使用未解析的标识符NSCalendarUnitDay [英] Use of unresolved identifier NSCalendarUnitDay

问题描述

我刚刚将Xcode更新到了6.3版本.

I just updated Xcode to its 6.3 version.

除了我必须针对as进行的所有修复(主要是)外，我还有一些警告刚刚出现(这很奇怪，因为它声明自iOS 8.0以来).

Except all the fixes I have to make regarding as (mainly), I have some warnings that just appeared (which is weird as it states it is since iOS 8.0).

我的代码

NSCalendar.currentCalendar().compareDate(self, toDate: date, toUnitGranularity: .DayCalendarUnit) == .OrderedAscending

现在显示警告

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

好，然后我将.DayCalendarUnit更改为NSCalendarUnitDay

现在我收到一条错误消息:

Now I get an error saying:

Use of unresolved identifier 'NSCalendarUnitDay'

我很困惑，有人可以向我解释哪里出了问题以及如何解决吗?

I'm confuse, can someone explain me what's wrong and how to fix it?

推荐答案

使用.CalendarUnitDay. NSCalendar是一个本机的Objective-C框架，错误消息并不迅速.

Use .CalendarUnitDay. NSCalendar is a native Objective-C framework and the error messages aren't for swift.
