Come si usa prepareForSegue in swift?

Question

Ho un ViewController con tableview denominato BasicPhrasesVC e voglio passare i dati nella cella selezionata per visualizzarlo sul prossimo ViewController (chiamato BasicPhrasesVC).

class BasicPhrasesVC: UIViewController, UITableViewDataSource, UITableViewDelegate { 

let basicPhrases = ["Hello.","Goodbye.","Yes.","No.","I don't understand.","Please?","Thank you.","I don't know."] 
var selectedBasicPhrase = "" 

func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    return 1 
} 

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


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell")! 
    cell.textLabel?.text = basicPhrases[indexPath.row] 
    return cell 
} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 

Io sono sicuro di cosa mettere qui (voglio passare sulla variabile "selectedBasicPhrase")

} 

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    selectedBasicPhrase = basicPhrases[indexPath.row] 
    performSegueWithIdentifier("BasicPhrasesVC2BasicDisplayVC", sender: self) 

} 
} 

Ogni aiuto è apprezzato.

Answer 1

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    selectedBasicPhrase = basicPhrases[indexPath.row] 
    self.performSegueWithIdentifier("BasicPhrasesVC2BasicDisplayVC", sender: selectedBasicPhrase) 

} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
     if segue.identifier == "BasicPhrasesVC2BasicDisplayVC" { 
      if let nextVC = segue.destinationViewController as? NextViewController { 
       nextVC.selectedBasicPhrase = sender 
      } 
     } 
    }

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) { 
    if (segue.identifier == "<segue name>") { 
     // pass the data 
    } 
} 

Answer 3

Controllare il nome del seguito che prendere destinationViewController e inviare i dati ad esso.

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) { 
    if (segue.identifier == "BasicPhrasesVC2BasicDisplayVC") { 
     let viewController:ViewController = segue!.destinationViewController as ViewController 
     viewController.selectedBasicPhrase = "Test phrase" 
    } 
}
