Segue-Fehler "Ambigious Referenz zu Mitglied 'tableView'" Swift

Question

Ich bekomme diesen Fehler in der Vorbereitung für die Funktion "segue", wenn ich meinem View Controller einen Abschnitt hinzufügen möchte. Dies ist der Fehler: "Ambigious Reference to member ' Tableview‘"

Hier ist mein Code:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) { 
    if segue.identifier == "showCountryDetails" { 
    if let indexPath = self.tableView.indexPathForSelectedRow() { 
    let destinationController = segue.destinationViewController as! 
    DetailViewController 
    destinationController.countryImage = self.photos[indexPath.row] 
    } } 
} 

TravelTableViewController.swift

import UIKit 

class TravelTableViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { 

    var countries = ["Qatar","Brazil","United Kindgom","KSA"] 
    var cities = ["Doha","Rio","London","Riyadh"] 
    var photos = ["Qatar.jpg","Rio.jpg","Lndn.jpg","KSA.png"] 

    var countryIsVisited = [Bool](count: 4, repeatedValue: false) 
    var countryIsNotVisited = [Bool](count: 4, repeatedValue: false) 




    override func viewDidLoad() { 
     super.viewDidLoad() 

     // Do any additional setup after loading the view. 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     return countries.count 
    } 

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
     let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath:indexPath) as!TravelTableViewCell 

     cell.CityLabel.text = cities[indexPath.row] 
     cell.CountryLabel.text = countries[indexPath.row] 
     cell.ImageLabel.image = UIImage(named: photos[indexPath.row]) 

     cell.ImageLabel.layer.cornerRadius = cell.ImageLabel.frame.size.width/2 
     cell.ImageLabel.clipsToBounds = true 

     if countryIsVisited[indexPath.row] { 
      cell.accessoryType = .Checkmark 
     } 

     else{

Answer 1

machen, wo die Verbindungs ​​Outlet zu Ihrem tableView ist? Scheint, dass Ihr Code es nicht hat. Control-Drag von Storyboard (wenn Sie sie verwenden) und Ihr Fehler sollte weggehen.

Answer 2

indexPathForSelectedRow ist eine Eigenschaft, keine Methode, entfernen Sie die Klammern

if let indexPath = self.tableView.indexPathForSelectedRow { 

Answer 3

Nur UIViewController-UITableViewController in Ihrer Klassendefinition ändern.

Dies wird die self.tableView verfügbar
