如何设置 UserNotifications Framework 的通知 [英] How I can set a notification which UserNotifications Framework

问题描述

我可以在一个时间间隔内设置一个通知，但我不知道如何在特定的时间和日期设置它，我尝试了这个但不起作用

I can set a notification in a time interval but I don't know how make it in a specific time and date, I try this but don't work

let center = UNUserNotificationCenter.current()

func notificationSender(){

    center.requestAuthorization([.sound, .alert]) {
        (granted, error) in
        // We can register for remote notifications here too!
    }

    var date = DateComponents()
    date.hour = 13
    date.minute = 57

    let trigger = UNCalendarNotificationTrigger.init(dateMatching: date , repeats: false)

    let content = UNNotificationContent()
    // edit your content

    let notification = UNNotificationRequest(identifier: "myNotification", content: content, trigger: trigger)

center.add(通知)}

center.add(notification) }

每周一、周五下午3点需要重复通知

the notification need to be repeated every Monday and Friday at 3 pm

推荐答案

大功告成.留给你的事情不多了.

You're almost there. Not much left for you to do.

您缺少的内容如下:

• 您应该将 weekday 添加到您的日期组件中，1 用于星期日，因此在您的情况下，您需要将其设置为 2星期一通知和 6 星期五通知
• 如果需要重复，则需要在 UNCalendarNotificationTrigger 中将参数 repeas 设置为 true.

• You should add weekday to your date components, 1 is for Sunday so in your case you will need to set it to 2 for the Monday notification and 6 for your Friday notification
• If you need it to repeat you need to set the parameter repeats to true in your UNCalendarNotificationTrigger.

这是一个例子.

// Create date components that will match each Monday at 15:00
var dateComponents = DateComponents()
dateComponents.hour = 15
dateComponents.minute = 0
dateComponents.weekday = 2 // Monday

// Create a calendar trigger for our date compontents that will repeat
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents,
                                            repeats: true)

// Create the content for our notification
let content = UNMutableNotificationContent()
content.title = "Foobar"
content.body = "You will see this notification each monday at 15:00"

// Create the actual notification
let request = UNNotificationRequest(identifier: "foo",
                                    content: content,
                                    trigger: trigger)

// Add our notification to the notification center
UNUserNotificationCenter.current().add(request)
