标题: ios - 调用 plist 的子项

这是我的属性(property) list :directory.plist

我想知道如何将子项调用到 ViewController 中。这是我的实际 ViewController:

import UIKit

class Page1: UIViewController {

    @IBOutlet weak var nameLabel: UILabel!
    @IBOutlet weak var positionLabel: UILabel!
    @IBOutlet weak var phoneLabel: UILabel!
    @IBOutlet weak var emailLabel: UILabel!

    override func viewDidLoad() {
    super.viewDidLoad()

        Shared.instance.employees.forEach({

            nameLabel.text = (("name:", $0.name) as? String)

            print("name:", $0.name)
            print("position:", $0.position)
            print("phone:", $0.phone)
            print("email:", $0.email)
            print()
        })
    }
}

这是我正在使用的结构:

import UIKit

struct Employee {
    let position: String
    let name: String
    let email: String
    let phone: String
    init(dictionary: [String: String]) {
        self.position = dictionary["osition"] ?? ""
        self.name = dictionary["Name"] ?? ""
        self.email = dictionary["Email"] ?? ""
        self.phone = dictionary["hone"] ?? ""
    }
}

struct Shared {
    static var instance = Shared()
    var employees: [Employee] = []
}

在 AppDelegate 里面我放了这个:

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        if let url = Bundle.main.url(forResource: "directory", withExtension: "plist"), let array = NSArray(contentsOf: url) as? [[String: String]] {
            Shared.instance.employees = array.map{Employee(dictionary: $0)}
    }
    return true

我必须调用我的 directory.plist 上的子项吗？我的意思是关键细节里面的项目。然后我想展示 Func1、Func2 和 Func3。

obs.这个func是functionary的缩写)

谢谢!

经过一些更改，现在我的子项为零:debugger

Best Answer-推荐答案

您在应用程序委托(delegate)中的代码很好。您只需要使用另一个属性更新您的 Employee 结构来存储 Details。但这也意味着您的员工字典不仅仅是字符串值的字典。所以你需要更新代码来处理正确的值类型:

struct Employee {
    let position: String
    let name: String
    let email: String
    let phone: String
    let details: [String:String]

    init(dictionary: [String: Any]) {
        self.position = (dictionary["osition"] as? String) ?? ""
        self.name = (dictionary["Name"] as? String) ?? ""
        self.email = (dictionary["Email"] as? String) ?? ""
        self.phone = (dictionary["hone"] as? String) ?? ""
        self.details = (dictionary["Details"] as? [String:String]) ?? [:]
    }
}
