how to cancel a paticular UILocalNotification in swift?

I have a cell in a table view which has a button for scheduling notifications. Is it possible to delete or cancel a notification for that particular cell without affecting the notifications scheduled by other cells ? I want to delete or cancel the particular notification using the same button. If so, please help me with a sample swift code.

@IBAction func setNotification(sender: UIButton!) {

        cell = tableView.cellForRowAtIndexPath(NSIndexPath(forRow: sender.tag, inSection: 0)) as! CustomTableViewCell
        if sender.selected {

            sender.selected = false
             }else {
currentRegion = CLCircularRegion(center: CLLocationCoordinate2D(latitude: latitude ,longitude:longitude), radius: radius, identifier: identifier)
regionMonitor()
            manager.stopUpdatingLocation()
            sender.selected = true } }

code for didEnterRegion()

func locationManager(manager: CLLocationManager!, didEnterRegion region: CLRegion!) {
            localNotification.regionTriggersOnce = true
            localNotification.alertBody = "you have reached"
            UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
            NSLog("Entering region") }
