AppDelegate错误

Question

我想我已经发布了一些关于这个问题的帖子，直到现在我尝试创建一个表视图时，这个问题才几乎没有发生！

代码如下：

import UIKit

class ViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell

        {
            var cell = tableView.dequeueReusableCellWithIdentifier("myCell", forIndexPath:indexPath) as UITableViewCell
            cell.textLabel.text = "Cell number \(indexPath.row)"
            return cell
        }
    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
    {
        return 11 
    }


}

顺便说一下，我使用的是-> 6.1，使用的是swift编程语言！

编辑信号错误是'Thread1: SIGABRT‘

Answer 1

尝试为表视图委托实现numberOfSections，它可能会崩溃，因为缺少该委托。

Answer 2

您应该做的是使用IB从对象库中拖动一个Table View Controller，然后将Class属性设置为您的UITableViewController子类。

如果您只是将IB中常规视图控制器的类更改为UITableViewController子类，它将不会为您创建表视图。
