爲什麼不在嵌入時顯示UITableView UINavigationController

Question

我是iOS開發新手。我正在學習Swift。我目前有一個問題，我添加一個導航視圖控制器後，我的tableView不再顯示任何東西。我不明白爲什麼。請幫助我的專家！

class AppDelegate: UIResponder, UIApplicationDelegate { 

var window: UIWindow? 


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
    // Override point for customization after application launch. 

    let mainVC = ViewController() 
    let navigationVC = UINavigationController(rootViewController: mainVC) 
    window?.rootViewController = navigationVC; 
    window?.makeKeyAndVisible() 
    return true 
} 

代碼中的ViewController：

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { 
@IBOutlet var myTable: UITableView! 
var items: [String] = ["Date Picker","List of Data","Slider","Show Image", "Web Display"]; 

override func viewDidLoad() { 
    super.viewDidLoad() 

    NSLog("Hello World at console"); 
    var nib = UINib(nibName: "ListCell", bundle: nil) 
    myTable?.registerNib(nib, forCellReuseIdentifier: "ListCell") 
    // Do any additional setup after loading the view, typically from a nib. 
}

如果您使用的故事板使用它的實例化方法，並在故事板

YourController *vc = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"ControllerStoryboardId"]; 

如果XIB文件

設置你的控制器的storyboardID

YourController *vc = [[YourController alloc] initWithNibName:@"YourController" bundle:[NSBundle mainBundle]];
