将NSCalendarUnit转换为Swift2

Question

我有下面的代码：

var notification = UILocalNotification()
    notification.alertBody = "Message" // text that will be displayed in the notification
    notification.fireDate = NSDate()  // right now (when notification will be fired)
    notification.soundName = UILocalNotificationDefaultSoundName // play default sound

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

    notification.repeatInterval = NSCalendarUnit.CalendarUnitHour // this line defines the interval at which the notification will be repeated
    UIApplication.sharedApplication().scheduleLocalNotification(notification)

但它已被弃用。搜索了很多次，但无法将其转换为Swift2。有人能帮我解决这个问题吗：

notification.repeatInterval = NSCalendarUnit.CalendarUnitHour

Answer 1

Swift 2中的枚举比Objective-C中的要好得多。

尝试下一行：

notification.repeatInterval = NSCalendarUnit.Hour

它应该是有效的。
