我想保存一个在我的游戏中被称为果冻 bean 的分数。这些糖 bean 可以作为虚拟货币使用，因此在某些时候也会受到应用内购买的影响。
所以我的问题是最好的方法是什么。第一次玩游戏的玩家一开始的糖 bean 总数为 0。每次玩家升级，他们都会获得 10 颗糖 bean 。这些需要添加到总体虚拟货币中，以便可以使用。
如果玩家返回游戏，则应显示当前的糖 bean 总数，并且该总数将照常增加。
我的代码如图:

目前endGame()函数只是重置游戏，以后它会带你进入游戏结束场景。我希望您能提供帮助，如果您需要更多信息，请不要害怕询问。
最佳答案
NSUserDefaults 是保存游戏分数的正确工具。它允许您将数据保存在持久存储上。因此，下次用户运行您的游戏时，该数据将可用。
保存
var jellyBeanValue = 3
NSUserDefaults.standardUserDefaults().setInteger(3, forKey: "jellyBeanValue")
正在加载(即使应用程序重新启动后)
var jellyBeanValue = NSUserDefaults.standardUserDefaults().integerForKey("jellyBeanValue")
更多类型
您可以通过以下方法保存/加载其他类型的数据
func setBool(value: Bool, forKey defaultName: String)
func boolForKey(defaultName: String) -> Bool
func setFloat(value: Float, forKey defaultName: String)
func floatForKey(defaultName: String) -> Float
func setDouble(value: Double, forKey defaultName: String)
func doubleForKey(defaultName: String) -> Double
如果您需要保存可以使用的自定义类的实例
func setObject(value: AnyObject?, forKey defaultName: String)
func objectForKey(defaultName: String) -> AnyObject?
但在这种情况下，请查看 this .
iCloud
NSUserDefaults 将数据保存在设备的持久存储中。如果您想在用户使用特定 AppleID 登录的所有 Apple 设备之间同步数据，您应该使用 iCloud .
