Question

我遇到Local Notification的问题，我有UIDatePicker来设置通知时间，还有ViewController来选择要重复通知的日期。如果我选择每个星期五重复一次，那将是行不通的，或者是另一天。但是，每天的通知运行良好。

我的代码：

func createRequestNotifications() {
    let content = UNMutableNotificationContent()
    content.title = "Time to learn"
    content.body = "Hey bro time to get some knolage)"
    content.sound = UNNotificationSound.default()

    let gregorian = Calendar(identifier: .gregorian)
    let now = Date()
    var components = gregorian.dateComponents([.year, .month, .day, .hour, .minute, .second], from: now)
    print(notification.day)
    components.hour = notifTime
    components.minute = notifMin
    components.second = 0
    components.day = notification.day
    components.weekdayOrdinal = 10
    components.timeZone = .current

    let date = gregorian.date(from: components)!

    if notification.day == 0 {
        let triggerDaily = Calendar.current.dateComponents([.hour,.minute,.second,], from: date)
        let trigger = UNCalendarNotificationTrigger(dateMatching: triggerDaily, repeats: true)
        let request = UNNotificationRequest(identifier: "any", content: content, trigger: trigger)
        UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
        print("evry day")
    } else {
        let triggerDaily = Calendar.current.dateComponents([.hour,.minute,.second, .day,], from: date)
        let trigger = UNCalendarNotificationTrigger(dateMatching: triggerDaily, repeats: true)
        let request = UNNotificationRequest(identifier: "any", content: content, trigger: trigger)
        UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
        print("date setup")
    }
}

notification.day

是从另一个ViewController设置的Int值，我选择在其中重复一天。

我很累，因为我不知道问题出在哪里，对于每个日期通知都有效，但是对于特殊的日子，：（

对于特定日期，您可以设置通知，请参阅以下链接 https://stackoverflow.com/a/46094544/5069429 根据您必须单独设置特定日期的通知您可以使用这样的功能

func setNotificationFor(weekday:Int,hour:Int,minute:Int,title:String,subTitle:String,body:String){
    let notification = UNMutableNotificationContent()
    notification.title = title
    notification.subtitle = subTitle
    notification.body = body


    var dateComponents = DateComponents()
    dateComponents.weekday = weekday  // 0,1,2,3,4,5,6
    dateComponents.hour = hour
    dateComponents.minute = minute
    let notificationTrigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)

    let request = UNNotificationRequest(identifier: "notification1", content: notification, trigger: notificationTrigger)
    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}
