如何快速使用prepareForSegue？

我有一个带有名为 BasicPhrasesVC 的表视图的 ViewController，我想传递所选单元格中的数据以将其显示在下一个 ViewController（称为 BasicPhrasesVC）上。

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?) {

我不确定要放在这里的内容（我想传递变量“selectedBasicPhrase”）

}

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

}
}

任何帮助表示赞赏。

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
            }
        }
    }
