I have created a custom `TableViewCell` and currently have a button placed in the cell. When the button is pressed, In the `tableviewcell.swift` file, `IBAction func` gets executed. I cannot figure out how to determine the index path of the cell that the button is in that is pressed. I was trying to use the following

```
    @IBAction func employeeAtLunch(sender: AnyObject) {

    let indexPath = (self.superview as! UITableView).indexPathForCell(self)
    println("indexPath?.row")
}

```

but I get the following error on click:
 `Could not cast value of type 'UITableViewWrapperView' to 'UITableView'`

Any help on how to access the index path of the cell?
