NSUserDefaults Obiekt niestandardowy - Lista właściwości jest nieprawidłowa dla formatu: 200 (listy właściwości nie mogą zawierać obiektów typu CFType)

Question

Muszę nieprawidłowo używać niestandardowych obiektów dla NSUserDefaults. Błąd "Lista właściwości jest nieprawidłowa dla formatu: 200 (listy właściwości nie mogą zawierać obiektów typu" CFType ")". Poniżej znajduje się mój kod, klasa celu jest szczególnie interesująca, ponieważ właśnie tu zaadaptowałem protokół NSCoding.

Ten kod jest globalny.

func saveGoals (goals : [Goal]) { 
    var updatedGoals = NSKeyedArchiver.archivedDataWithRootObject(goals) 
    NSUserDefaults.standardUserDefaults().setObject(updatedGoals, forKey: "Goals") 
    NSUserDefaults.standardUserDefaults().synchronize() 
} 

func loadCustomObjectWithKey() -> [Goal] { 
    if let encodedObject : NSData = NSUserDefaults.standardUserDefaults().objectForKey("Goals") as? NSData { 
     var encodedObject : NSData? = NSUserDefaults.standardUserDefaults().objectForKey("Goals") as? NSData 
     var goal : [Goal] = NSKeyedUnarchiver.unarchiveObjectWithData(encodedObject!) as [Goal] 
     return goal 
    } else { 
     return [Goal]() 
    } 
} 

Ten kod znajduje się w GoalsViewController.

class GoalsViewController: MainPageContentViewController, UITableViewDelegate, UITableViewDataSource { 
    @IBOutlet var tableView: GoalsTableView! 

    var cell = GoalTableViewCell() 

    var goalsArray : Array<Goal> = [] // 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     self.tableView.delegate = self 
     self.tableView.dataSource = self 

     if var storedGoals: [Goal] = loadCustomObjectWithKey() as [Goal]? { 
      goalsArray = storedGoals 
     } 
     //retrieve data. 

     var goal = Goal(title: "Walk the Dog") 
     goalsArray.append(goal) 
     saveGoals(goalsArray) 

     self.tableView?.reloadData() 

     tableView.estimatedRowHeight = 44.0 
     tableView.rowHeight = UITableViewAutomaticDimension 

     var notification = NSNotificationCenter.defaultCenter() 

     notification.addObserver(self, selector: "finishCreatingGoal:", name: "FinishCreatingGoal", object: nil) 
    } 

func finishCreatingGoal(notification : NSNotification) { 
     if (notification.name == "FinishCreatingGoal") { 
      var userInfo = notification.userInfo! 
      var text = userInfo["text"]! as String 
      var index = userInfo["index"]! as Int 

      var cell = self.tableView.cellForRowAtIndexPath(NSIndexPath(forRow: index, inSection: 0)) as GoalTableViewCell 
      goalsArray[index].title = cell.goalTextField.text 
      saveGoalList(goalsArray) 

      self.tableView.reloadData() 
      self.tableView.scrollToRowAtIndexPath(NSIndexPath(forRow: index, inSection: 0), atScrollPosition: UITableViewScrollPosition.Middle, animated: true) 
     } 
    } 

Ten kod należy do klasy Goal.

import UIKit 

class Goal : NSObject, NSCoding { 

    var title : String? = "" 
    var checkmarked : Bool? = false 
    var isLastCell : Bool? = false 
    var enabled : Bool? = true 

    var priority = Priority.defaultPriority 

    override init() { 
    } 

    init(title : String) { 
     self.title = title 
    } 

    func encodeWithCoder(aCoder: NSCoder) { 
     aCoder.encodeObject(title!, forKey: "title") 
     aCoder.encodeBool(checkmarked!, forKey: "checkmarked") 
     aCoder.encodeBool(isLastCell!, forKey: "isLastCell") 
     aCoder.encodeBool(enabled!, forKey: "enabled") 
    } 

    required init(coder aDecoder: NSCoder) { 
     title = aDecoder.decodeObjectForKey("title") as String! 
     checkmarked = aDecoder.decodeBoolForKey("checkmarked") as Bool 
     isLastCell = aDecoder.decodeBoolForKey("isLastCell") as Bool 
     enabled = aDecoder.decodeBoolForKey("enabled") as Bool 
    } 

}

Mam zamiar po prostu skopiować kod z projektem roboczym mam:

tutaj jest gra klasa obiektu z danymi z gry matematyczne kart flash:

import Foundation 

class GameData: NSObject { 

    var sign: String = "+" 
    var level: Int = 1 
    var problems: Int = 10 
    var time: Int = 30 
    var skipWrong: Bool = true 
    var usedTime: Int = 0 
    var correctCount: Int = 0 
    var correctTopNumber: [Int] = [Int]() 
    var correctBottomNumber: [Int] = [Int]() 
    var wrongTopNumber: [Int] = [Int]() 
    var wrongBottomNumber: [Int] = [Int]() 
    var date: NSDate = NSDate() 

    func encodeWithCoder(aCoder: NSCoder!) { 
     aCoder.encodeObject(sign, forKey: "sign") 
     aCoder.encodeInteger(level, forKey: "level") 
     aCoder.encodeInteger(problems, forKey: "problems") 
     aCoder.encodeInteger(time, forKey: "time") 
     aCoder.encodeBool(skipWrong, forKey: "skipWrong") 
     aCoder.encodeInteger(usedTime, forKey: "usedTime") 
     aCoder.encodeInteger(correctCount, forKey: "correctCount") 
     aCoder.encodeObject(correctTopNumber, forKey: "correctTopNumber") 
     aCoder.encodeObject(correctBottomNumber, forKey: "correctBottomNumber") 
     aCoder.encodeObject(wrongTopNumber, forKey: "wrongTopNumber") 
     aCoder.encodeObject(wrongBottomNumber, forKey: "wrongBottomNumber") 
     aCoder.encodeObject(date, forKey: "date") 
    } 

    init(coder aDecoder: NSCoder!) { 
     sign = aDecoder.decodeObjectForKey("sign") as String 
     level = aDecoder.decodeIntegerForKey("level") 
     problems = aDecoder.decodeIntegerForKey("problems") 
     time = aDecoder.decodeIntegerForKey("time") 
     skipWrong = aDecoder.decodeBoolForKey("skipWrong") 
     usedTime = aDecoder.decodeIntegerForKey("usedTime") 
     correctCount = aDecoder.decodeIntegerForKey("correctCount") 
     correctTopNumber = aDecoder.decodeObjectForKey("correctTopNumber") as Array 
     correctBottomNumber = aDecoder.decodeObjectForKey("correctBottomNumber") as Array 
     wrongTopNumber = aDecoder.decodeObjectForKey("wrongTopNumber") as Array 
     wrongBottomNumber = aDecoder.decodeObjectForKey("wrongBottomNumber") as Array 
     date = aDecoder.decodeObjectForKey("date") as NSDate 
    } 

    override init() { 
    } 
} 

Ta część wyglądem mniej więcej tak samo jak twoje, ale z bardziej zmiennymi typami. Klasy Archiver retriever i różnią się od siebie:

import Foundation 

class ArchiveGameData:NSObject { 

    var documentDirectories:NSArray = [] 
    var documentDirectory:String = "" 
    var path:String = "" 

    func ArchiveResults(#dataSet: [GameData]) { 
     documentDirectories = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) 
     documentDirectory = documentDirectories.objectAtIndex(0) as String 
     path = documentDirectory.stringByAppendingPathComponent("results3.archive") 

     if NSKeyedArchiver.archiveRootObject(dataSet, toFile: path) { 
      //println("Success writing to file!") 
     } else { 
      println("Unable to write to file!") 
     } 
    } 

    func RetrieveGameData() -> NSObject { 
     var dataToRetrieve = [GameData]() 
     documentDirectories = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) 
     documentDirectory = documentDirectories.objectAtIndex(0) as String 
     path = documentDirectory.stringByAppendingPathComponent("results3.archive") 
     if let dataToRetrieve2 = NSKeyedUnarchiver.unarchiveObjectWithFile(path) as? [GameData] { 
      dataToRetrieve = dataToRetrieve2 
     } 
     return(dataToRetrieve) 
    } 
} 

Wreszcie kod do przechowywania i pobierania z poziomu ViewController:

//retrieveing 
    var gameDataArray = ArchiveGameData().RetrieveGameData() as [GameData] 

//Archiving 
     gameData = GameData() //create local object then append all the new data, then store it 
gameData.sign = buttonStates.sign 
     gameData.level = buttonStates.level 
     gameData.problems = buttonStates.problems 
     gameData.time = buttonStates.time 
//etc. for all properties 

     ArchiveGameData().ArchiveResults(dataSet: gameDataArray)
