【问题描述】：

如何在每 5 天上午 10:00 重复一次 LocalNotification

我尝试了这个，但它不起作用

let content = UNMutableNotificationContent()
content.title = "Hello!"
content.body = "Hello_message_body"
content.sound = UNNotificationSound.default()

let futureTime = Date().addingTimeInterval(5 * 24 * 60 * 60)
var calendar = NSCalendar.current
calendar.timeZone = NSTimeZone.system
var components = calendar.dateComponents([.hour, .minute, .second], from: futureTime)
components.hour = 10
components.minute = 0
components.second = 0

let trigger = UNCalendarNotificationTrigger(dateMatching: components, repeats: true)
let request = UNNotificationRequest(identifier: "FiveDays", content: content, trigger: trigger)
let center = UNUserNotificationCenter.current()
center.add(request)

【问题讨论】：

而不是计算futureTime，也许你应该使用DateComponents#day

请检查一下。 ***.com/questions/4363847/…

【参考方案1】：

您可以使用UNCalendarNotificationTrigger 获取本地通知，该通知在任何特定日期或星期的任何特定时间重复。

let notificationContent = UNMutableNotificationContent()
notificationContent.title = "Hello!"
//notificationContent.subtitle = "Something"
notificationContent.body = "Hello_message_body"
notificationContent.sound = UNNotificationSound.default

// Add notification for Friday (after 5 days) at 10:00 AM
var dateComponents = DateComponents()
dateComponents.weekday = 5
dateComponents.hour = 10
dateComponents.minute = 0

let notificationTrigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
let request = UNNotificationRequest(identifier: "notification1", content: notificationContent, trigger: notificationTrigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

谢谢。

嗨！，我正在使用相同的功能，但没有收到通知，甚至没有重复通知。
