Question

我创建了一个结构来存储项目的字符串。

示例：

struct StringStruct {
     var BUTTON_TITLE: String = "Okay"
     var CANCEL_TITLE: String = "I don't think so"
     var DECLINE_TITLE: String = "No"
     var PROFILE_TABBAR_TITLE: String = "My Profile"
}

在应用程序中，我可以在某些时候更改这些变量。

我想知道我是否可以将所有值重置回初始状态？

Answer 1

重置StringStruct变量的最简单方法是分配一个新的默认值：

var strings = StringStruct()
strings.DECLINE_TITLE = "Nein"

strings = StringStruct()

如果您想将其作为（变异）函数，那么我会实现它是

struct StringStruct {
    var BUTTON_TITLE: String = "Okay"
    var CANCEL_TITLE: String = "I don't think so"
    var DECLINE_TITLE: String = "No"
    var PROFILE_TABBAR_TITLE: String = "My Profile"

    mutating func reset() {
        self = StringStruct()
    }
}

，无需重复所有默认值。

Answer 2

struct StringStruct {
     var BUTTON_TITLE: String = "Okay"
     var CANCEL_TITLE: String = "I don't think so"
     var DECLINE_TITLE: String = "No"
     var PROFILE_TABBAR_TITLE: String = "My Profile"

     mutating func reset() {
         BUTTON_TITLE = "Okay"
         CANCEL_TITLE = "I don't think so"
         DECLINE_TITLE = "No"
         PROFILE_TABBAR_TITLE = "My Profile"
     }
}
