title: delete tableViewCell on long press
body: <p>I currently have a sidebar menu in an iOS 9.2 app running on Xcode 7.2 written in Swift 2 that allows the user what data to load to populate the view. I'm using SWRevealViewController to create that sidebar. I have a container view controller which has the front page and the sidebar page listing all the options the user has. Each time the user selects a cell from the sidebar table, it performs a segue that allows the front page to be refreshed. What I want to do is to allow the user to delete a cell from the table with a long press. I'd like to show an AlertViewController to confirm the user's decision, and if "Yes" is selected, I want to delete the cell, and select the very first item in the table. I've tried following the instructions from <a href="https://stackoverflow.com/questions/3924446/long-press-on-uitableview">Long press on UITableView</a>
  but I keep getting the error "unrecognized selector sent to instance"</p>
  
  <p>Here's the code that I'm using for setting up the gestureRecognizer in the cellForRowAtIndexPath function:</p>
  
  <pre><code>override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -&gt; UITableViewCell {
      let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell;
      cell.textLabel!.text = tableArray[indexPath.row];
      let holdToDelete = UILongPressGestureRecognizer(target: cell, action: "longPressDelete");
      holdToDelete.minimumPressDuration = 1.00;
      cell.addGestureRecognizer(holdToDelete);
      return cell;
  }
  </code></pre>
  
  <p>And here's the longPressDelete function: </p>
  
  <pre><code>func longPressDelete(sender: UILongPressGestureRecognizer) {
      let alert: UIAlertController = UIAlertController(title: "Please Confirm", message: "Are you sure you want to delete this car from your database?", preferredStyle: .Alert);
      alert.addAction(UIAlertAction(title: "Yes", style: .Destructive, handler: { (UIAlertAction) -&gt; Void in
          if let tv = self.tableView {
              let point: CGPoint = sender.locationInView(self.tableView);
              let indexPath: NSIndexPath = self.tableView.indexPathForRowAtPoint(point)!;
              tv.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade);
              NSUserDefaults.standardUserDefaults().removeObjectForKey("fillUp" + tableArray[indexPath.row]);
              NSUserDefaults.standardUserDefaults().removeObjectForKey("services" + tableArray[indexPath.row]);
              tableArray.removeAtIndex(indexPath.row);
              NSUserDefaults.standardUserDefaults().setObject(tableArray, forKey: "cars");
              self.deleted = true;
              self.performSegueWithIdentifier("tableToDashboard", sender: self);
  
          }
      }));
      alert.addAction(UIAlertAction(title: "No", style: .Default, handler: nil));
      self.presentViewController(alert, animated: true, completion: nil);
  }
  </code></pre>
  
  <p>Here's the prepareForSegue function: </p>
  
  <pre><code>override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
      if (deleted) {
          let indexPath: NSIndexPath = NSIndexPath(forRow: 0, inSection: 0);
          fillUpKey = "fillUp" + tableArray[indexPath.row];
          servicesKey = "services" + tableArray[indexPath.row];
          localFillUpArray = [fillUp]();
      } else {
          let indexPath: NSIndexPath = self.tableView.indexPathForSelectedRow!;
          fillUpKey = "fillUp" + tableArray[indexPath.row];
          servicesKey = "services" + tableArray[indexPath.row];
          localFillUpArray = [fillUp]();
      }
  }
  </code></pre>
  
  <p>What I'd like to happen is that the user deletes the item in the cell, and the app then performs a segue to the front screen after loading the information from another source. Thanks for taking the time to read this and possibly provide an answer. I hope I haven't made a rookie mistake somewhere.</p>
