Struct 结构体

介绍

结构体类似 js 中的类，可实例化，内部可以定义变量和方法。

官方文档参考结构和类。

例子

struct Student {
  static let tableName = "表格名称"

  var name = ""
  var age: Int? = nil
  var chinese: Int? = nil
  var math: Int? = nil
  var total: Int? = nil

  mutating func conputed() {
    self.total = self.chinese! + self.math!
  }
}

var zhangSan = Student(name: "张三", age: 12, chinese: 10, math: 20)

zhangSan.conputed()

print(zhangSan)
