Come risolvere l'errore: questa classe non è conforme al codice di codifica per la chiave tabellaView. '

Question

Ho creato un'app con Table View e Segmented Control e questa è la mia prima volta. Sto usando un po 'di codice e alcuni tutorial, ma non funziona. Quando eseguo la mia app E 'crash e sta mostrando questo errore nei log:

Il codice che ho usato è:

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate { 

let foodList:[String] = ["Bread", "Meat", "Pizza", "Other"] 
let drinkList:[String] = ["Water", "Soda", "Juice", "Other"] 

@IBOutlet weak var mySegmentedControl: UISegmentedControl! 
@IBOutlet weak var myTableView: UITableView! 

override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view. 
} 

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 

    var returnValue = 0 

    switch(mySegmentedControl.selectedSegmentIndex) { 
    case 0: 
     returnValue = foodList.count 
     break 
    case 1: 
     returnValue = drinkList.count 
     break 
    default: 
     break 
    } 

    return returnValue 
} 

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    let myCell = tableView.dequeueReusableCellWithIdentifier("myCells", forIndexPath: indexPath) 

    switch(mySegmentedControl.selectedSegmentIndex) { 
    case 0: 
     myCell.textLabel!.text = foodList[indexPath.row] 
     break 
    case 1: 
     myCell.textLabel!.text = drinkList[indexPath.row] 
     break 
    default: 
     break 
    } 

    return myCell 
} 

@IBAction func segmentedControlActionChanged(sender: AnyObject) { 
    myTableView.reloadData() 
} 

Ecco main.Storyboard

Ho controllato il codice molte volte, ma non funziona. Per prima cosa ho dovuto usare solo Table View, guardando questo tutorial (https://www.youtube.com/watch?v=ABVLSF3Vqdg), ho pensato che funzionasse per usare Segmented Control come nell'esercitazione. Ma ancora non funziona. Stesso codice, stesso errore. Qualcuno può aiutarmi?

Answer 1

Lo storyboard è impostato per prevedere una presa denominata tableView ma il nome della presa effettiva è myTableView.

Se si elimina la connessione nello storyboard e si ricollega al nome della variabile corretta, è necessario risolvere il problema.

Answer 2

Qualche possibilità che abbia cambiato il nome della vista tabella da "TableView" a "myTableView" ad un certo punto?
