如何选择数组Swift的元素

Question

我有一个这种格式的数组：

var array = [["one", "two", "three], ["four", "five", "six"], ["seven", "eight", "nine"]] 

那么，我如何选择例如＆＃34;四＆＃34;。

Answer 1

你去吧

let arrayOfArray:[[String]] = [["one", "two", "three"], ["four", "five", "six"], ["seven", "eight", "nine"]]
let middleArray = arrayOfArray[1]
let firstItem = middleArray[0]
let simplier = arrayOfArray[1][0]

结果在故事板中

Answer 2

变量array的类型为Array of Array of String

print(array[1]) //this will print second element of the array. which is ["four", "five", "six"]

并访问下面第二个索引中的第一个元素。

print(array[1][0]) // this will print your desire output. "four"
