Ios Swift:tabcontroller中的表格只有在'；第一张账单是什么？

我附上了示例代码，说明了我遇到的问题。出于某种原因，tableview需要成为tableviewcontroller识别导航栏的第一个选项卡。这个问题是这个问题的延伸

这里有一个指向实际示例项目的链接

AppDelegate：

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    window = UIWindow(frame: UIScreen.mainScreen().bounds)
    let containerViewController:ContainerViewController = ContainerViewController()
    window!.rootViewController = containerViewController
    window!.makeKeyAndVisible()
    return true
}

ContainerViewController.swift：

class ContainerViewController: UIViewController, LoginDelegate {

var mainNavigationController: UINavigationController!
var myTabBarController: UITabBarController!
var loginViewController: LoginViewController!


override func viewDidLoad() {
    super.viewDidLoad()
    var mainStoryboard: UIStoryboard =  UIStoryboard(name: "Main", bundle: NSBundle.mainBundle())
    myTabBarController = mainStoryboard.instantiateViewControllerWithIdentifier("myTabBarController") as? UITabBarController
    loginViewController = mainStoryboard.instantiateViewControllerWithIdentifier("loginViewController") as? LoginViewController
    loginViewController.delegate = self

    mainNavigationController = UINavigationController(rootViewController: loginViewController)
    view.addSubview(mainNavigationController.view)
    addChildViewController(mainNavigationController)
    mainNavigationController.didMoveToParentViewController(self)
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

func loginPressed() {
    self.mainNavigationController.pushViewController(self.myTabBarController, animated: false)
}

@objc
protocol LoginDelegate{
func loginPressed()
}

class LoginViewController: UIViewController {

@IBOutlet var loginBtn: UIButton!
 var delegate: LoginDelegate?

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

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}
@IBAction func loginPressed(sender: AnyObject) {
    delegate?.loginPressed()
}
}

class FirstTabViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController?.topViewController.navigationItem.setHidesBackButton(true, animated: true)
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}
}

class SecondTabViewController: UITableViewController {

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

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

}

    loginViewController.delegate = self

    mainNavigationController = UINavigationController(rootViewController: loginViewController)
    view.addSubview(mainNavigationController.view)
    addChildViewController(mainNavigationController)
    mainNavigationController.didMoveToParentViewController(self)
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

func loginPressed() {
    self.mainNavigationController.pushViewController(self.myTabBarController, animated: false)

我通读了您的代码并运行了您的项目，我相信问题在于您正在将UITabBarController嵌入UINavigationController中。您要做的是将每个UIViewController（或UITableViewController）嵌入到自己的UINavigationController中，然后将这些导航控制器设置为UITabBarController的视图控制器（即，您可以在情节提要上进行设置）

这就是为什么您的第二个选项卡（隐藏在导航栏下的第一行）上的tableviewcontroller的内容插入也存在问题的原因。嵌入UITabBarController的UINavigationController没有通过UITabBarController将正确的插入传递给其视图控制器

我对您的项目做了一些更改：

---

Main.storyboard

我将每个UITabBarController的视图控制器嵌入到它自己的UINavigationController中

---

ContainerViewController

我将loginViewController和myTabBarController的视图添加为容器VC视图的子视图，然后将每个控制器添加为容器VC的子控制器。如果您想要导航栏，仍然可以将loginViewController嵌入UINavigationController中，但为了简单起见，我删除了它

---

FirstTabViewController

由于此视图控制器现在嵌入到情节提要中自己的UINavigationController中，因此它可以像self.navigationItem一样访问其navigationItem

---

非常感谢马克！！我一直在等待答复，因为在您最初的答复之后，我与导航控制器有问题。我认为你的扩展答案将帮助我走出困境！！
