Sample code for canceling the local notification.
I am having a application which sets a local notification and now i want to cancel one of the local notification set the by the application can someone provide the sample code for the same
Cancel all local notifications with this code:
[[UIApplication sharedApplication] cancelAllLocalNotifications];
(you actually just need the middle line.
Cancel one local notification with this line of code:
[[UIApplication sharedApplication] cancelLocalNotification:theNotification];
where theNotification is a UILocalNotification object, so in order to cancel a specific notification you need to hold on to it's UILocalNotification.
You can find more stuff in apple's documentation: http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/IPhoneOSClientImp/IPhoneOSClientImp.html

I am developing game which have support of server side push notification of score and winning notification, User game request.
All is working fine with notification read and response store to device side. But when notification is pushing to notification center. when i click on notification at that time it remove all the push notification from notification center with following code:
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
But i want to remove selected remote notification from notification center.
Is there any way to remove single remote notification.Please help me.
Thanks in advance.
To cancel local notifications
If you have the means to obtain a reference to the specific UILocalNotification instance you want to cancel, you can call cancelLocalNotification: on it.
Try traversing all scheduled notifications in order to obtain that reference by going through:
NSArray *scheduledNotifications = [[UIApplication sharedApplication] scheduledLocalNotifications];
To cancel remote notifications
This is entirely up to the server, can't be done without proper API on the server's side.
I want to cancel all local notifications when app deleted from background, not from Device.
I know this is
[[UIApplication sharedApplication] cancelAllLocalNotifications];
but my Question is where should i pass it to fire event when application terminates from background.
I called inside applicationWillTerminateFromBackground but it is not working.
You could simply check to see if the app is in the background, and if it is, not fire the notifications.
in my app I am using local notifications and often they have a repeat interval set.
The problem is, when the user deletes the app and reinstalls it, the repeat notifications start firing again.
Is there a fix for this problem? Will the following suggestion from another user work? :
you can use [[UIApplication sharedApplication] cancelAllLocalNotifications]; only at first launch, so that "old" notification will be cancelled....(I haven't tried that)
Thanks a lot!
you can use [[UIApplication sharedApplication]
cancelAllLocalNotifications]; only at first launch, so that "old"
notification will be cancelled...
This is not your solution. This will cancel all your already scheduled notification every time when your didFinishLaunching method will called. So before applying above solution there should be one more check. Store a value in NSUserDefauls for checking that you are installing application again after deleting.
if(![[NSUserDefaults standardUserDefaults]objectForKey:#"Notification"]){
[[UIApplication sharedApplication] cancelAllLocalNotifications]
[[NSUserDefaults standardUserDefaults]setBool:Yes ForKey:#"Notification"];
}
This will prevent from canceling all notifications every time.
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.
there is the possibility of a LocalNotification on the iPhone to load on a date?
My problem is that I create an event for the notification but i release the object after creation.
Or can I just create a new Object with the same data to delete my Notification?
sorry for my english...
scheduledLocalNotifications will give you the list of all scheduled notifications and use
- (void)cancelLocalNotification:(UILocalNotification *)notification
or you can cancel them all using:
[[UIApplication sharedApplication] cancelAllLocalNotifications];
