Stop Repeating Local Notification iOS - ios

Question

I have initialize local notification for every 30 seconds. and i want to stop repeating it once user has pressed button for stop Local Notification.
problem is i couldnt find a way of doing it. it keeps repeating every 30 seconds
This is how i have sheducled localnotification
// Schedule the notification
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:30];
localNotification.alertBody = #"Testing Repeating Local Notification";
localNotification.applicationIconBadgeNumber = 1;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.repeatCalendar = [NSCalendar currentCalendar];
localNotification.repeatInterval = kCFCalendarUnitSecond;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
I have tried [[UIApplication sharedApplication] cancelAllLocalNotifications]; . but it dosent work.

Answer 1

Can you set repeatInterval to 0. According to documentation if it is set to zero notification will be fired once. So when stop button is pressed you can do following
localNotification.repeatInterval = 0;
[[UIApplication sharedApplication] cancelAllLocalNotifications];

Answer 2

I solved it.
just removed localNotification.repeatCalendar = [NSCalendar currentCalendar]; from above code.

Answer 3

you can remove notification when you get notification in application active state.
just like
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
if (application.applicationState == UIApplicationStateActive)
{
NSLog(#"Application is active");
/*
...
do some process
...
*/
//remove notification
[application cancelLocalNotification:notification];
}
else
{
NSLog(#"Application is inactive");
}
}
