＆＃39; DayCalendarUnit已弃用。请改用NSCalendarUnitDay＆＃39;不起作用

Question

let dateComponents = calendar.components(.DayCalendarUnit | .MonthCalendarUnit | .YearCalendarUnit, fromDate: date)  

我收到了错误：

'DayCalendarUnit' was deprecated in iOS version 8.0: Use NSCalendarUnitDay instead

但是当我用Apple建议的名称替换这些名字时

let dateComponents = calendar.components(NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear, fromDate: date)

我收到错误：

Use of unresolved identifier 'NSCalendarUnitDay' 

Answer 1

与最新的Swift 2.0一起：

svn

因此你现在将拥有：

NSCalendarUnit.Day

Answer 2

试试这个

NSCalendarUnit.CalendarUnitDay

Answer 3

最新的Swift仅适用于.day，.month等。
