将代码从 swift 更改为 swift 2.0 [重复]

Question

我想将我的 swift 代码更改为 swift 2.0 我希望你能帮助我。

                let calendar = NSCalendar.currentCalendar()
            let components = calendar.components(.CalendarUnitYear | .CalendarUnitMonth | .CalendarUnitDay , fromDate:  notification.fireDate!)
            var gregorian:NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)!
            let unit: NSCalendarUnit = .CalendarUnitHour | .CalendarUnitMinute
            var comps:NSDateComponents = gregorian.components(unit, fromDate: timepicker.date)


            comps.setValue(components.day, forComponent: NSCalendarUnit.CalendarUnitDay)
            comps.setValue(components.month, forComponent: NSCalendarUnit.CalendarUnitMonth)
            comps.setValue(components.year, forComponent: NSCalendarUnit.CalendarUnitYear)
            comps.setValue(comps.hour, forComponent: NSCalendarUnit.CalendarUnitHour)
            comps.setValue(comps.minute, forComponent: NSCalendarUnit.CalendarUnitMinute)
            var NewFiredate : NSDate = gregorian.dateFromComponents(comps)!

在我的这部分代码中，我收到以下错误：

• 找不到成员“CalendarUnitYear”
• 找不到成员“CalendarUnitHour”
• “NSCalendarUnit.Type”没有名为“CalendarUnitHour”的成员
• “NSCalendarUnit.Type”没有名为“CalendarUnitMinute”的成员

非常感谢:)

您可以使用下面的代码，基本上我用新的 OptionSetType 语法替换了枚举，并进行了一些小的更改。 NSCalendarUnit OptionSetType 有这些你可以使用的静态类型，

static var Era: NSCalendarUnit { get }
static var Year: NSCalendarUnit { get }
static var Month: NSCalendarUnit { get }
static var Day: NSCalendarUnit { get }
static var Hour: NSCalendarUnit { get }
static var Minute: NSCalendarUnit { get }
static var Second: NSCalendarUnit { get }
static var Weekday: NSCalendarUnit { get }
static var WeekdayOrdinal: NSCalendarUnit { get }
static var Quarter: NSCalendarUnit { get }
static var WeekOfMonth: NSCalendarUnit { get }
static var WeekOfYear: NSCalendarUnit { get }
static var YearForWeekOfYear: NSCalendarUnit { get }
static var Nanosecond: NSCalendarUnit { get }
static var Calendar: NSCalendarUnit { get }
static var TimeZone: NSCalendarUnit { get }

所以，你的新代码应该是这样的，

let calendar = NSCalendar.currentCalendar()
let components = calendar.components([.Year, .Month, .Day] , fromDate:  notification.fireDate!)
var gregorian:NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)!
let unit: NSCalendarUnit = [.Hour, .Minute]
var comps:NSDateComponents = gregorian.components(unit, fromDate: timepicker.date)


comps.setValue(components.day, forComponent:.Day)
comps.setValue(components.month, forComponent:.Month)
comps.setValue(components.year, forComponent:.Year)
comps.setValue(comps.hour, forComponent:.Hour)
comps.setValue(comps.minute, forComponent:.Minute)
var NewFiredate : NSDate = gregorian.dateFromComponents(comps)!
