在Swift中以编程方式创建一个UITableViewController [英] create a UITableViewController programmatically in Swift

问题描述

正如标题所说，我试图以编程方式设置UITableViewController。经过几个小时的尝试，我希望有人可以帮助我。并且，是的，我已经检查过此事的其他帖子：

I'm trying to, as the title say, set up a UITableViewController programmatically. After a few hours of trying I hope someone can help me. And, yes, I hve checked out other posts on this matter:

import UIKit

class MainViewController: UITableViewController {

    init(style: UITableViewStyle) {
        super.init(style: style)
        // Custom initialization
    }

    override func viewDidLoad() {
        super.viewDidLoad()


    }

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

    // #pragma mark - Table view data source

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

    override func tableView(tableView: UITableView?, numberOfRowsInSection section: Int) -> Int {
        return 5
    }


    override func tableView(tableView: UITableView?, cellForRowAtIndexPath indexPath: NSIndexPath?) -> UITableViewCell? {
        var cell = tableView?.dequeueReusableCellWithIdentifier("Cell") as? UITableViewCell

        if !cell {
            cell = UITableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: "Cell")
        }
        cell!.textLabel.text = "test"
        return cell
    }

}

和appDelegate看起来像这样：

and the appDelegate looks like this:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

        let mainViewController: UITableViewController = MainViewController(style: UITableViewStyle.Plain)
        let navigationController: UINavigationController = UINavigationController()
        navigationController.pushViewController(mainViewController, animated: false)

        self.window!.rootViewController = navigationController
        self.window!.backgroundColor = UIColor.whiteColor()
        self.window!.makeKeyAndVisible()
        return true
    }

程序运行，但是一旦运行，我就会收到以下错误：

The program run, but as soon as it does, I get the following error:

fatal error: use of unimplemented initializer 'init(nibName:bundle:)' for class 'HelloWorld.MainViewController'

然后我更改了 MainViewController（样式：UITableViewStyle.Plain）到 MainViewController（nibName：n il，bundle：nil）但是我得到以下语法错误：调用中的额外参数'bundle'

I then changes the MainViewController(style: UITableViewStyle.Plain) to MainViewController(nibName: nil, bundle: nil) but then I get the following syntax error: Extra argument 'bundle' in call

非常感谢任何帮助

推荐答案

我正在使用UITableViewController的子类而没有任何问题，使用（nibName：bundle :)表单，但我在我的子类中重写了它。我尝试用标准的UITableViewController替换我的子类，它仍然工作正常。您是否可能覆盖子类中的init（...）方法？

I'm using a subclass of UITableViewController with no issues, using the (nibName:bundle:) form, but I've overridden that in my subclass. I tried replacing my subclass with a standard UITableViewController, and it still worked fine. Are you possibly overriding an init(...) method in your subclass?
