Swift : Pass TableViewCell text to new ViewController's cell - ios

Question

How to pass the same text from tableVC to the detail tableVC using an array populated in tableVC.
It is working in tableVC but no data passed into the detailVC.
They share one tableviewcell.
class TableViewCell: UITableViewCell {
#IBOutlet var img: UIImageView!
#IBOutlet var title: UILabel!
}
tableVC
class TableViewController: UITableViewController {
var thecourseName = [String]()
override func viewDidLoad() {
super.viewDidLoad()
thecourseName = ["course 1 ","course 2 ","course 3 "]
theimg = [UIImage(named: "109.png")!,UIImage(named: "110.png")!]
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! TableViewCell
// Configure the cell...
cell.title.text = thecourseName[indexPath.row]
return cell
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if ( segue == "toInfo") {
var text = self.tableView.indexPathForSelectedRow()
var detailsVC: DetalisTableViewController = segue.destinationViewController as! DetalisTableViewController
detailsVC.courseName = thecourseName
}
}
detailVC
import UIKit
class DetalisTableViewController: UITableViewController {
var courseName = [String]()
#IBOutlet var passedCourse: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! TableViewCell
// Configure the cell...
cell.title.text = courseName[indexPath.row]
return cell
}

Your issue is that you're not passing any information to your detailViewController about the contents of the selected cell. Do this instead:
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if ( segue.identifier == "toInfo") {
if let indexPath = tableView.indexPathForCell(sender as! UITableViewCell) {
var detailsVC = segue.destinationViewController as! DetalisTableViewController
println(thecourseName[indexPath.row])
println(indexPath.row)
detailsVC.courseName = thecourseName[indexPath.row]
}
}
}
Now instead of passing the whole array of course names to DetailsTableViewController, your variable courseName just contains one:
var courseName: String = ""
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! TableViewCell
cell.title.text = courseName
return cell
}
