Question

从第一个视图控制器导航到第二个视图控制器时出现错误消息。我的编码就像这个

let vc = LoginViewController(nibName: "LoginViewController", bundle: nil)
self.navigationController?.pushViewController(vc, animated: true)

问题是我总是收到这种错误信息

Answer 1

我已经找到了答案

Swift 4

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "nextView") as! NextViewController
self.present(nextViewController, animated:true, completion:nil)

Swift 3

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)

let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("nextView") as NextViewController
self.presentViewController(nextViewController, animated:true, completion:nil)

Answer 2

试试这个。这里“LoginViewController”是storyboard中指定的storyboardID。

见下文

let secondViewController = self.storyboard?.instantiateViewControllerWithIdentifier("LoginViewController") as LoginViewController
self.navigationController?.pushViewController(secondViewController, animated: true)

Answer 3

XCODE 8.2 AND SWIFT 3.0

呈现存在的UIViewController

let loginVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "LoginViewController") as! LoginViewController
self.present(loginVC, animated: true, completion: nil)

推送存在的UIViewController

let loginVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "LoginViewController") as! LoginViewController
self.navigationController?.pushViewController(loginVC, animated: true)

请记住，您可以按照以下步骤放置UIViewController标识符：

选择Main.storyboard
选择UIViewController
搜索右侧的实用程序
选择身份检查员
搜索部分标识“Storyboard ID”
为您的UIViewController

Answer 4

见我的。

input_data = LOAD '$INPUT' USING PigStorage('|') AS (user_id:chararray ...)
static_data = LOAD ... AS (req_user_id:chararray

required_data = JOIN input_data BY useriD, static_data BY req_user_id  USING 'replicated';

required_data_fmt = -- project required fields.

如果您使用呈现样式，则可能会丢失具有预设pushnavigation的页面导航栏。

Answer 5

如果要导航到以编程方式创建的Controller，请执行以下操作：

let newViewController = NewViewController()
self.navigationController?.pushViewController(newViewController, animated: true)

如果您想使用标识符“newViewController”导航到StoryBoard上的Controller，请执行以下操作：

let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "newViewController") as! NewViewController
        self.present(newViewController, animated: true, completion: nil)

Answer 6

您可以使用以下代码以编程方式从一个场景移动到另一个场景：

  let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)

  let objSomeViewController = storyBoard.instantiateViewControllerWithIdentifier(“storyboardID”) as! SomeViewController

  // If you want to push to new ViewController then use this
  self.navigationController?.pushViewController(objSomeViewController, animated: true)

  // ---- OR ----

  // If you want to present the new ViewController then use this
  self.presentViewController(objSomeViewController, animated:true, completion:nil)

这里storyBoardID是您使用Interface Builder设置为场景的值。如下所示：

Answer 7

<强> Swift3：

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController("LoginViewController) as UIViewController
self.navigationController?.pushViewController(vc, animated: true)

试一试。你只是把笔尖与故事板表示混淆了。

Answer 8

let VC1 = self.storyboard!.instantiateViewController(withIdentifier: "MyCustomViewController") as! ViewController
let navController = UINavigationController(rootViewController: VC1)
self.present(navController, animated:true, completion: nil)

Answer 9

根据情况，程序上有不同的方式

在Storyboard笔尖文件中加载Storyenter代码

let yourVc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "YourViewController") as! YourViewController self.present(yourVc, animated: true, completion: nil)
从xib加载

let yourVc = YourViewController.init(nibName: "YourViewController", bundle: nil) self.present(yourVc, animated: true, completion: nil)
通过Segue导航

self.performSegue(withIdentifier: "your UIView", sender: self)

Answer 10

我给你我的代码进行转换。在此示例中，操作连接到UIButton。所以不要忘记设置它。不要忘记在transition方法中设置ViewController的名称。

不要忘记设置故事板。您需要为每个viewController提供一个视图。将每个ViewController连接到storyBoard中的每个视图。您可以在下面的屏幕截图中看到

enter image description here

class PresentationViewController: UIViewController {
    override func viewDidLoad() {
         super.viewDidLoad()

         var playButton   = UIButton.buttonWithType(UIButtonType.System) as UIButton

         let image = UIImage(named: "YourPlayButton") as UIImage?

         playButton.frame = CGRectMake(0, 0, 100, 100)
         playButton.center = CGPointMake(self.view.frame.width/2, self.view.frame.height/2)
         playButton.addTarget(self, action: "transition:", forControlEvents:  UIControlEvents.TouchUpInside)
         playButton.setBackgroundImage(image, forState: UIControlState.Normal)

         self.view.addSubview(playButton)
    }


func transition(sender:UIButton!)
{
    println("transition")
    let secondViewController = self.storyboard?.instantiateViewControllerWithIdentifier("YourSecondViewController") as UIViewController

    let window = UIApplication.sharedApplication().windows[0] as UIWindow
    UIView.transitionFromView(
        window.rootViewController!.view,
        toView: secondViewController.view,
        duration: 0.65,
        options: .TransitionCrossDissolve,
        completion: {
            finished in window.rootViewController = secondViewController
    })
}
}

Answer 11

您可以在视图控制器的storyboard和storyboardId的帮助下使用代码在视图控制器之间进行导航。此代码适用于Swift 3：

let signUpVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SignUp")
self.navigationController?.pushViewController(signUpVC, animated: true)

Answer 12

如果您在没有拖放的情况下构建UI（不使用故事板）并希望将默认页面或ViewController.swift导航到另一个页面？跟着这些步骤 1）添加一个类（.swift） 2）导入UIKit 3）声明类名称，如

class DemoNavigationClass :UIViewController{
     override func viewDidLoad(){
         let lbl_Hello = UILabel(frame: CGRect(x:self.view.frame.width/3, y:self.view.frame.height/2, 200, 30));
lbl_Hello.text = "You are on Next Page"
lbl_Hello.textColor = UIColor.white
self.view.addSubview(lbl_Hello)
    }
}

创建第二页后返回第一页（ViewController.swift）这里在viewDidLoad方法中创建一个按钮

let button = UIButton()
button.frame = (frame: CGRect(x: self.view.frame.width/3, y: self.view.frame.height/1.5,   width: 200, height: 50))
 button.backgroundColor = UIColor.red
 button.setTitle("Go to Next ", for: .normal)
 button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
 self.view.addSubview(button)

现在在同一个类

中的viewDidLoad（）之外定义buttonAction方法

func buttonAction(sender: UIButton!) 
{
    let obj : DemoNavigationClass = DemoNavigationClass();
    self.navigationController?.pushViewController(obj, animated: true)
}

保留一件我忘记的事情在main.storyboard中有一个带箭头的场景，选择该箭头并按删除按钮

现在拖放一个navigationcontroller并删除navaigation控制器附带的tableview。选择键盘上的navigationcontroller按下控件并将其拖到故事板上的另一个场景，即ViewController。这意味着您的viewcontroller成为root viewcontroller 希望这能帮助你谢谢在main.storyboard中，拖放navigationcontroller，

Answer 13

 let vc = DetailUserViewController()
 vc.userdetails = userViewModels[indexPath.row]
 self.navigationController?.pushViewController(vc, animated: true)

Answer 14

我认为您正在寻找这样的东西：

let signUpViewController = SignUpViewController()
present(signUpViewController, animated: true, completion: nil)

如果要全屏显示新页面：

present(signUpViewController, animated: true, completion: nil)

希望这会有所帮助:)

Answer 15

Swift 4.0.3

 @IBAction func registerNewUserButtonTapped(_ sender: Any) {

        print("---------------------------registerNewUserButtonTapped --------------------------- ");

        let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)

        let nextViewController = storyBoard.instantiateViewController(withIdentifier: "RegisterNewUserViewController") as! RegisterNewUserViewController
        self.present(nextViewController, animated:true, completion:nil)

    }

更改我们的控制器名称RegisterNewUserViewController

Answer 16

XCODE 9.2和SWIFT 3.0

没有Segue Connection

ViewController到NextViewcontroller

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "NextViewController") as! NextViewController
self.navigationController?.pushViewController(nextViewController, animated:true)

或

let VC:NextViewController = storyboard?.instantiateViewController(withIdentifier: "NextViewController") as! NextViewController
self.navigationController?.pushViewController(VC, animated: true)

Answer 17

除了上面的好答案，在您的应用程序的屏幕顶部设置导航视图控制器，您可以将其添加到块中的 AppDelegate.swift 文件，如下所示

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    window = UIWindow()
    window?.makeKeyAndVisible()
    window?.rootViewController = UINavigationController(rootViewController: LoginViewController())

    return true

}

Answer 18

let signUpVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SignUp")
// self.present(signUpVC, animated: false, completion: nil)
self.navigationController?.pushViewController(signUpVC, animated: true)

Answer 19

我不确定尝试以下步骤，我认为可能会出现错误，原因如下。

您在XCode之外重命名一些文件。要解决此问题，请从项目中删除文件并重新导入项目中的文件。
检查并添加缺少的Nib文件构建阶段 - ＆gt;复制捆绑资源。最后检查笔尖名称拼写，它是否正确，区分大小写。
检查文件检查器中的.xib / storyboard文件的属性，选择框中的属性“目标成员”，然后选择xib / storyboard文件与你的目标有关。
，例如错误的NIB类型。右键单击该文件，然后单击“获取信息”以验证该类型是否符合预期。

以编程方式导航到另一个视图控制器/场景
