Programmatically navigate to another view controller/scene

提问by Mohammad Nurdin

I got an error message during navigating from first view controller to second view controller. My coding is like this one

我在从第一个视图控制器导航到第二个视图控制器时收到一条错误消息。我的编码是这样的

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

The problem is I always got this kind of error message

问题是我总是收到这种错误信息

Try this one. Here "LoginViewController" is the storyboardID specified in storyboard.

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

See below

见下文

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

XCODE 8.2 AND SWIFT 3.0

Xcode 8.2 和 Swift 3.0

Present an exist UIViewController

存在 UIViewController

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

Push an exist UIViewController

推送一个存在 UIViewController

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

Remember that you can put the UIViewControllerIdentifier following the next steps:

请记住，您可以按照UIViewController以下步骤放置标识符：

• Select Main.storyboard
• Select your UIViewController
• Search the Utilities in the right
• Select the identity inspector
• Search in section identity "Storyboard ID"
• Put the Identifier for your UIViewController

• 选择 Main.storyboard
• 选择您的 UIViewController
• 搜索右侧的实用程序
• 选择身份检查员
• 在部分身份“故事板 ID”中搜索
• 把标识符放在你的 UIViewController

If you want to navigate to Controller created Programmatically, then do this:

如果要导航到以编程方式创建的控制器，请执行以下操作：

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

If you want to navigate to Controller on StoryBoard with Identifier "newViewController", then do this:

如果要使用标识符“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)

See mine.

看我的。

func actioncall () {
    let loginPageView = self.storyboard?.instantiateViewControllerWithIdentifier("LoginPageID") as! ViewController
    self.navigationController?.pushViewController(loginPageView, animated: true)
}

If you use presenting style, you might lose the page's navigation bar with preset pushnavigation.

如果您使用呈现样式，您可能会丢失带有预设推送导航的页面导航栏。

You can move from one scene to another programmatically using below code :

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) 

Here storyBoardID is value that you set to scene using Interface Builder. This is shown below :

这里的 storyBoardID 是您使用 Interface Builder 为场景设置的值。这如下所示：

Swift3:

斯威夫特3：

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

Try this out. You just confused nib with storyboard representation.

试试这个。您只是将笔尖与故事板表示混淆了。

Programmatically there are different ways based on different situations

编程上根据不同情况有不同的方法

1. load storyenter code hereboard nib file

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

2. Load from xib

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

3. Navigate through Segue

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

1. 在此处加载 storyenter 代码 nib 文件

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

2. 从xib加载

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

3. 浏览 Segue

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

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

You can do navigation between view controllers using code with the help of storyboard and storyboardId of the view controller. This code is for Swift 3:

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)
