我曾嘗試看看NSUserDefaults的關於其他的答案，但到目前爲止，他們並沒有幫助。爲NSUserDefaults的與其他自定義類變量的自定義對象
我試圖給玩家保存到NSUserDefaults的，但Player類還具有自定義類寵物小精靈和項目兩個變量。
如何保存和加載播放器？我是否需要分別編碼每個自定義類變量並解碼它們？我不確定它會如何工作。
這裏是我的課： Player類
import Foundation
class Player : NSCoder {
private var steps = Int()
private var money = Int()
private var items = [Item]()
private var pokemon = [Pokemon]()
var eggArray = [Int]()
struct User {
static var Gold = Player()
}
override init(){
steps = 0
money = 0
items = [Item]()
pokemon = [Pokemon]()
eggArray = [1, 4, 7, 10, 13, 16, 19, 21, 23, 27, 29, 32, 37, 41, 43, 43, 46, 48, 50, 52, 54, 56, 58, 60, 60, 63, 66, 69, 72, 74, 77, 79, 79, 81, 83, 84, 86, 88, 90, 92, 95, 96, 98, 100, 102, 104, 108, 109, 111, 113, 114, 115, 116, 118, 120, 122, 123, 127, 128, 129, 131, 133, 133, 133, 133, 133, 137, 138, 140, 142, 143, 147, 152, 155, 158, 161, 163, 165, 167, 170, 172, 173, 174, 175, 177, 179, 183, 185, 187, 190, 191, 193, 194, 198, 200, 201, 202, 203, 204, 206, 207, 209, 211, 213, 214, 215, 216, 218, 220, 222, 223, 225, 226, 227, 228, 231, 234, 235, 236, 236, 236, 238, 239, 240, 241, 246]
}
init(steps: Int, money: Int, items: [Item], pokemon: [Pokemon], eggArray: [Int]){
self.steps = steps
self.money = money
self.items = items
self.pokemon = pokemon
self.eggArray = eggArray
}
required convenience init(coder aDecoder: NSCoder) {
let steps = aDecoder.decodeIntegerForKey("steps")
let money = aDecoder.decodeIntegerForKey("money")
let items = aDecoder.decodeObjectForKey("items") as! [Item]
let pokemon = aDecoder.decodeObjectForKey("pokemon") as! [Pokemon]
let eggArray = aDecoder.decodeObjectForKey("eggArray") as! [Int]
self.init(steps: steps, money: money, items: items, pokemon: pokemon, eggArray: eggArray)
}
func encodeWithCoder(aCoder: NSCoder) {
aCoder.encodeInteger(steps, forKey: "steps")
aCoder.encodeInteger(money, forKey: "money")
aCoder.encodeObject(items, forKey: "items")
aCoder.encodeObject(pokemon, forKey: "pokemon")
aCoder.encodeObject(eggArray, forKey: "eggArray")
}
}
項目類
import Foundation
import CoreData
class Item : NSObject{
var name : String
var price : Int
init(item: NSManagedObject){
name = item.valueForKey("name") as! String
price = item.valueForKey("price") as! Int
super.init()
}
init(name: String, price: Int){
self.name = name
self.price = price
super.init()
}
}

，我使用調用保存和加載（僅用於測試） 有一個全局變量的兩個按鈕：var userDefaults = NSUserDefaults.standardUserDefaults()如果它很重要。
@IBAction func savePlayer(sender: UIButton) {
print("save")
userDefaults = NSUserDefaults.standardUserDefaults()
let encodedData = NSKeyedArchiver.archivedDataWithRootObject(Player.User.Gold)
userDefaults.setObject(encodedData, forKey: "player")
userDefaults.synchronize()
}
@IBAction func loadPlayer(sender: UIButton) {
print("load")
let decoded = userDefaults.objectForKey("player") as! NSData
let decodedPlayer = NSKeyedUnarchiver.unarchiveObjectWithData(decoded) as! Player
Player.User.Gold = decodedPlayer
}
現在我得到保存時的錯誤，我以爲是在節省Player類的項目，並口袋妖怪變量。
我想我明白了！我會亂它，看看它是否有效，只是怕編碼所有整個小寵物類 – mint
完美的作品！我被困在這個這麼久了，非常感謝你！ – mint
