NSCalendarUnit.Type可是沒有一個名爲CalendarUnitWeekDay

Question

let currentDayOfWeek = NSCalendar.currentCalendar().component(.CalendarUnitWeekday, fromDate: NSDate()) 

在這個地方成員，我得到一個錯誤：

NSCalendarUnit.Type doesnt have a member named CalendarUnitWeekDay

Answer 1

它不，它確實有Weekday，它可以以這種方式使用：

let calendar = NSCalendar.currentCalendar() 
let component = calendar.component(.Weekday, fromDate:NSDate())
