Hijri (islamic) calendar in swift التاريخ الهجري

How can I convert string date to NSDate?

我只是将它们放在一起，但输出有些错误。

let dateFormatter = NSDateFormatter()

dateFormatter.dateFormat = "YYYY-MM-DD"

let GregorianDate = dateFormatter.dateFromString("\(Yeartext1.text!)-\(Monthtext1.text!)-\(Daytext1.text!)")

let islamic = NSCalendar(identifier: NSIslamicCalendar)

let components = islamic?.components(NSCalendarUnit(rawValue: UInt.max), fromDate: GregorianDate!)

resultlable.text = "\(components!.year) - \(components!.month) - \(components!.day)"

例如，用户将输入格里高利日期（2015/09/29）并且应显示Hijri年份（1436/12/15），但这不起作用。

Answer 1

Yeartext1，Monthtext1和Monthtext1是UITextField

结果是UILabel

    let dateFormatter = NSDateFormatter()

    dateFormatter.dateFormat = "dd-MM-yyyy"

    let GregorianDate = dateFormatter.dateFromString("\(Daytext1.text!)-\(Monthtext1.text!)-\(Yeartext1.text!)")

    let islamic = NSCalendar(identifier: NSCalendarIdentifierIslamicUmmAlQura)

    let components = islamic?.components(NSCalendarUnit(rawValue: UInt.max), fromDate: GregorianDate!)

    resultlable.text = "\(components!.year) - \(components!.month) - \(components!.day)"

这将需要一个格里高利日期5-10-2015，它将给你伊斯兰日期1436 - 12 - 22

*一天错误的可能性很小

Answer 2

Hijri To Gregorian（这可以帮助某人）

let dateFormatter = NSDateFormatter()

dateFormatter.dateFormat = "dd-MM-yyyy"

dateFormatter.locale = NSLocale(localeIdentifier: "ar_SA")

let islamicDate = dateFormatter.dateFromString("8-10-1437")

let gregorian = NSCalendar(identifier: NSCalendarIdentifierGregorian)

let components = gregorian?.components(NSCalendarUnit(rawValue: UInt.max), fromDate: islamicDate!)

print("\(components!.year) - \(components!.month) - \(components!.day)")

将格里高利日期转换为Hijri日期
