create tableview inside tableviewcell using swift - xcode

Question

well i create tableview and inside of it tableview cell with xib file
now i want create tableview inside xib file , the main problem is that u can't create cell inside of it to define the identifier for this cell
i keep get this error
'unable to dequeue a cell with identifier AutoCompleteRowIdentifier -
must register a nib or a class for the identifier or connect a
prototype cell in a storyboard'
this is my code
import UIKit
class TableViewCell2: UITableViewCell, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate {
#IBOutlet weak var textField: UITextField!
#IBOutlet weak var autocompleteTableView: UITableView!
var pastUrls = ["Men", "Women", "Cats", "Dogs", "Children"]
var autocompleteUrls = [String]()
func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool
{
autocompleteTableView.hidden = false
let substring = (textField.text! as NSString).stringByReplacingCharactersInRange(range, withString: string)
searchAutocompleteEntriesWithSubstring(substring)
return true // not sure about this - could be false
}
func searchAutocompleteEntriesWithSubstring(substring: String)
{
autocompleteUrls.removeAll(keepCapacity: false)
for curString in pastUrls
{
var myString:NSString! = curString as NSString
var substringRange :NSRange! = myString.rangeOfString(substring)
if (substringRange.location == 0)
{
autocompleteUrls.append(curString)
}
}
autocompleteTableView.reloadData()
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return autocompleteUrls.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let autoCompleteRowIdentifier = "AutoCompleteRowIdentifier"
let cell : UITableViewCell = tableView.dequeueReusableCellWithIdentifier(autoCompleteRowIdentifier, forIndexPath: indexPath) as UITableViewCell
let index = indexPath.row as Int
cell.textLabel!.text = autocompleteUrls[index]
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let selectedCell : UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)!
textField.text = selectedCell.textLabel!.text
}
override func awakeFromNib() {
super.awakeFromNib()
textField.delegate = self
autocompleteTableView.delegate = self
autocompleteTableView.dataSource = self
autocompleteTableView.scrollEnabled = true
autocompleteTableView.hidden = true
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}}
as you know you can't define identifier inside xib file
thanks

You need to register a cell with autocompleteTableView before you can dequeue it. Modify your code like this:
override func awakeFromNib() {
super.awakeFromNib()
textField.delegate = self
autocompleteTableView.delegate = self
autocompleteTableView.dataSource = self
autocompleteTableView.scrollEnabled = true
autocompleteTableView.hidden = true
// Register cell
autocompleteTableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "AutoCompleteRowIdentifier")
}
