Here's the solution for other visitors:

Using NSKeyedArchiver, I archived my old local notification to one path and when I wanted to remove it, I deleted it from that location.

It's working fine.

Edited :

1)Cache UILocalNotificaiton using NSKeyedArchiver

NSString *archivePath = [self cachePathWithKey:key];
[NSKeyedArchiver archiveRootObject:notification toFile:archivePath];

2) Show Notification

[[UIApplication sharedApplication] scheduleLocalNotification:notification];

3) Remove Notification Whenever you want to remove it.

NSString *archivePath = [self cachePathWithKey:key];

UILocalNotification *cachedNotification = [self notificationForKey:key];
if (cachedNotification == nil) {
    return NO;
}

[[UIApplication sharedApplication] cancelLocalNotification:cachedNotification];

[[NSFileManager defaultManager] removeItemAtPath:archivePath error:nil];

You can use this library also as I've used that one only.

Copy LocalNotificationHelper Folder in your project and User removeNotificationForKey and showNotification methods.
