I'm using Urban Airship to send push notifications to my app
eg:
{"aps": {"badge": 2, "alert": "Part 2 of the August Issue is ready to download!", "sound": "default"}, "device_tokens": ["X"]}
The alert will display perfectly, however the app icon is never badged regardless of what I set "badge":# to...
Is my payload incorrect or is there extra code I'm supposed to add to my app to handle badges as well as alerts? Thanks!
EDIT:
I'm registering for push notifications like this:
// Register for notifications
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeNewsstandContentAvailability | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert)];
I was running with a similar problem. After a few minutes of checking around. I notice that there was a problem with my server side code. I found out that badge value has to be implicitly set as an integer to get the desired result. Hope that helps anyone reading this.
set the following code in the appdelegate .m file..
-(void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
NSLog(#"Received notification: %#", userInfo);
//[self addMessageFromRemoteNotification:userInfo];
NSString* alertValue = [[userInfo valueForKey:#"aps"] valueForKey:#"badge"];
NSLog(#"my message-- %#",alertValue);
int badgeValue= [alertValue intValue];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeValue];
}
In iOS 5 there is a Settings -> Notifications. Double check that the Badge App Icon is turned on.
I assume that the app is not in the foreground when you were testing? It if is in the foreground then you have to handle badging manually.

Is there a way to update the number in the badge without showing an alert or opening the app?
I am writing an app that should always display the current number of unread messages in the icon badge, but I want to do so without displaying any alerts to the user.
I am developing for iOS 5.0+.
EDIT: To be more clear, I am asking about a way to do this when the app is not running. I want the server to push a new badge number without showing an alert.. Is this possible?
You can do it.
It is possible to send a push notification without an alert.
You can even register your application just to badge notifications, in which case the provider server won't even be able to send alerts or sounds.
The Notification Payload
Each push notification carries with it a payload. The payload
specifies how users are to be alerted to the data waiting to be
downloaded to the client application. The maximum size allowed for a
notification payload is 256 bytes; Apple Push Notification Service
refuses any notification that exceeds this limit. Remember that
delivery of notifications is “best effort” and is not guaranteed.
For each notification, providers must compose a JSON dictionary object
that strictly adheres to RFC 4627. This dictionary must contain
another dictionary identified by the key aps. The aps dictionary
contains one or more properties that specify the following actions:
An alert message to display to the user
A number to badge the application icon with
A sound to play
Note that it says one or more of the properties. The alert property is optional. You can even send a notification with an empty aps dictionary (i.e. send only custom properties).
Example 5. The following example shows an empty aps dictionary;
because the badge property is missing, any current badge number shown
on the application icon is removed. The acme2 custom property is an
array of two integers.
{
"aps" : {
},
"acme2" : [ 5, 8 ]
}
The only alert the user will see it the alert that asks him/her whether to allow push notifications. That alert will only be displayed the first time the app is launched after installation.
In this example you register to non alert notifications (badges and sounds only) :
Listing 2-3 Registering for remote notifications
- (void)applicationDidFinishLaunching:(UIApplication *)app {
// other setup tasks here....
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
}
// Delegation methods
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken {
const void *devTokenBytes = [devToken bytes];
self.registered = YES;
[self sendProviderDeviceToken:devTokenBytes]; // custom method
}
- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
NSLog(#"Error in registration. Error: %#", err);
}
All quotes are taken from the Apple Local and Push notifications programming guide.
you should use applicationIconBadgeNumber for locally handling your app badge number
[UIApplication sharedApplication].applicationIconBadgeNumber = number_of_notifications;
I don't think it is possible to do without alert as far as adding badge counter from remote notification. You should read about APN Service, in your case you might register for UIRemoteNotificationTypeBadge you should read about Local & Push Notification Programming guide
You can use
[UIApplication sharedApplication].applicationIconBadgeNumber = aNumber;
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
use this method....this will help u.
I am working on push notification in iphone. when i receive push notification, its showing 1 on my application icon, next time its 2,3,4. if i open application its 0. Next time its should be 1,2,3,4... but its showing last number and +1. i want reset push notification badge after open application. i am sending +1 from urban airship.
and its not working for me.
[[UIApplication sharedApplication] cancelAllLocalNotifications];
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
I use this code in my app because the Urban Airship (UA) documentation said to
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
[[UAPush shared] resetBadge];
but it doesn't work, the badge on the app icon keeps incrementing. I saw a few posts on this very issue on UA's forums and they haven't given a clear answer.
EDIT #1:
I received the following response from a support technician at UA with the following suggestions, which worked great:
What you want to do, is ensure that in your didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method, you are calling the following:
[[UAPush shared] setAutobadgeEnabled:YES];
[[UAPush shared] resetBadge];//zero badge on startup
and also call [[UAPush shared] resetBadge]; in the following methods as well:
applicationDidBecomeActive:(UIApplication *)application
and
didReceiveRemoteNotification:(NSDictionary *)userInfo
The technician also mentioned that assigning 0 to applicationIconBadgeNumber is not necessary, so I took it out. Still works beautifully.
EDIT #2:
I ended up having to modify application:didReceiveRemoteNotification: to include a call to UA's handleNotification:applicationState: method:
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
// Get application state for iOS4.x+ devices, otherwise assume active
UIApplicationState appState = UIApplicationStateActive;
if ([application respondsToSelector:#selector(applicationState)])
{
appState = application.applicationState;
}
[[UAPush shared] handleNotification:userInfo applicationState:appState];
[[UAPush shared] resetBadge];
}
because I was having a problem with the following scenario:
User is in app
Push notification received
No badge was displayed on app icon when returning to home screen (as expected)
Another push notification is received
Badge displayed number greater than 1
With the modification above, this scenario is handled. I guess you have to tell UA that the notification is handled when one is received and the app is running in the foreground.
I have used Urban Airship and have had this problem before. You are not showing the code but i am assuming that when a notification is received, you are setting the application badge number to what urban airship is passing to you, don't do that. Just let the application self handle this, when a remote notification comes in, let it auto increment on its own. If that is not the case it could be that, on the urban airship side, you are setting a badge number to send with the push. Do not send a badge number with the push notification, leave that part out, iOS should auto increment your badge from its current badge number.
Similar to this question: How do I access remote push notification data on applicationDidBecomeActive?
But the different is how can you access the notification data when you are inapplicationDidBecomeActive and if you have clicked on the app icon instead of the push notification.
The flow is: If you click on the push notification then didReceiveRemoteNotification will be triggered, but if you click on the original app icon, only applicationDidBecomeActive will be triggered and didReceiveRemoteNotification will not be called.
I am looking for the later case so how can I access the push notification data.
(Both case assuming the app is in background and not killed yet.)
You can't get remote push payload by launching app from homescreen.
If the push data is important for app use, load it from your server after app launched.
#fannheyward answer is absolutely correct. You cannot get payload when application is launched by tapping app icon.
I have an idea, what if you get to know that some notification is pending when app is launched by tapping app icon. With this knowledge your app can fetch payload from your server.
You can set "Badge" in every such notification and on applicationDidBecomeActive you can check [application applicationIconBadgeNumber] > 0 to know that some notification is active. After fetching payload from your server you can set it to 0 like below
[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
Please note: This means your app will have badge displayed over it when notification is received. I am not sure of the behaviour when badge is disabled by user from settings.
If your application target is over iOS7, you can do only if application is alive in backgroud.
In the capabilities settings at Xcode, you should enable Background Modes>Remote notifications, and write below code.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
// save userInfo in NSUserDefaults
completionHandler( UIBackgroundFetchResultNoData );
}
If you want to test it, it will be helpful to use https://github.com/acoomans/SimulatorRemoteNotifications
From the server side, make sure to set content-available property with a value of 1
For this to work I also had to check the background fetch box.
You should get the notification in the launchWithOptions method in your appDelegate something like this:
NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
if(remoteNotif != nil){
//Handle your notification
}
I have searched for this, and I can't find any documentation about doing these banner / notification / alerts... but I would really like to implement it.
In case my description in words is not clear, here is a picture of what I would like to do:
1:
I tried using this code:
UILocalNotification *note = [[UILocalNotification alloc] init];
[note setAlertBody:[NSString stringWithFormat:#"%# scanned", result]];
[note setAlertAction:#"New Scanned Image"];
[[UIApplication sharedApplication] presentLocalNotificationNow:note];
And it worked fine, such that it displayed the notification in the notifications center, but there was no banner alert.
So what are the classes that I use for this?
Thanks!
You can't define what type of alert to be used for your app's notifications. It can be set only by user through Notification Center settings.
Note! Alerts appear only when you app is closed or it is in background. If your app is active (it is in foreground), it will get only a notification (see - (void)applicationDidReceiveMemoryWarning: for details).
I have a GPS app that registers to run in the background. I also show a UILocalNotification when I have finished a process. This correctly shows, and if the app is open, then it also appears in Notification Center (swipe down from top). But, if I call the UILocalNotification when my app is in the background, or the screen is locked, I DO get the notification, but it does NOT show up in Notification Center.
I am correctly registering for notifications in my app delegate (iOS 5 bug workaround):
// Register for notifications
[[UIApplication sharedApplication]registerForRemoteNotificationTypes:
UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeSound];
Calling the notification:
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
localNotif.alertBody = msg;
localNotif.alertAction = NSLocalizedString(#"View", nil);
localNotif.soundName = #"alert.caf";
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
[[UIApplication sharedApplication] presentLocalNotificationNow:localNotif];
[localNotif release];
Is this a bug? Why would it show up in Notification Center only when my app is open, even though the notification is shown to the user, and not other times?
Are you also using push notifications? I believe there is no need to call registerForRemoteNotificationTypes: if you are only using local.
Check Here
From the look of the code you posted, it does not look like the code would run in the background. It looks like you are trying to present a Local Notification when an even occurs in the background. You can not do this. Local Notifications are meant to be scheduled while the app is running to go off at a later time when the app is not running, and then they will trigger even when the app is closed.
You need to use Push Notifications. Check out Apple's documentation here.
EDIT: Is your app enabled for the notification center in settings?
have you added the UIBackgroundModes key to your Info.plist file ?
You need to have the UIBackgroundModes Key set to location.
