搜索栏加载plist的问题

Question

我正在将我的plist加载到TableView中，并且它一切正常，但现在我正在尝试在Page1中包含一个SearchBar。下面你看到的directory.plist和我Main.storyboard

要正确加载的plist我把下面的代码放在我的didFinishLaunchingWithOptions：

class AppDelegate: UIResponder, UIApplicationDelegate { 

    var window: UIWindow? 

    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:Any]] { 
      Shared.instance.employees = array.map{Employee(dictionary: $0)} 
     } 
     return true 
} 

我也有一个结构帮助我加载所有我的东西：

struct EmployeeDetails { 
    let functionary: String 
    let imageFace: String 
    let phone: String 

    init(dictionary: [String: Any]) { 
     self.functionary = (dictionary["Functionary"] as? String) ?? "" 
     self.imageFace = (dictionary["ImageFace"] as? String) ?? "" 
     self.phone = (dictionary["Phone"] as? String) ?? "" 
    } 
} 
struct Employee { 
    let position: String 
    let name: String 
    let details: [EmployeeDetails] // [String:Any] 

    init(dictionary: [String: Any]) { 
     self.position = (dictionary["Position"] as? String) ?? "" 
     self.name = (dictionary["Name"] as? String) ?? "" 

     let t = (dictionary["Details"] as? [Any]) ?? [] 
     self.details = t.map({EmployeeDetails(dictionary: $0 as! [String : Any])}) 
    } 
} 

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

直到这里，一切都运行良好！现在我成了有问题，当我试图插入一个搜索查看，看看我做了什么至今：

class Page1: UITableViewController, UISearchBarDelegate { 

    @IBOutlet weak var searchBar: UISearchBar! 

    let employeesSearching: [String] = [String]() //now using: var employeesSearching = [Employee]() 
    var isSearching : Bool = false 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     self.searchBar.delegate = self 
    } 

    override func numberOfSections(in tableView: UITableView) -> Int { 
     return 1 
    } 

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     if self.isSearching == true { 
      return self.employeesSearching.count 
     } else { 
      return Shared.instance.employees.count 
     } 
    } 

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
     let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell1 
     let employee = Shared.instance.employees[indexPath.row] 

     if self.isSearching == true { 
      cell.nameLabel.text = self.employeesSearching[indexPath.row].name 
      cell.positionLabel.text = self.employeesSearching[indexPath.row].position 
     } else { 
      cell.nameLabel.text = employee.name 
      cell.positionLabel.text = employee.position 
     } 
     return cell 
    } 

    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) { 
     if self.searchBar.text!.isEmpty { 
      self.isSearching = false 
      self.tableView.reloadData() 
     } else { 
      self.isSearching = true 
      self.employeesSearching.removeAll(keepingCapacity: false) 
      for i in 0..<self.Shared.instance.itens.count { 
       let listItem : String = self.Shared.instance.itens[i] 
       if listItem.lowercased().range(of: self.searchBar.text!.lowercased()) != nil { 
        self.employeesSearching.append(listItem) 
       } 
      } 
      self.tableView.reloadData() 
     } 
    } 

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) { 
     if let destination = segue.destination as? Page2, 
      let indexPath = tableView.indexPathForSelectedRow { 
      destination.newPage = Shared.instance.employees[indexPath.row] 
     } 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
    } 
} 

这些都是完全相同的错误：

Answer 1

的错误是因为employeesSearching是String恒定阵列。

您可能需要一个Employee的变量数组。

变化：

let employeesSearching: [String] = [String]() 

到：

var employeesSearching = [Employee]()
