在SWIFT中將字符串拆分成數組？假設我這里有一根繩子：var fullName: String = "First Last"我希望將字符串拆分為空格，并將值賦值給它們各自的變量。var fullNameArr = // something like: fullName.explode(" ")
var firstName: String = fullNameArr[0]var lastName: String? = fullnameArr[1]而且，有時用戶可能沒有姓。

split
var fullName = "First Last"var fullNameArr = split(fullName) {$0 == " "}var firstName: String = fullNameArr[0]var lastName:
String? = fullNameArr.count > 1 ? fullNameArr[1] : nil.characters
let fullName = "First Last"let fullNameArr = fullName.characters.split{$0 == " "}.map(String.init)// or simply:
// let fullNameArr = fullName.characters.split{" "}.map(String.init)fullNameArr[0] // FirstfullNameArr[1] // Last

最簡單的方法是使用組件sSeparatedBy：
SWIFT 2：
import Foundationlet fullName : String = "First Last";let fullNameArr : [String] = fullName.componentsSeparatedByString(" ")
// And then to access the individual words:var firstName : String = fullNameArr[0]var lastName : String = fullNameArr[1]SWIFT 3：
import Foundationlet fullName : String = "First Last"let fullNameArr : [String] = fullName.components(separatedBy: " ") // And then to access the individual words:var firstName : String = fullNameArr[0]var lastName : String = fullNameArr[1]
