s autobadge feature, enable client-side autobadge tracking in application:didFinishLaunchingWithOptions: before changing the badge value:

[[UAPush shared] setAutobadgeEnabled:YES]; [[UAPush shared] resetBadge];//zero badge
