iOS 11-用户本地通知，每x分钟重复一次 [英] iOS 11- User local notification which repeat every x minutes

问题描述

在iOS 11中，如何实现每隔x分钟重复一次的本地通知?

In iOS 11, how can I implement a local notification which repeats every x minutes?

将从用户中选择重复间隔.举例来说，假设用户选择设置一条通知，该通知将在明天的9:00 AM触发，并从那里每2天(或两周或6个月或10分钟)触发一次

The repeating interval will be selected from the user. So for example let's say that a user choose to set a notification which will trigger tomorrow at 9:00 AM and from there it triggers every 2 days (or two weeks or 6 months or 10 minutes)

var repeatInterval = Bool()

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

//Schedule the Notification
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)
    }
})
UNUserNotificationCenter.current().add(notificationRequest, withCompletionHandler: nil)

使用此代码，我可以在设定的日期安排通知.有人告诉我，从这里开始，如果我想安排重复通知，则应在传递通知时使用triggerInterval.但是我该怎么办呢?传递通知时，如何获取重复时间(由用户定义)的值?我可以用这个吗?:

With this code I can schedule a notification at a set date. I've been told that from here if I would like to schedule a repeat notification I should use a triggerInterval when the notification is delivered. But how can I do so? How can I get the value of the repeating time (defined by the user) when the notification is delivered? Shall I use this?:

func didReceive(_ notification: UNNotification)

我已经尝试过，但似乎从未有人打电话.

I've tried but it seems that it's never called.

我是新手，我已经尝试了很多次，但是似乎找不到解决方法.我已经能够管理每小时，每月，每天和每年的重复.如果我真的想添加自定义重复项，虽然我真的不知道该怎么做.

I'm new to swift and I've tried and tried but it seems I cannot find a solution. I've been able to manage the repeating hourly, monthly, daily and yearly. If I would like to add a custom repeat though I really wouldn't know how to do.

推荐答案

对于您的信息，您不能像每2分钟，10分钟或其他时间那样自定义重复时间间隔，必须使用

For your information you can't do customise repeat time interval like every 2 min, 10 min or Etc. you must use value of NSCalendarUnit like
