التاريخالهجري中的Hijri (伊斯兰)日历

Question

有人能帮帮我吗？

我正在尝试用Swift语言创建一个IOS应用程序，我需要使用Hijri (伊斯兰)日历

我试了很多次，但失败了。

这是我的尝试

    let datenow = NSDate()
    let calendar = NSCalendar.currentCalendar()
    let components = calendar.components(NSCalendarUnit(UInt.max), fromDate: datenow)

    var gregorian = NSCalendar(identifier:NSIslamicCivilCalendar)
    var date = gregorian.dateFromComponents(components)

    println(date)

输出是错误的

   2576-04-25 09:05:08 +0000

我们是在1434年，在hijri，而不是2576！

Answer 1

得到Hajri的约会日期：

Swift :

 let dateFor = DateFormatter()

 let hijriCalendar = Calendar.init(identifier: Calendar.Identifier.islamicCivil)
 dateFor.locale = Locale.init(identifier: "ar") // or "en" as you want to show numbers

 dateFor.calendar = hijriCalendar

 dateFor.dateFormat = "dd/MM/yyyy"
 print(dateFor.string(from: Date()))

Obj-C :

NSCalendar *hijriCalendar2 = [[NSCalendar alloc]initWithCalendarIdentifier:NSCalendarIdentifierIslamicCivil];
NSDateFormatter * lastDate = [[NSDateFormatter alloc]init];

lastDate.calendar = hijriCalendar2;
[lastDate setDateFormat:@"dd/MM/yyyy HH:mm:ss"];

NSString * dateString = [lastDate stringFromDate:[NSDate date]];

谢谢你@Grimxn和我也找到了一个展示阿拉伯数字的好方法

    let formatter = NSNumberFormatter()
    formatter.locale = NSLocale(localeIdentifier: "ar_SA")

    var date:String = "\(formatter.stringFromNumber(components.year))-\(formatter.stringFromNumber(components.month))-\(formatter.stringFromNumber(components.day))"

它将打印١-١١-١٤٣٤

Answer 3

Swift 3& 4

let dateNow = DateFormatter()
let islamicCalendar = Calendar.init(identifier: Calendar.Identifier.islamicCivil)
dateNow.calendar = islamicCalendar
dateNow.locale = Locale.init(identifier: "ar_SA") // This is used to show numbers, day and month in arabic letters
dateNow.dateFormat = "EEE dd MMM yyyy"

print("\(dateNow.string(from: Date()))")
