在swift中读取和访问多维数组

Question

我想声明一个数组，它应该是这样的:

myArray
  ->Car (Array)
    - Ford
    - Audi
    - ...
  ->Color (Array)
    - Red
    - Green
    - ...
  ->Wheels (Simple String, eg "4")
  ->Roof (Simple String, eg, "NO")

我在声明和访问这种类型的数组时被卡住了。谢谢你的帮助!

Answer 1

我认为创建自定义对象(带有类或结构)将更适合您，例如:

class Car {
    var brand: String?
    var color: String?
    var wheels: Int?
    init(brand: String, color: String, wheels: Int = 4) {
        self.brand = brand
        self.color = color
        self.wheels = wheels
    }
}
let myAudi = Car(brand: "Audi", color: "red")
let myFord = Car(brand: "Ford", color: "green", wheels: 3)
var myCars = [Car]()
myCars.append(myAudi)
myCars.append(myFord)
for aCar in myCars {
    println("My (aCar.brand!) is (aCar.color!) and has (aCar.wheels!) wheels.")
}

结果:

我的奥迪是红色的，有四个轮子。
我的福特是绿色的，有三个轮子。

Answer 2

你可以创建一个数组，每个元素作为一个数组。例如

var tempArr : [[String]] = [["Ford","Audi"],["Red","Green"],["4"],["NO"]]

根据你的问题，我猜你需要的是字典而不是数组

var tempDict : [String : [String]] = ["Car" : ["Ford","Audi"],.....]
