-(IBAction)switchingbtn:(id)sender
{
    UISwitch *onoff = (UISwitch *) sender;
    UILocalNotification *localNotif = [[UILocalNotification alloc] init];
    if(onoff.on)
    {
        NSLog(@"Shedule notification");


    int tagValue=[sender tag];

    NSMutableDictionary *dict = (NSMutableDictionary *)[alarmsArray objectAtIndex:tagValue];


    NSDate *firedate = [dict objectForKey:@"date"];
    NSLog(@"fire date is %@", firedate);
    localNotif.fireDate = firedate;

    localNotif.alertBody = @"Start Exercise";
    localNotif.applicationIconBadgeNumber = 0;

    // localNotif.timeZone =[NSTimeZone timeZoneForSecondsFromGMT:0];
    localNotif.timeZone = [NSTimeZone systemTimeZone];
    localNotif.repeatInterval = kCFCalendarUnitDay;

      //  [[UIApplication sharedApplication] cancelLocalNotification:localNotif];

        [[UIApplication sharedApplication] cancelAllLocalNotifications];
    NSLog(@"cancel notification");
}

The best way to cancel single notification so far, is to create an notication that has a userInfo dictionary, in this dictionary you could add a notification ID value for an id key. You keep track of the notifications ID (storing in a plist, sql database, etc) and when you need to delete a notification you just need to ask the UIApplication instance for the scheduled notif and filter by the ID, when you find the match you just need to send the cancel method for that notification.
