Question

我正在尝试安排UILocalNotifications。我想要实现的功能是在特定的日子重复通知，例如（每个星期一）将由用户选择。有没有办法安排UILocalNotification，因此通知将仅在当天触发。

let notification = UILocalNotification()

let dict:NSDictionary = ["ID" : "your ID goes here"]
notification.userInfo = dict as! [String : String]
notification.alertBody = "\(title)"
notification.alertAction = "Open"
notification.fireDate = dateToFire
notification.repeatInterval = .Day  // Can be used to repeat the notification
notification.soundName = UILocalNotificationDefaultSoundName
UIApplication.sharedApplication().scheduleLocalNotification(notification)

Answer 1

通过以下方式每周进行一次：

notification.repeatInterval = .Weekday // Or maybe .WeekOfYear

无论一周中的哪一天dateToFire，通知都会在一周的那一天每周重复一次。

我不确定这会对你有所帮助，但我之前已经解决了这个问题。我创建了7个按钮，可以在一周内选择7天。这是我的旧代码：

class RemindNotification {

  var timerNotification = NSTimer()

  func notification(story: Story) {
    let calendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
    let date = NSDate()

    let dateComponents = calendar!.components([NSCalendarUnit.Day, NSCalendarUnit.WeekOfMonth, NSCalendarUnit.Month,NSCalendarUnit.Year,NSCalendarUnit.Hour,NSCalendarUnit.Minute], fromDate:date)
    dateComponents.hour = story.remindeAtHour
    dateComponents.minute = story.remindeAtMinute
    for index in 0..<story.remindeAtDaysOfWeek.count {
      if story.remindeAtDaysOfWeek[index] == true {
        if index != 6{
          dateComponents.weekday = index + 2
          fireNotification(calendar!, dateComponents: dateComponents)
        } else {
          dateComponents.weekday = 1
          fireNotification(calendar!, dateComponents: dateComponents)
        }
      } else {
        dateComponents.weekday = 0
      }
    }
  }

  func fireNotification(calendar: NSCalendar, dateComponents: NSDateComponents) {
    let notification = UILocalNotification()
    notification.alertAction = "Title"
    notification.alertBody = "It's time to take a photo"
    notification.repeatInterval = NSCalendarUnit.WeekOfYear
    notification.fireDate = calendar.dateFromComponents(dateComponents)
    UIApplication.sharedApplication().scheduleLocalNotification(notification)
  }
}

这是我的应用程序，我可以选择那一天，然后它可以在我每天设置的特定时间触发LocalNotification。

你可以参考它。希望这有帮助。
