Swift 3故事板导航

Question

我有一个名为LoginViewController.swift的文件中内置的登录页面

在用户登录后，我希望将它们发送到构建在TabBarController上的新情节提要中。

​

第2项(中间部分)链接到一个名为landingViewController.swift的文件，该文件包含：

import UIKit

class landingViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


}

在我的LoginViewController中，我想导航到函数的API部分中的新故事板，我已经创建了一个注释区域来向您展示。

//MARK: -API Request
func logintoUnicityLife(username:String , password:String){
    let params = ["username": username,
                  "password": password]

    print("login API called - \(params)")

    Alamofire.request(URL(string: "\(AppData.sharedData.APIUrl)/login")!,
                      method: .get,
                      parameters: params,
                      headers: AppData.sharedData.headerParam).validate().responseJSON(completionHandler: {(response) -> Void in
                        print("login API done - \(response.response?.statusCode)")

                        guard response.result.isSuccess else {
                            print("API fail: \(response.error.debugDescription)")
                            return
                        }
                        guard let value = response.result.value as? Dictionary<String, Any>,
                            let result = value["result"] as? Dictionary<String, String> else {
                                print(response)
                                return
                        }

                        self.userDetails = result
                        print(self.userDetails)

                        // =========== NAVIGATE TO THE NEW STORYBOARD HERE =============

                        // =========== CODE GOES ABOVE HERE ==================

                      })
}

func logintoUnicityLife(username:String , password:String){
        let params = ["username": username,
                      "password": password]

        print("login API called - \(params)")

        Alamofire.request(URL(string: "\(AppData.sharedData.APIUrl)/login")!,
                          method: .get,
                          parameters: params,
                          headers: AppData.sharedData.headerParam).validate().responseJSON(completionHandler: {(response) -> Void in
                            print("login API done - \(response.response?.statusCode)")

                            guard response.result.isSuccess else {
                                print("API fail: \(response.error.debugDescription)")
                                return
                            }
                            guard let value = response.result.value as? Dictionary<String, Any>,
                                let result = value["result"] as? Dictionary<String, String> else {
                                    print(response)
                                    return
                            }

                            self.userDetails = result
                            print(self.userDetails)

                            // Tabbarcontrolloer set as initial ViewController
                            let tabVC = UIStoryboard(name:"<Your Storyboard file name>", bundle:nil).instantiateInitialViewController()
                            (UIApplication.shared.delegate as? AppDelegate)?.window?.rootViewController = tabVC

                            // =========== NAVIGATE TO THE NEW STORYBOARD HERE =============

                            // =========== CODE GOES ABOVE HERE ==================

                          })
    }

1. 将第二个情节提要中的选项卡视图控制器设置为初始视图控制器
2. 成功登录后，执行以下代码 设storyBoard =UIStoryboard(名称：“第二个”，bundle:nil) //第二个故事板名为第二个let tabVC = storyBoard.instantiateInitialViewController() (UIApplication.shared.delegate as？( AppDelegate)?.window?.rootViewController = tabVC

或

1. 将情节提要id设置为第二个情节提要中的tabview控制器。
2. 成功登录后，执行以下代码 设storyBoard =UIStoryboard(名称：“第二个”，bundle:nil)//第二个故事板名称作为第二个let tabVC =UIStoryboard " tabVc ") // tabVc选项卡视图控制器的故事板id被指定为tabVc (UIApplication.shared.delegate as？( AppDelegate)?.window?.rootViewController = tabVC

Answer 3

一种方法是在Login故事板中创建一个故事板引用，在LoginViewController和故事板引用之间创建一个segue，给它一个"fromLoadingToMain“的标识符，如下所示：

​

​

然后在您的代码中，只需做：

// =========== NAVIGATE TO THE NEW STORYBOARD HERE =============
self.performSegue(withIdentifier: "fromLoadingToMain", sender: nil)
// =========== CODE GOES ABOVE HERE ==================
