UInt8数组到Swift中的字符串

Question

我想将一个UInt8数组转换为几个字符串

var BytesArray = [123, 9, 32, 236]

至

var Srt0 = "123"
var Srt1 = "9"
var Srt2 = "32"
var Srt3 = "236"

Answer 1

你是说以下吗？

    var bytesArray = [123, 9, 32, 236]
    let stringArray = bytesArray.map( { "\($0)" })
    print(stringArray)

这将产生一个字符串数组。

Answer 2

var BytesArray: [Int] = [123, 9, 32, 236]

var stringArray = BytesArray.map
    {
        String($0)
}

stringArray将变为["123", "9", "32", "236"]

Answer 3

正如您所说，答案应该是这样的-

  var BytesArray = [123, 9, 32, 236]
  var sort0:String = String(BytesArray[0])
  var sort1:String = String(BytesArray[1])
  var sort2:String = String(BytesArray[2])
  var sort3:String = String(BytesArray[3])
