使用swift在設定的時間每天重復本地通知

Question

我是iOS開發的新手，但已經創建了應用程序，我正在嘗試創建一段時間的每日通知。 目前，通知對於給定的日期/時間執行一次。 我不確定如何使用repeatInterval方法每天安排它。 每天重復通知的最佳方法是什么？ 任何幫助將不勝感激（Y）。

    var dateComp:NSDateComponents = NSDateComponents()
    dateComp.year = 2015;
    dateComp.month = 06;
    dateComp.day = 03;
    dateComp.hour = 12;
    dateComp.minute = 55;
    dateComp.timeZone = NSTimeZone.systemTimeZone()

    var calender:NSCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)!
    var date:NSDate = calender.dateFromComponents(dateComp)!

    var notification:UILocalNotification = UILocalNotification()
    notification.category = "Daily Quote"
    notification.alertBody = quoteBook.randomQuote()
    notification.fireDate = date
    notification.repeatInterval = 

    UIApplication.sharedApplication().scheduleLocalNotification(notification)

Answer 1

您必須提供NSCalendarUnit值，如“HourCalendarUnit”或“DayCalendarUnit”，以重復通知。

只需添加此代碼即可每天重復本地通知：

notification.repeatInterval = NSCalendarUnit.CalendarUnitDay

Answer 2

所以，不得不修改@ vizllx上面的代碼。 這是新行：

notification.repeatInterval = NSCalendarUnit.Day 

這是我使用的完整工作示例：

let notification = UILocalNotification()

  /* Time and timezone settings */
  notification.fireDate = NSDate(timeIntervalSinceNow: 8.0)
  notification.repeatInterval = NSCalendarUnit.Day
  notification.timeZone = NSCalendar.currentCalendar().timeZone
  notification.alertBody = "A new item is downloaded."

  /* Action settings */
  notification.hasAction = true
  notification.alertAction = "View"

  /* Badge settings */
  notification.applicationIconBadgeNumber =
  UIApplication.sharedApplication().applicationIconBadgeNumber + 1
  /* Additional information, user info */
  notification.userInfo = [
    "Key 1" : "Value 1",
    "Key 2" : "Value 2"
  ]

  /* Schedule the notification */
  UIApplication.sharedApplication().scheduleLocalNotification(notification)
}

Answer 3

var repeatInterval: NSCalendarUnit

=>文檔說“重新安排通知的日歷間隔”。

所以：使用NSCalendarUnit.CalendarUnitDay

Answer 4

其他答案顯示了如何使用舊的iOS 10之前的本地通知。 對於iOS 10及更高版本，您必須使用UNNotificationCenter，如下所示：

    let content = UNMutableNotificationContent()
    content.title = "This will appear in bold, on it's own line."
    content.subtitle = "This will appear in bold, on it's own line, below the title."
    content.body = "This will appear as normal text, below the title and subtitle."

    let triggerInputForHourlyRepeat = Calendar.current.dateComponents([.minute], from: intendedFireDateVariable)
    let trigger = UNCalendarNotificationTrigger.init(dateMatching: triggerInput, repeats: true)

    let request = UNNotificationRequest(identifier: "someUniqueID", content: content, trigger: trigger)
    let unc = UNUserNotificationCenter.current()
    unc.add(request, withCompletionHandler: { (error) in
        /// Handle error
    })
