如何从Swift中的系统获取工作日数组？

我如何从系统中获取一个星期几的阵列（NSDate我想是from ）？

到目前为止，我只能参加当天的活动，但我希望能够安排多个工作日。

如果将一周的第一天设置为星期一，则我的数组将如下所示：

[ Mon, Tue, Wed... ]

如果一周的第一天是星期日，则我的数组如下所示：

[Sun, Mon, Tue... ]

代码：

let dateNow = NSDate()
let calendar = NSCalendar.currentCalendar()
let components = calendar.components(.CalendarUnitHour | .CalendarUnitMinute | .CalendarUnitSecond | .CalendarUnitYear , fromDate: dateNow) 

/*This is the way how i take system time */ 

let format = NSDateFormatter()
format.dateFormat = "EEE"
stringDay = format.stringFromDate(dateNow)

试试这些属性：

let fmt = NSDateFormatter()
fmt.weekdaySymbols // -> ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]
fmt.shortWeekdaySymbols // -> ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
fmt.veryShortWeekdaySymbols // -> ["S", "M", "T", "W", "T", "F", "S"]
fmt.standaloneWeekdaySymbols // -> ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"]
fmt.shortStandaloneWeekdaySymbols // -> ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
fmt.veryShortStandaloneWeekdaySymbols // -> ["S", "M", "T", "W", "T", "F", "S"]

似乎他们总是返回Sun ... Satarray而不管的.firstWeekday属性.calendar。因此，您必须手动旋转它。

let firstWeekday = 2 // -> Monday

var symbols = fmt.shortWeekdaySymbols
symbols = Array(symbols[firstWeekday-1..<symbols.count]) + symbols[0..<firstWeekday-1]
// -> ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
