ios - specific - Repeating local notification daily at a set time with swift




uilocalnotification swift (3)

I am new to iOS development, but have created the app and I am trying to create a daily notification for a set time. Currently the notification executes once for the given date/time. I am unsure how to use the repeatInterval method to schedule it daily. What is the best method to repeat the notification daily ? any help would be much appreciated (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)

var repeatInterval: NSCalendarUnit

=> the docs say "The calendar interval at which to reschedule the notification."

so: use NSCalendarUnit.CalendarUnitDay


You have to provide an NSCalendarUnit value like “HourCalendarUnit” or “DayCalendarUnit” for repeating a notification.

Just add this code to repeat the local notification daily :

notification.repeatInterval = NSCalendarUnit.CalendarUnitDay

The other answers show how to use the old, pre iOS 10 local notifications. With iOS 10 and later, you must use UNNotificationCenter as follows:

    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
    })
