快速回历（伊斯兰）日历التاريخالهجري

您正在混合日历，日期和组成部分：

let datenow = NSDate()     // This is a point in time, independent of calendarslet calendar = NSCalendar.currentCalendar()     // System calendar, likely Gregorian let components = calendar.components(NSCalendarUnit(UInt.max), fromDate: datenow)     // Gregorian componentsprintln("(components.year)") // "2014"var islamic = NSCalendar(identifier:NSIslamicCivilCalendar)! // Changed the variable name     // *** Note also NSCalendar(identifier:) now returns now returns an optional ***var date = islamic.dateFromComponents(components)     // so you have asked to initialise the date as AH 2014println(date)     // This is a point in time again, sometime in AH 2014, or AD 2576

您需要做的只是：

let datenow = NSDate()let islamic = NSCalendar(identifier:NSIslamicCivilCalendar)!let components = islamic.components(NSCalendarUnit(UInt.max), fromDate: datenow)println("Date in system calendar:(datenow), in Hijri:(components.year)-(components.month)-(components.day)")   //"Date in system calendar:2014-09-25 09:53:00 +0000, in Hijri:1435-11-30"

要获取格式化的字符串，而不仅仅是整数部分，您需要使用

NSDateFormatter

，这将允许您指定日历和日期以及格式。看这里。

可以根据要求将数字简单地音译为（东方）阿拉伯数字（因为0
… 9被称为（西方）阿拉伯数字，以区别于罗马数字），您可以使用：

let sWesternArabic = "(components.day)-(components.month)-(components.year)"let substituteEasternArabic = ["0":"٠", "1":"١", "2":"٢", "3":"٣", "4":"٤", "5":"٥", "6":"٦", "7":"٧", "8":"٨", "9":"٩"]var sEasternArabic =  ""for i in sWesternArabic {    if let subs = substituteEasternArabic[String(i)] { // String(i) needed as i is a character        sEasternArabic += subs    } else {        sEasternArabic += String(i)    }}println("Western Arabic numerals = (sWesternArabic), Eastern Arabic numerals = (sEasternArabic)")
