I am using LocalNotification in my app. It is working fine but once ApplicationIconBadgeNumber is set, not able to remove it from App. How to remove it?
You need to set the application applicationIconBadgeNumber.
For example in the application didReceiveLocalNotification.
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notif {
application.applicationIconBadgeNumber = notif.applicationIconBadgeNumber-1;
}

I send 10 messages in row to APNS.When application is in background, I receive all of them.
But when Application is in foreground I recieve 8 notifications.
What can be a problem here?
Here is my code which is extremely simple:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
NSLog(#"Test push...");
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound|UIRemoteNotificationTypeNone)];
[self checkForRegisteredUser];
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
return YES;
}
Not sure will this is what you're looking for,
Here is how push notification works,
So when you application is on background, you application will never receive the push notification from the APNs but it will come to your notification tray with the message as they sent it from the server.
But if your application is in the foreground. the method in you app delegate
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
will receive the notification and will perform the necessary action as you have defined in it.
In case if you did not receive the notification you need to check the network connection.
I have developed a similar application like yours and its works well as you are expecting..
I have implemented push notification service in iphone device, but running app will not get the notification service alert message, how to handle the APN service in running app.
Thanks in advance
Just implement in your application delegate
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
and you'll be happy =)
Implement the following code in the delegate method:
(void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification *)notification
{
application.applicationIconBadgeNumber = 0;
NSString *reminderText = [notification.userInfo objectForKey:kRemindMeNotificationDataKey];
}
Also follow the link. It must help you.

I'm making an app that keeps track of some reminders that repeats with an user defined interval.
I've made it so when the alert displays, the action title says "Renew". When you click this, the app opens, and here I want to create the next reminder, but the problem is that I don't know if the app opens because the notification button was tapped or if the notification fired while the app was running.
Anyone got any ideas?
The 'correct' way to do this is to examine your NSApplication's applicationState property in the application:didReceiveRemoteNotification: method of your delegate.
From the documentation for handling local notifications:
iOS Note: In iOS, you can determine whether an application is launched
as a result of the user tapping the action button or whether the
notification was delivered to the already-running application by
examining the application state. In the delegate’s implementation of
the application:didReceiveRemoteNotification: or
application:didReceiveLocalNotification: method, get the value of the
applicationState property and evaluate it. If the value is
UIApplicationStateInactive, the user tapped the action button; if the
value is UIApplicationStateActive, the application was frontmost when
it received the notification.
This is similar to your solution using flags set in applicationWillEnterForeground and applicationDidBecomeActive but with system support.
I don't know if my question was unclear but it seems that I got 4 different answers that all misinterpreted my question :P
However, I discovered that the didReceiveLocalNotivication happens between willEnterForeground and didBecomeActive, so I did this to determine if the app was already open or not:
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
NSLog(#"Opened from notification? %#", wasInactive ? #"yes!" : #"no!");
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
wasInactive = YES;
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
wasInactive = NO;
}
Look up the documentation for UIApplication launch option keys. The last parameter to your application:didFinishLaunchingWithOptions: delegate method contains the information you need.
Also, look at application:didReceiveLocalNotification.
You're looking for
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
or
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
Documentation
If your application is already running you'll get this delegate message on the app delegate
application:didReceiveLocalNotification:
If it wasn't running you'll have to use
application:didFinishLaunchingWithOptions:
You need to respond appropriately in both methods to cover all cases
UPDATED
To detect if the user activated the action button requires a little more complexity. We can tell that application:didFinishLaunchingWithOptions: will have the local notification as a launch option, but it's more difficult with the application:didReceiveLocalNotification:.
Since the application becomes active after the user taps the button, we have to defer until we see that message (or not). Set an NSTimer in application:didReceiveLocalNotification and cancel it in didBecomeActive. That means the user pressed the action button. If the timer isn't cancelled the user was inside the app when it fired.
In your app delegate in this method:
- (BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
You have to examine the launchOptions looking at this key:
UIApplicationLaunchOptionsLocalNotificationKey
When you are already active this will be called:
- (void) application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
Hi there i would like to know which app delegate method get called when my app launch from a push notification (When the app was previously in the background ?)
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
Also check this answer.
Implement the didReceiveLocalNotification: method in your AppDelegate.
- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif {
// Handle the notification here
}
Check the documentation of UIApplicationDelegate
I already use the:
(void)applicationDidEnterBackground:(UIApplication *)application {}
method, but I can't differentiate if is because press the home button or the on/off button.
Thanks in advance,
For the on/off button(or an incoming call or SMS):
- (void)applicationWillResignActive:(UIApplication *)application
For the Home button:
- (void)applicationDidEnterBackground:(UIApplication *)application
With the notification of applicationWillResignActive, applicationDidBecomeActive will still enter while you are entering in background. But there is a way to differentiate by getting the state of the app, so try this in applicationDidEnterBackground.
- (void)appHasGoneInBackground {
bool inBackground = [UIApplication sharedApplication].applicationState == UIApplicationStateBackground;
// lockScreen state
if (!inBackground) {
// do something
}
}
Apple's UIApplication-class reference
Use - (void)applicationDidEnterBackground:(UIApplication *)application {} when your app is entering the background (home button) and - (void)applicationWillTerminate:(UIApplication *)application when it's about to be closed (on/off button or iOS call to close after a random time in background).
My understanding is that when you lock or unlock your iOS device your application delegate will call - (void)applicationWillResignActive:(UIApplication *)application and - (void)applicationDidBecomeActive:(UIApplication *)application, respectively. Locking and unlocking are similar to receiving an interruption like a phone call. Sending your application to the background by hitting the home button calls different methods, namely - (void)applicationDidEnterBackground:(UIApplication *)application and - (void)applicationWillEnterForeground:(UIApplication *)application.
