从 swift 文件中的结构获取信息

Question

所以我有一个类 swift 文件，它有一个像这样的 UserAccount 类

class UserAccount{

 var userName: String!
 var email: String!
 var instaGram: String!
 var timeCreated: String!
 var like: String!
 var role: String!
 var active: String!
 var id: String!


init(userName: String, email: String, instaGram: String, timeCreated: String, like: String, role: String, active: String, id: String){

    self.userName = userName
    self.email = email
    self.instaGram  = instaGram
    self.timeCreated = timeCreated
    self.like = like
    self.role = role
    self.active = active
    self.id = id

 }

}

我有登录视图控制器，我在其中获取类变量并执行我的 json 并像这样分配它们的值：

var userAcount = [UserAccount]() // Array Of Object
var user = UserAccount(userName: "", email: "", instaGram: "", timeCreated: "", like: "", role: "", active: "", id: "") //Init of Object

这是我获取我的 Json 并将其值添加到其相应的用户类变量的地方，我在我的登录视图控制器上执行此操作：

self.user.userName = userData.value(forKey: "userName") as! String
self.user.email = userData.value(forKey: "email") as! String
self.user.instaGram = userData.value(forKey: "instaGram") as! String
self.user.timeCreated = userData.value(forKey: "timeCreated") as! String
self.user.role = userData.value(forKey: "role") as! String
self.user.like = userData.value(forKey: "likes") as! String
self.user.id = userData.value(forKey: "id") as! String
self.user.active = userData.value(forKey: "active") as! String

这是我将信息附加到我的类数组的地方：

self.userAcount.append(self.user)

现在我的问题是我不知道如何在其他视图控制器上显示 UserAccount 类中的信息，例如用户配置文件视图控制器，这是我第一次使用用户和配置文件，任何帮助将不胜感激，谢谢你

向另一个UIViewController提供数据

1. 使用Storyboard 或segue

   override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
      if segue.identifier == "your_identifier", 
         let destinationVC = segue.destination as? YourViewController {
           destinationVC.userAcount = self.userAcount
       }
   }
   

2. 以编程方式

   func gotoNextVC() {
       let destinationVC = YourViewController(nibName: "YourViewController", bundle: nil)
       destinationVC.userAcount = self.userAcount
       self.navigationController?.pushViewController(destinationVC, animated: true)
   
       // OR
       self.present(destinationVC, animated: true, completion: nil)
   }

在另一个 ViewController 中创建您的 UserAccount 的实例。 当你唤醒新的视图控制器时，传递 UserAccount 的值，传递值你有两个选择 1。故事板/转场

func prepare(for segue: UIStoryboardSegue, sender: Any?){
      if segue.identifier == "identifier"{ 
        let destinationVC = segue.destination as? YourViewController
        destinationVC.userAcount = self.userAcount
      }
   }

2。按代码

let storyBoard = UIStoryboard(name: "Main", bundle: Bundle.main)
   let controller = storyBoard.instantiateViewController(withIdentifier:      identifier)
   controller.user = self.user

现在要在您的 NewViewController 中访问，您只需通过

访问

let userName = self.user.userName
