用户选择的swift 3重复间隔中的本地通知-Java 学习之路

我正在尝试编写一些代码，允许用户设置自定义本地通知以提醒他们一些任务 . 我正在使用用户通知框架 . 因此，基本上用户可以决定设置通知，提醒他每周购买一些肥皂或每年生日祝福或每个月检查一些东西（这些只是示例） .

到目前为止，我已经能够设置一个没有重复间隔的本地通知 .

func scheduleNotif() {
    let dateformatter = DateFormatter()
    dateformatter.dateStyle = DateFormatter.Style.medium
    dateformatter.timeStyle = DateFormatter.Style.short
    let dateFromString = dateformatter.date(from: selectDateTextField.text!)
    let fireDateOfNotification: Date = dateFromString!

    //if notif are allowed
    let content = UNMutableNotificationContent()
    content.title = notifTitleTextField.text!
    content.body = notifNoteTextView.text
    content.sound = UNNotificationSound.default()
    content.badge = UIApplication.shared.applicationIconBadgeNumber + 1 as NSNumber

    let triggerDate = Calendar.current.dateComponents([.year,.month,.day,.hour,.minute,.second,], from: fireDateOfNotification)
    let trigger = UNCalendarNotificationTrigger(dateMatching: triggerDate,
                                                repeats: false)
    //Schedule the Notification
    let titleNospace = notifTitleTextField.text?.replacingOccurrences(of: " ", with: "")
    let identifier = titleNospace
    let request = UNNotificationRequest(identifier: identifier!, content: content, trigger: trigger)
    self.center.add(request, withCompletionHandler: { (error) in
        if let error = error {
            print(error.localizedDescription)
        }
    })
}

日期是从日期选择器中选取的 . 现在从另一个选择器我希望用户选择重复间隔（无，每天，每周，每月，每年和特定日期） . 我不确定如何实现这一目标 . 我是否需要使用if else if语句？（这对我来说似乎不太正确 . ）有没有更好的方法来实现这一目标？谢谢！

目前我已经用这种方式修复了它：

let dateformatter = DateFormatter()
dateformatter.dateStyle = .medium
dateformatter.timeStyle = .short
let dateFromString = dateformatter.date(from: selectDateTextField.text!)
let fireDateOfNotification: Date = dateFromString!

var trigger: UNCalendarNotificationTrigger
var triggerDate: DateComponents
var repeatInterval = Bool()

if repeatingInterval == "Hourly" {
    triggerDate = Calendar.current.dateComponents([.minute], from: fireDateOfNotification)
    repeatInterval = true
} else if repeatingInterval == "Daily" {
    triggerDate = Calendar.current.dateComponents([.hour, .minute], from: fireDateOfNotification)
    repeatInterval = true
} else if repeatingInterval == "Weekly" {
    triggerDate = Calendar.current.dateComponents([.weekday, .hour, .minute], from: fireDateOfNotification)
    repeatInterval = true
} else if repeatingInterval == "Monthly" {
    triggerDate = Calendar.current.dateComponents([.day, .hour, .minute], from: fireDateOfNotification)
    repeatInterval = true
} else if repeatingInterval == "Yearly" {
    triggerDate = Calendar.current.dateComponents([.month, .day, .hour, .minute], from: fireDateOfNotification)
    repeatInterval = true
} else {
    triggerDate = Calendar.current.dateComponents([.year,.month,.day,.hour,.minute,.second,], from: fireDateOfNotification)
    repeatInterval = false
}

trigger = UNCalendarNotificationTrigger(dateMatching: triggerDate, repeats: repeatInterval)

//Schedule the Notification
......

还没有找到一种方法来安排不同的时间间隔（例如每两周，每隔一天，每六个月等） . 我仍然会研究它 . :)
