Swift- passing data from a multiple-section tableview to ViewController - ios

Question

I have a two-section tableview (see image below)
When I click row "A", another tableview shows up with letter "A"
When I click row "B", another tableview shows up with letter "B"
How can I pass the letter "C" to another tableview when I click row C ?
Here's my code in TableView:
import UIKit
class manhinh1: UITableViewController {
var UserDefault:NSUserDefaults!
var array:[[String]]!
override func viewDidLoad() {
super.viewDidLoad()
UserDefault = NSUserDefaults()
array = [["A","B"],["C","D","E"]]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Potentially incomplete method implementation.
// Return the number of sections.
return array.count
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete method implementation.
// Return the number of rows in the section.
if section == 0 {
return array[0].count
}
if section == 1 {
return array[1].count
}
return 1
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! UITableViewCell
if indexPath.section == 0 {
cell.textLabel?.text = array[0][indexPath.row]
}
if indexPath.section == 1 {
cell.textLabel?.text = array[1][indexPath.row]
}
// Configure the cell...
return cell
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
var row = self.tableView.indexPathForSelectedRow()!.row
UserDefault.setObject(array[0][row], forKey: "selected")
}
}
Here's the code in second view:
import UIKit
class ViewController: UIViewController {
var UserDefault:NSUserDefaults!
#IBOutlet weak var lbldata: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
UserDefault = NSUserDefaults()
// Do any additional setup after loading the view, typically from a }
lbldata.text = UserDefault.objectForKey("selected") as! String
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
I did try a few code in prepareForSegue, but it didn't work. I hope you guys can show me a way. Thanks

You have to get the row and the section to access your multidimensional array. Then get the destination view controller of your segue and assign the corresponding value from the array to the UserDefault property:
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
var row = self.tableView.indexPathForSelectedRow()!.row
var section = self.tableView.indexPathForSelectedRow()!.section
var destinationViewController = segue.destinationViewController as! ViewController
destinationViewController.UserDefault.setObject(array[section][row], forKey: "selected")
}
