Swift tableview in popover doesn't show data - ios

Question

I am trying to setup a popover view containing a textfield and a tableview, but I couldn't make the tableview to show the data. It would be much appreciated if you could help me on this.
On the main ViewController, I put a label to trigger the segue of popover,
import UIKit
class ViewController: UIViewController, UIPopoverPresentationControllerDelegate {
#IBOutlet weak var textField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func popover(sender: AnyObject) {
self.performSegueWithIdentifier("ShowDetails", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "ShowDetails" {
if let controller = segue.destinationViewController as? UIViewController {
controller.popoverPresentationController!.delegate = self
controller.preferredContentSize = CGSize(width: 320, height: 50)
}
}
}
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
return .None
}
}
A PopoverCell is setup for the prototype cell,
import UIKit
class PopoverCellTableViewCell: UITableViewCell {
#IBOutlet weak var AreaCellLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
A PopoverControllerView is set for the popover itself.
import UIKit
class PopoverViewController: UIViewController, UITextFieldDelegate, UITableViewDataSource, UITableViewDelegate {
var areas = [Area]()
// #IBOutlet weak var NewArea: UITextField!
// #IBOutlet weak var SaveNewArea: UIButton!
#IBOutlet weak var subtableView: UITableView!
override func viewDidLoad() {
subtableView.dataSource = self
subtableView.delegate = self
super.viewDidLoad()
LoadsampleArea()
// Do any additional setup after loading the view.
}
func LoadsampleArea () {
let area1 = Area(AreaName:"Moountain")!
let area2 = Area(AreaName:"ByHill")!
let area3 = Area(AreaName:"Yard")!
areas += [area1, area2, area3]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return areas.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
// Table view cells are reused and should be dequeued using a cell identifier.
let cellIdentifier = "AreaCell"
let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! PopoverCellTableViewCell
let area = areas[indexPath.row]
cell.AreaCellLabel.text = area.AreaName
dismissViewControllerAnimated(true, completion:nil)
return cell
}
}
and a simple data file to put the data.
import UIKit
class Area {
var AreaName: String
init? (AreaName: String) {
self.AreaName = AreaName
if AreaName.isEmpty {
return nil
}
}
}

Where is your UITableView object in your PopoverViewController class ? I can't see any reference to it.
Maybe your didn't copy-paste it since the textfield is commented too, in this case I'll suggest to check if the delegate an datasource are set property.
