推荐答案

这是一种印度式数字格式，其中100,000
（写成1， 00,000）是一个。

This is an indian style number format, where 100,000(written as 1,00,000) is one "lakh".

从给出：

let formatter = NSNumberFormatter()
formatter.numberStyle = .DecimalStyle
formatter.locale = NSLocale(localeIdentifier: "en_IN") // English (India) locale

let number = 12345678
let string = formatter.stringFromNumber(number)!
println(string) // 1,23,45,678

---

Swift 3更新：

let formatter = NumberFormatter()
formatter.numberStyle = .decimal
formatter.locale = Locale(identifier: "en_IN") // English (India) locale

let number = 12345678
let string = formatter.string(for: number)!
print(string) // 1,23,45,678
