ios - Pass multiple parameters to addTarget

In my UITableViewCell I have a button. And I want to add action to it by passing multiple parameters in cellForRowAtIndexPath method.

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("CartCell", forIndexPath:
        indexPath) as! CartTableViewCell
    cell.buyButton.addTarget(self, action: self.buyButton(indexPath, 2, 3 ,4 , 5, 6), forControlEvents: .TouchUpInside)
}

May be you can do something like this

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCellWithIdentifier("CartCell", forIndexPath:indexPath) as! CartTableViewCell
    cell.buyButton.tag = (indexPath.section*100)+indexPath.row
    cell.buyButton.addTarget(self, action: "btnBuy_Click:", forControlEvents: .TouchUpInside)
}

func btnBuy_Click(sender: UIButton) {
        //Perform actions here
     let section = sender.tag / 100
     let row = sender.tag % 100
     let indexPath = NSIndexPath(forRow: row, inSection: section)
     self.buyButton(indexPath, 2, 3 ,4 , 5, 6)
}

Create tag value according to you'r requirement and maintaint it's integrity too.
