保存和加载NSNumber(Saving and Loading NSNumber)

 我在BlackJack游戏上工作，我很难找到使用NSNumbers和NSUserDefaults保存和加载名为PlayerMoney的int的正确方法。 
 
 这是我试图加载值的方式 
 
-(void)createSceneContents {


    //Load ---------------------------------------------------------
    NSUserDefaults *Defaults = [NSUserDefaults standardUserDefaults];
    NSNumber *PlayerMoneyLoad = [Defaults objectForKey:@"PlayerMoneySave"];
    self.PlayerMoney = PlayerMoneyLoad;
    NSLog(@"PlayerMoneyLoad:%@", PlayerMoneyLoad);
    NSLog(@"PlayerMoney:%@", self.PlayerMoney);
 
 这是我试图保存它的地方 
 
    //Save ---------------------------------------------------------
    NSUserDefaults *Defaults = [NSUserDefaults standardUserDefaults];
    NSNumber *PlayerMoneySave = [NSNumber numberWithInt:self.PlayerMoney];
    [Defaults setObject:PlayerMoneySave forKey:@"PlayerMoneySave"];
    [Defaults synchronize];
 
 在我添加线之前 
 
    self.PlayerMoney = PlayerMoneyLoad;
 
 保存工作正常但在加载游戏时，“NSNumber PlayerMoneyLoad”不会将值传输到“int PlayerMoney”。 现在我已经添加了这一行，当游戏保存时，似乎在150000000左右选择一个随机数，任何帮助都是值得赞赏的。 

Im working on a BlackJack game and I'm having trouble finding the correct way of saving and loading an int named PlayerMoney using NSNumbers and NSUserDefaults.
 
Here is how Im trying to load the Values
 
-(void)createSceneContents {


    //Load ---------------------------------------------------------
    NSUserDefaults *Defaults = [NSUserDefaults standardUserDefaults];
    NSNumber *PlayerMoneyLoad = [Defaults objectForKey:@"PlayerMoneySave"];
    self.PlayerMoney = PlayerMoneyLoad;
    NSLog(@"PlayerMoneyLoad:%@", PlayerMoneyLoad);
    NSLog(@"PlayerMoney:%@", self.PlayerMoney);
 
and here is where I try to save it
 
    //Save ---------------------------------------------------------
    NSUserDefaults *Defaults = [NSUserDefaults standardUserDefaults];
    NSNumber *PlayerMoneySave = [NSNumber numberWithInt:self.PlayerMoney];
    [Defaults setObject:PlayerMoneySave forKey:@"PlayerMoneySave"];
    [Defaults synchronize];
 
before I added the line
 
    self.PlayerMoney = PlayerMoneyLoad;
 
Saving was working but upon loading the game the "NSNumber PlayerMoneyLoad" would not transfer the value to the "int PlayerMoney". Now that I've added this line, when the game saves it seems to pick a random number somewhere around 150000000 any help is appreciated.
