Add a picker view at the footer of the app - ios

Question

I would like to add a picker view at the footer of the app when I tap the cell and change the Detail label with the picker view data. I would like to do the same think with the DatePicker, but only in one cell ( the one named Service appt. Date).
This is my code:
import UIKit
class Service2Appointment: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var TableView: UITableView!
#IBOutlet weak var pickerView: UIPickerView!
let FormName = ["State","City","Vehicle Reg Number","Location","Current Kms","Service appt. Date","Service appt. Type","Pick-up Vehicle","Discount Code","Service Notes"]
let textCellIdentifier = "TextCell"
override func viewDidLoad() {
super.viewDidLoad()
pickerView.hidden = true
TableView.delegate = self
TableView.dataSource = self
self.TableView.rowHeight = 70
TableView.backgroundView = UIImageView(image: UIImage(named: "background.png"))
self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: UITextFieldDelegate Methods
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return FormName.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = TableView.dequeueReusableCellWithIdentifier(FormName[indexPath.row], forIndexPath: indexPath) as! UITableViewCell
if (indexPath.row % 2 == 0) {
cell.backgroundColor = UIColor.clearColor()
}else{
cell.backgroundColor = UIColor.clearColor()
cell.textLabel?.backgroundColor = UIColor.whiteColor().colorWithAlphaComponent(0.0)
}
let row = indexPath.row
cell.detailTextLabel?.text = FormName[row]
cell.textLabel?.text = FormName[row]
cell.textLabel?.textColor = UIColor.whiteColor()
return cell
}
// MARK: UITableViewDelegate Methods
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
TableView.deselectRowAtIndexPath(indexPath, animated: true)
let row = indexPath.row
println(FormName[row])
}
}
