我正在收到'NSCalendar？'自XCode版本6.1（6A1052d）更新以来没有名为'components'的成员错误

Question

此更新为我打破了几件事。

以下是代码：

func convertStartAndExpiryDateFromPickerIntoString(datePicker: UIDatePicker) -> String {
    let dateFromPicker = datePicker.date
    let calendar = NSCalendar(calendarIdentifier: NSGregorianCalendar)
    let unitFlags = NSCalendarUnit.MonthCalendarUnit | NSCalendarUnit.DayCalendarUnit
    let components = calendar.components(unitFlags, fromDate: dateFromPicker)
    return "\(months.objectAtIndex(components.month)) \(components.day)"

}

有什么想法吗？

感谢您的时间

罗布建议工作时解开。

func convertStartAndExpiryDateFromPickerIntoString(datePicker: UIDatePicker) -> String {
        let dateFromPicker = datePicker.date
        let calendar = NSCalendar(calendarIdentifier: NSGregorianCalendar)!
        let unitFlags = NSCalendarUnit.MonthCalendarUnit | NSCalendarUnit.DayCalendarUnit
        let components = calendar.components(unitFlags, fromDate: dateFromPicker)
        return "\(months.objectAtIndex(components.month)) \(components.day)"

    }
