Я пытался получить постоянные данные в своем приложении, чтобы иметь историю пользовательских записей. После того, как я храню свои данные в массиве, я хочу его заархивировать, и после того, как я его распакую, я получаю странное значение вместо того, что хочу видеть.Использование NSCore и NSKeyedArchiver с SWIFT
Вот мой класс для того, где я хранить мои данные
Foundation Импорт
class MyHistory: NSObject, NSCoding {
var kicksNumber: Int
var durationNumber: Int
init(kicksNumber: Int,durationNumber: Int) {
self.kicksNumber = kicksNumber
self.durationNumber = durationNumber
}
required init(coder decoder: NSCoder) {
kicksNumber = decoder.decodeObjectForKey("kicksNumber") as! Int
durationNumber = decoder.decodeObjectForKey("durationNumber") as! Int
}
func encodeWithCoder(coder: NSCoder) {
coder.encodeObject(self.kicksNumber, forKey: "kicksNumber")
coder.encodeObject(self.durationNumber, forKey: "durationNumber")
}
}
Тогда вот мой класс, где все происходит, и где я тестируя сохранение и процесс загрузки.
class Kicks: UIViewController {
var myHistoryArray: [MyHistory] = []
var currentMyHistory: MyHistory!
var newHistory = [MyHistory]()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.view.backgroundColor = UIColor(patternImage: UIImage(named: "background13.png")!)
let defaults = NSUserDefaults.standardUserDefaults()
if let savedPeople = defaults.objectForKey("MyHistory") as? NSData {
newHistory = NSKeyedUnarchiver.unarchiveObjectWithData(savedPeople) as! [MyHistory]
//print("this is archived ", newHistory[0])
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
var count = 0 as Int
var countKicks = 0 as Int
var kickReached = false as Bool
var pressedOnce = true as Bool
var timer = NSTimer()
var test: MyHistory!
@IBOutlet var timerLabel: UITextField!
@IBOutlet var kicksLabel: UITextField!
@IBAction func kickButton() {
//currentMyHistory.kicksNumber = 5
if pressedOnce {
pressedOnce = false
timer = NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: Selector("counter"), userInfo: nil, repeats: true)
} else if kickReached {
// let date = NSDate()
// let calendar = NSCalendar.currentCalendar()
// let timer_total = calendar.components([ .Hour, .Minute, .Second], fromDate: date)
} else if !pressedOnce {
countKicks++
kicksLabel.text = "\(countKicks)"
if countKicks == 10 {
kickReached = true
timer.invalidate()
congratsAlert()
currentMyHistory = MyHistory(kicksNumber: 5, durationNumber: 10)
print("this is currentMyHistory", currentMyHistory.kicksNumber)
myHistoryArray.append(currentMyHistory)
test = myHistoryArray[0]
print("this is myHistoryArray0", test.kicksNumber)
//save data
let savedData = NSKeyedArchiver.archivedDataWithRootObject(myHistoryArray)
let defaults = NSUserDefaults.standardUserDefaults()
defaults.setObject(savedData, forKey: "MyHistory")
//load data
//let defaults = NSUserDefaults.standardUserDefaults()
// let person = people[indexPath.item]

print("this is unrachived",newHistory[0])
clear()
}
}
}
// save countKicks, count, and stamp i
func congratsAlert() {
let alert = UIAlertController(title: "Congratulation", message: "Yay!!! Angelina kicked 10 times in less than 2 hours.",preferredStyle: .Alert)
let okAction = UIAlertAction(title: "Ok",style: .Default,handler:{(action:UIAlertAction) -> Void in})
alert.addAction(okAction)
presentViewController(alert,animated: true,completion: nil)
}
func clear() {
count = 0
countKicks = 0
kickReached = false
pressedOnce = true
timerLabel.text = "00:00:0\(count)"
kicksLabel.text = "\(countKicks)"
}
func counter() {
++count
let (hour,minutes,seconds) = secondsToHoursMinutesSeconds(count)
if seconds < 10 && minutes < 10 {
timerLabel.text = "0\(hour):0\(minutes):0\(seconds)"
} else if seconds > 9 && minutes < 10 {
timerLabel.text = "0\(hour):0\(minutes):\(seconds)"
} else if seconds > 9 && minutes > 9 {

} else if seconds < 10 && minutes > 9 {

}
}
func secondsToHoursMinutesSeconds (seconds : Int) -> (Int, Int, Int) {
return (seconds/3600, (seconds % 3600)/60, (seconds % 3600) % 60)
}
/*

}

}
}*/
}
Мой выход, как это:
это currentMyHistory 5
это myHistoryArray0 5
это unrachived

Почему unarchived странно стоимость?
