Swift를 사용하여 한 View 컨트롤러에서 다른 View 컨트롤러로 이동하는 방법

Swift를 사용하여 한 View 컨트롤러에서 다른 View 컨트롤러로 이동하는 방법

한 뷰 컨트롤러에서 다른 뷰 컨트롤러로 이동하고 싶습니다.다음 Objective-C 코드를 Swift로 변환하려면 어떻게 해야 합니까?

UIViewController *viewController = [[self storyboard] instantiateViewControllerWithIdentifier:@"Identifier"];
UINavigationController *navi = [[UINavigationController alloc] initWithRootViewController:viewController];
[self.navigationController pushViewController:navi animated:YES];

두 번째 보기 컨트롤러에 대한 swift 파일(SecondViewController.swift)을 만들고 적절한 함수에 다음과 같이 입력합니다.

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

스위프트 2+

let mapViewControllerObj = self.storyboard?.instantiateViewControllerWithIdentifier("MapViewControllerIdentifier") as? MapViewController
self.navigationController?.pushViewController(mapViewControllerObj!, animated: true)

---

스위프트 4

let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "IKDetailVC") as? IKDetailVC
self.navigationController?.pushViewController(vc!, animated: true)

내 경험으로는navigationController0이었기 때문에 코드를 다음과 같이 변경했습니다.

let next = self.storyboard?.instantiateViewControllerWithIdentifier("DashboardController") as! DashboardController
self.presentViewController(next, animated: true, completion: nil)

ViewController를 설정하는 것을 잊지 마십시오.StoryBoard Id에StoryBoard->identity inspector

사용자가 로그인한 후에 표시하려고 했기 때문에 뒤로 단추를 표시하지 않으려면 다음과 같이 Nav 컨트롤러의 루트를 설정합니다.

let vc = self.storyboard?.instantiateViewControllerWithIdentifier("YourViewController") as! YourViewController
        let navigationController = UINavigationController(rootViewController: vc)
        self.presentViewController(navigationController, animated: true, completion: nil)

SWIFT 3.01

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

인스위프트 4.0

var viewController: UIViewController? = storyboard().instantiateViewController(withIdentifier: "Identifier")
var navi = UINavigationController(rootViewController: viewController!)
navigationController?.pushViewController(navi, animated: true)

Swift 4.1 및 Xcode 10에서

여기서 AddFileViewController는 두 번째 뷰 컨트롤러입니다.

스토리보드 ID는 AFVC입니다.

let next = self.storyboard?.instantiateViewController(withIdentifier: "AFVC") as! AddFileViewController
self.present(next, animated: true, completion: nil)

//OR

//If your VC is DashboardViewController
let dashboard = self.storyboard?.instantiateViewController(withIdentifier: "DBVC") as! DashboardViewController
self.navigationController?.pushViewController(dashboard, animated: true)

필요한 경우 나사산을 사용합니다.

예:

DispatchQueue.main.async { 
    let next = self.storyboard?.instantiateViewController(withIdentifier: "AFVC") as! AddFileViewController
    self.present(next, animated: true, completion: nil) 
}

시간이 좀 지난 후에 이사하고 싶다면요.

EX:

//To call or execute function after some time(After 5 sec)
DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {
    let next = self.storyboard?.instantiateViewController(withIdentifier: "AFVC") as! AddFileViewController
    self.present(next, animated: true, completion: nil) 
} 

let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let home = storyBoard.instantiateViewController(withIdentifier: "HOMEVC") as! HOMEVC
navigationController?.pushViewController(home, animated: true);

스위프트 3

let secondviewController:UIViewController =  self.storyboard?.instantiateViewController(withIdentifier: "StoryboardIdOfsecondviewController") as? SecondViewController

self.navigationController?.pushViewController(secondviewController, animated: true)

인스위프트 3

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

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

Segue를 사용하여 한 View 컨트롤러에서 다른 View 컨트롤러로 이동합니다.

performSegue(withIdentifier: "idView", sender: self)

이것은 Xcode 10.2에서 작동합니다.

Swift 4 및 5의 경우 사용자는 이 방법을 사용할 수 있습니다.

스위프트 5

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

스위프트 4

let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "YourViewController") as? YourViewController 
self.navigationController?.pushViewController(vc!, animated: true)

Swift 5.0의 모범 사례

프로토콜 만들기

protocol Storyboarded { }

이제 프로토콜의 확장을 만듭니다.

extension Storyboarded where Self: UIViewController {
    
    static func instantiateFromMain() -> Self {
        let storyboardIdentifier = String(describing: self)
        // `Main` can be your stroyboard name.
        let storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)
        
        guard let vc = storyboard.instantiateViewController(withIdentifier: storyboardIdentifier) as? Self else {
            fatalError("No storyboard with this identifier ")
        }
        return vc
    }
}
// Make a ViewController extension to use on all of your ViewControllers
extension UIViewController: Storyboarded {}

사용방법

  let vc = MyViewController.instantiateFromMain()
  //here you can pass any data to the next view controller. for example we have a variable with name `myString` in our next view contoller and we want to pass the data my `self viewController`
  vc.myString = "This string passed by MyViewController"
  self.navigationController?.pushViewController(vc, animated: true)

참고:- 스토리보드에 있는 ID와 동일한 ID를 지정해야 합니다.UIViewController계급이 있었습니다.아래 예를 확인하십시오.

내비게이션 컨트롤러를 눌러 화면을 전환할 수 있습니다. 먼저 UIViewController를 사용하여 내비게이션 컨트롤러를 설정해야 합니다.

let vc = self.storyboard?.instantiateViewController(withIdentifier: "YourStoryboardID") as! swiftClassName

self.navigationController?.pushViewController(vc, animated: true)

AppDelegate에서 다음과 같이 쓸 수 있습니다.

var window: UIWindow?

fileprivate let navigationCtrl = UINavigationController()

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    self.createWindow()

    self.showLoginVC()

    return true
}

func createWindow() {
    let screenSize = UIScreen.main.bounds
    self.window = UIWindow(frame: screenSize)
    self.window?.backgroundColor = UIColor.white
    self.window?.makeKeyAndVisible()
    self.window?.rootViewController = navigationCtrl
}

func showLoginVC() {
    let storyboardBundle = Bundle.main
    // let storyboardBundle = Bundle(for: ClassName.self) // if you are not using main application, means may be you are crating a framework or library you can use this statement instead
    let storyboard = UIStoryboard(name: "LoginVC", bundle: storyboardBundle)
    let loginVC = storyboard.instantiateViewController(withIdentifier: "LoginVC") as! LoginVC
    navigationCtrl.pushViewController(loginVC, animated: false)
}

Swift 5에 대한 업데이트:

    let next = self.storyboard?.instantiateViewController(withIdentifier: "SecondViewController") as! SecondViewController

    self.present(next, animated: true, completion: nil)

두 View 컨트롤러의 스토리보드 ID를 업데이트하는 것을 잊지 마십시오!
