將數據從plist加載到兩個TableViews

我有一些麻煩從我的屬性列表中加載一些數據。看看... 這是我directory.plist：將數據從plist加載到兩個TableViews

我想告訴所有這一切，就在這裏Main.storyboard：

但鍵PositionËName將出現在第一TableViewController和密鑰Functionary,ImageFace和Phone必須出現在第二個TableViewController。

要做到這一點，我做了這個：

加入AppDelegate中如下：

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

創建一個Struct這樣的：

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] = [] 
}

我首先TableViewController，是這樣的：

class Page1: UITableViewController { 

override func viewDidLoad() { 
    super.viewDidLoad() 

    let anEmployee = Shared.instance.employees[1] 

    print("Name:", anEmployee.name) 
    print("Position:", anEmployee.position) 

    anEmployee.details.forEach({ 

     print("Functionary:", $0.functionary) 
     print("ImageFace:", $0.imageFace) 
     print("Phone:", $0.phone) 
    }) 
} 

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

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    return Shared.instance.employees.count 
} 

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell1 

     cell.nameLabel.text = Shared.instance.employees[indexPath.row].name 
     cell.positionLabel.text = Shared.instance.employees[indexPath.row].position 

     return cell 
    } 

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].details[indexPath.row] 
     tableView .deselectRow(at: indexPath, animated: true) 
     } 
    } 
}

我二TableViewController，在這裏：

var newPage: EmployeeDetails! //recently added 

class Page2: UITableViewController { 

var newPage: EmployeeDetails! 

override func viewDidLoad() { 
    super.viewDidLoad() 

    if let theEmployee = newPage { 
     self.title = theEmployee.name 
    } 
} 

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

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    if let theEmployee = newPage { 
     return theEmployee.details.count 
    } 
return 0 
} 

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell2 

    if let theEmployee = newPage { 

     cell.faceImage.image = theEmployee.details[indexPath.row].imageFace as? UIImage // did not work 
     cell.functionary.text = theEmployee.details[indexPath.row].functionary 
     cell.phoneLabel.text = theEmployee.details[indexPath.row].phone 
    } 
    return cell 
    } 
}

當我在第一TableViewController的任何物品觸碰，我看到第二TableViewController完全空了！和調試區域顯示它：

2017-03-28 17:16:28.456 plist sample[7138:425253] Unknown class Page2 in Interface Builder file.

根據您的plist結構：

Shared.instance.employees[indexPath.row].details

details是字典的數組。你正在把它當作一本詞典。

編輯：最初的問題是正確的...多種方式來解決它（如你所見/完成）。另一種選擇，這可能會或可能不會有所幫助：

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] = [] 
}

然後你可以做你的原文：

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)} 

    }

，然後通過訪問數據：

let anEmployee = Shared.instance.employees[0] 

    print("Name:", anEmployee.name) 
    print("Position:", anEmployee.position) 

    print("Detail 0 Functionary:", anEmployee.details[0].functionary) 
    print("Detail 0 ImageFace:", anEmployee.details[0].imageFace) 
    print("Detail 0 Phone:", anEmployee.details[0].phone) 

    // or 

    anEmployee.details.forEach({ 

     print("Functionary:", $0.functionary) 
     print("ImageFace:", $0.imageFace) 
     print("Phone:", $0.phone) 

    })

只是舉例。

我剛更新了這個問題。 –

嗯......好的......你明白我的回答嗎？當它是一個字典的「數組」時，你會將'details'當作'Dictionary'處理。在我的回答中看到編輯 – DonMag

現在我有下面的錯誤信息：對Functionary和ImageFace的印刷品上'成員下標'的歧義引用。 –
