快速將int范圍數組轉換為字符串數組

Question

如何將范圍整數數組轉換為字符串數組？

像這樣的范圍int數組：

let data = [Array(1...9), Array(0...59), Array(0...59)]

像這樣的字符串數組：

let data = [["1", "2", "3",.....], ["0","1", "2", "3",...], ["0","1", "2", "3",...]]

Answer 1

嘗試這個

data.map{ $0.map(String.init) }

Answer 2

let data = [Array(1...9), Array(0...59), Array(0...59)]

var stringArray = Array<Array<String>>()

for array in data {
    var subArray = Array<String>()

    for item in array {
        subArray.append(String(item))
    }

    stringArray.append(subArray)
}

Answer 3

從數組中獲取值時，可以嘗試這樣。

代碼段：

let num = [1, 2, 3]
let data = [num, num, num]

let value = data[0]

for x in value {
    print(String(x))
}
