我正在使用一个元组来存储这样的东西.
@H_403_2@var accessLavels: (hasInventoryAccess: Bool,hasPayrolAccess: Bool)
accessLavels = (hasInventoryAccess: true,hasPayrolAccess: false)
现在我想将它保存在NSUserDefaults中.
@H_403_2@NSUserDefaults.standardUserDefaults().setValue(accessLavels,forKey: "AccessLevelKey") NSUserDefaults.standardUserDefaults().synchronize()但是我收到以下错误.
类型'(hasInventoryAccess：Bool,hasPayrolAccess：Bool)’不符合协议’AnyObject’
我该如何解决这个问题？如果它不可能,那么欢迎任何其他保存元组的建议.
谢谢.
解决方法
我遇到了一个尝试用NSCoder编码元组的类似场景.我解决它的方法是手动将元组转换为字典.这不是一个很好的解决方案,因为如果元组发生变化,需要在几个地方更改密钥.
我的元组中有一个嵌套的枚举,并给它一个基本类型(String),我从中转换了原始值.这是一个额外的工作,但幸运的是你的只是原始人.
