Xcode 7:无法在Swift 2.0，Xcode 7中使用CalendarUnitMonth [英] Xcode 7: Can't use CalendarUnitMonth in Swift 2.0, Xcode 7

问题描述

我正在使用swift2.

I am using swift2.

我使用了以下代码:

let calendar = NSCalendar.currentCalendar()             
let components = calendar.components(.CalendarUnitMonth | .CalendarUnitDay, fromDate: theDate) 

我收到此错误:找不到成员'CalendarUnitMonth '

I am getting this error: Could not find member 'CalendarUnitMonth' 

推荐答案

检查Swift 2文档并搜索OptionSetType(由NSCalendarUnit采用).您可以通过以下方式使用它:

Check Swift 2 documentation and search for OptionSetType (adopted by NSCalendarUnit). You can use it in this way:

let calendar = NSCalendar.currentCalendar()
let components = calendar.components([.Month, .Day], fromDate:NSDate())
