Ios UILocalNotification每周重复一次

我想设置一个

UILocalNotification

，它将在每个星期五自动重复一次。我目前正在使用下面的代码在同一时间每天重复一次通知，但我不知道如何为本周创建此通知

多谢各位

let calendar: NSCalendar! = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
                let now: NSDate! = NSDate()
                let notifDate = calendar.dateBySettingHour(19, minute: 0, second: 0, ofDate: now, options: NSCalendarOptions.MatchFirst)!

                var notification = UILocalNotification()
                notification.category = "Reminder"
                notification.alertTitle = "Alert"
                notification.alertBody = "Alert body"
                notification.fireDate = notifDate
                notification.soundName = UILocalNotificationDefaultSoundName
                notification.repeatInterval = NSCalendarUnit.Day
                UIApplication.sharedApplication().scheduleLocalNotification(notification)

检查这里的UILocalNotification

这是您将其设置为每周重复的方式

notification.repeatInterval = NSCalendarUnit.WeekOfYear;

注：此代码将在创建notif的当天创建notif，而不仅仅是在周五。需要考虑的事情p>

let now: NSDate! = NSDate() //whatever today's day is and it could be any day between M-Sun
let notifDate = calendar.dateBySettingHour(19, minute: 0, second: 0, ofDate: now, options: NSCalendarOptions.MatchFirst)!

将repeatInterval更改为NSCalendarUnit。一年中的一周。它将在每周的同一时间重复。似乎没有“NSCalendarUnit.week”。当使用有关错误消息的行更改为：使用未解析标识符“kCFCalendarUnitWeek”Try-NSWeekCalendarUnit时，出现一个错误，该错误表示：类型“NSCalendarUnit”没有成员“Week”或“NSCalendarUnit.WeekOfYear”
