ios - Swift - TableView 未填充数据但未显示任何错误

Question

使用以下教程，我尝试显示一些将填充在表格中的股票信息。我已经创建了 TableView Controller 和 TableView 单元格，并将 stockTableViewCell 与 TableView 单元格链接起来。但是，我无法将主 Storyboard 上的表格 View 与自定义表格 View Controller 链接起来。

基本上，每次我尝试将其输入自定义类字段时，它都不适用，当我离开时，它就会消失

我的问题是，我的 View Controller 或 TableView 单元格是否有问题，或者我的 Storyboard中是否存在我配置错误的内容？

表格 View Controller

import UIKit

class stocksTableViewController: UITableViewController{

    // Mark: Properties

    var stocks = [stockData]()
    let stock = stockinfo()

    override func viewDidLoad() {
        super.viewDidLoad()
        loadSampleStockData()

    }

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

    func loadSampleStockData () {

        var stock1: stockData = stockData(name: "", askPrice: "", percentageChange: "", stockTicker: "")
        var stock2: stockData = stockData(name: "", askPrice: "", percentageChange: "", stockTicker: "")
        var stock3: stockData = stockData(name: "", askPrice: "", percentageChange: "", stockTicker: "")

        stock.getInfo("FB") {(name, price, change) in dispatch_async(dispatch_get_main_queue(),{
            stock1 = stockData(name: name, askPrice: price, percentageChange: change, stockTicker: "FB")})
        }

        stock.getInfo("MSFT") {(name, price, change) in dispatch_async(dispatch_get_main_queue(),{
            stock2 = stockData(name: name, askPrice: price, percentageChange: change, stockTicker: "MSFT")})
        }

        stock.getInfo("APPL") {(name, price, change) in dispatch_async(dispatch_get_main_queue(),{
            stock3 = stockData(name: name, askPrice: price, percentageChange: change, stockTicker: "APPL")})
        }

        stocks += [stock1, stock2, stock3]
    }

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

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

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cellIdentifier = "stockViewCell"

        let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! stockTableViewCell

        let stock = stocks[indexPath.row]

        cell.stockName.text = stock.name
        cell.stockPercentage.text = stock.percentageChange
        cell.stockDollarChange.text = stock.askPrice
        cell.stockTicker.text = stock.stockTicker

        return cell
    }
}

表格 View 单元格

import Foundation
import UIKit

class stockTableViewCell: UITableViewCell {

    // Properties

    @IBOutlet weak var stockTicker: UILabel!
    @IBOutlet weak var stockPercentage: UILabel!
    @IBOutlet weak var stockName: UILabel!
    @IBOutlet weak var stockDollarChange: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization Code
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)
        // Configure the view for the selected state
    }
}

您实际上需要在 viewDidLoad() 中注册自定义的tableviewcell
