How change the sound name of local notification?

Question

I have an application in which i have button. When i click on button then generate a local notification. The variable of local notification is set in appDelegate file. For generate local notification i used this code:-

UILocalNotification* ln = [[UILocalNotification alloc] init]; ln.alertBody = @"Time for another cup of coffee!"; ln.applicationIconBadgeNumber = 1; ln.fireDate = notification_date; //[NSDate dateWithTimeIntervalSinceNow:15]; ln.timeZone = [NSTimeZone timeZoneWithAbbreviation:@"GMT"]; NSString *string_date=[formatter stringFromDate:notification_date]; NSDateFormatter* formatter_alarm = [[[NSDateFormatter alloc] init] autorelease]; formatter_alarm.timeZone = [NSTimeZone timeZoneWithAbbreviation:@"GMT"]; [formatter_alarm setDateFormat:@"hh:mm a"]; NSString *str=[formatter_alarm stringFromDate:notification_date]; appDelegate.alarm_time=[NSString stringWithFormat:@"%@",str]; NSLog(@"%@",appDelegate.alarm_time);

        [[NSUserDefaults standardUserDefaults] setObject:appDelegate.alarm_time forKey:@"alarm_on_time"];
        [[NSUserDefaults standardUserDefaults] setObject:string_date forKey:@"alarm_on_date"];
         [[NSUserDefaults standardUserDefaults] synchronize]; 
        NSLog(@"alarm will activate on%@",notification_date);
        ln.soundName = @"alarm.wav";
        AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);

        ln.repeatInterval=NSDayCalendarUnit;
        [[UIApplication sharedApplication] scheduleLocalNotification:ln];

// if(appDelegate.appDelegate_notification ==nil) // appDelegate.appDelegate_notification= [[UILocalNotification alloc] init]; appDelegate.appDelegate_notification=ln; [ln release];

Now i have a another button which is used for change the sound of local notification. I wan t that when user click on that button then change the sound of local notification. For that purpose i use this code:-

appDelegate.appDelegate_notification.soundName = @"Blow.wav";

Now problem is that when i click on another button then sound of local notification is not changed. How make that event on button click?

Thanks in advances...

When we generate any local notification then we can set sound file at that time . If we want to set sound after setting notification then i get only one way that i share here. When we edit any sound of alert then first we have to save fire date of alert and after that we will cancel that alert and set a new alert with same fire date anad this time we will pass new sound file. I use this and working fine.
