I'm Working on PushNotification, I want to manage AppIconBadge no. in IOS.
Badge no is Receiving From parse Site, Suppose Badge no. received from parse id 20. now 20 will show on App logo when the app in background and kill State. i want it show only counting that is Remaining to read in the Notification Center. please help me how can i Manage the App Icon badge no.
App is kill state,one push notification arrived , then Which Function Called by IOS. Can i Control that Function
In kill state you can't access it. You should manage this number from parse before you send the push. to change badge number from the app itself:
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: wantedNumber];
you can handle you badge count in app delegate.m didReceiveRemoteNotification method
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
alert = userInfo[#"aps"][#"alert"];
//Handle you badge count here
}
Badge number comes in payload. You need to increment the badge number at server and keep a track of badge number there itself. On receiving any notification if you open the app the badge count should be reset to any value that you can do # setApplicationIconBadgeNumber.
On app launch reset the counter to 0 or whatever you want at your server thru a network request, so that the next notification send a payload with badge number from 0.

Apps in IOS generally show a badge counter telling how many unread notifications are pending for that app. My understanding is that, to update the badge counter, increment or decrement, we need to send a push notification with the current counter value.
I was testing the behaviour of Gmail app, and even if I mark a message as read on my laptop's browser, the counter on App on IOS got decremented to represent the correct value, without receiving any push notification. I had killed the app on IOS before testing it.
I am wondering how Gmail does that. Can silent push notifications, let us update the app badge counter without showing notification alert? Do silent push notifications work at all, when the app is in killed state?
You can update your app's badge count by sending the new count from the server. For example by sending:
{
“aps” : {
“badge” : 9
}
}
As the payload you would set the badge to 9.
For more on the APNS payload, you can check the docs
On iOS it doesn't matter if the app is killed or not to receive a push notification (btw, that's why they are push notifications). In order to update the badge number, you can send the Background Notification (silent notification), which wakes your app so that your app can update, fetch new content.

I have a task manager app, and I want the app icon to show badges for the number of tasks due today. I know you can use
[UIApplication sharedApplication].applicationIconBadgeNumber=1;
to badge, but the user would have to open the app. I know you can set it up so a notification is sent on a certain date, but all I want is the badge. I don't want a notification with a message sent.
UILocalNotification can be configured to only set the badge of the application, if you leave alertBody as nil, and only fill in the applicationIconBadgeNumber (and fireDate) properties.
I've implmented a simple server for pushing notifications to iOS devices and I can't imagine how to handle badges. I've read some topics and all I know that it's not a good solution to handle them manually on device, that it's the server job...
Everything is clear but I still don't know and couldn't find anywhere how I to let the server know that there are some unreaded notifications on my device? I mean where in UIApplicationDelegate is info about beeing read?
Just to help you guys imagine my problem:
Application is running in foreground and receives push notification.
User doesn't enter app so the badge is visible.
After 5 mins comes another notification (again with badge value set to 1 in payload).
And this scenario could happen many times but the APNS is still pushing payload with the same value for badge.
The number of badges can be obtained from method
[application applicationIconBadgeNumber]
inside application:didFinishLaunchingWithOptions: method.
Hope this helps!
UPDATE:
After clarifying the question, I'll update the answer with accepted solution.
For future searchers:
what if the backend would increase the badge every time when the notification will be sent? for example, You send first notification with badge count 1. Then it's time to send another notification - you send it with badge count 2. Then user opens the app and makes API call to the backend - and you zero-out the badge count, and the next notification would be send with badge count 1. If app get's notification in foreground, it makes the api call immediately and you zero-out the badge count immediately as well.

Update badge with push notification while app in background
(12 answers)
Closed 9 years ago.
I am creating one iOS Application in which I am getting badge number from server, while the application is in foreground, I am updating the badge number in
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
}
but when the application is in background, I have no idea which function I should call.
You may send badge number in push notification like this
{"aps":{"badge":"3","alert":"help","sound":"sound.caf"}}
When the application is in the background didReceiveRemoteNotification method never calls. For doing something when your App is in background you need to implement your logic in AppDelegate's applicationDidEnterBackground: method like.
-(void)applicationDidEnterBackground:(UIApplication *)application
{
[UIApplication sharedApplication].applicationIconBadgeNumber = 2;
}
You can send the badge number from your server itself.
By default when u specify the badge number in your APN payload there is no need to set the badge number of your application. If you didn't receive the badge number from server then you cant do it anyway until the user open the application.
But in ios7 APN had a new feature.
By setting the flag Content-Available:1 will let your application run immediately after received the notification,there you can set your badge number.
Use this
- (void)applicationDidEnterBackground:(UIApplication *)application
{
[UIApplication sharedApplication].applicationIconBadgeNumber = X;
NSLog(#"Application Did Enter Background");
}
Send you badge number in the payload of push notification
I have implemented the APNS in my app. But I have two questions about it.
How to make the badge self-increase? In my app, it is always set to 1 now.
If a push notification arrives when the app is in foreground, as far as I know, I need to implement a altert view and play a sound by my self. In this case, is there any way to play the system default notification sound, i.e. when user change it in settings, it will change automatically.
Thanks.
you can increment the badge count as wasim described but it will only work if you app is in foreground, so for displaying correct badge count your server has to push correct badge number.
for playing default system notification sound when app is in foreground I dont think there is any APIs for that, for that you have put the sound file in your bundle and play that sound when notification receives.
In your AppDelegate.m use the following function:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
badge_value+=[[[userInfo objectForKey:#"aps"] objectForKey:#"badge"]intValue];
[UIApplication sharedApplication].applicationIconBadgeNumber = badge_value;
}
where, badge_value is an integer that stores the badge value.
Usually in all apps, the unread notification counts are maintained in the server. When the server sends a push notification to a particular device token server sends the badge count along with the payload.
Your server logic needs to keep track of the proper badge count and send it appropriately.
{
"aps" :
{
"alert" : "Your notification message",
"badge" : badgecount ,
"sound" : "bingbong.aiff"
}
}
