【问题描述】：

您好，我正在尝试制作闹钟应用程序，我正在使用此帖子https://***.com/a/53902489 使用日程安排通知我已设置时间但一无所获，我想设置时间并提醒某些内容并在特定时间响铃

    scheduleNotification(at: createDate(date : 6, month : 2, hour: 17, minute: 15, year: 2019), identifierUnic: stringUUID(), body: "Notification day", titles: "Notification titles1")


      func createDate(date: Int, month : Int, hour: Int, minute: Int, year: Int)->Date 

            var components = DateComponents()
            components.hour = hour
            components.minute = minute
            components.year = year
            components.day = date
            components.month = month

            components.timeZone = .current

            let calendar = Calendar(identifier: .gregorian)
            return calendar.date(from: components)!
        


   func scheduleNotification(at date: Date, identifierUnic : String, body: String, titles:String) 
        let center = UNUserNotificationCenter.current()
        center.requestAuthorization(options: [.alert, .sound])  (granted, error) in 

         var anniversary = DateComponents()
        anniversary.day = 6
        anniversary.month = 2
        anniversary.hour = 5
        anniversary.minute = 44
        anniversary.second = 0

        let trigger = UNCalendarNotificationTrigger(dateMatching: anniversary, repeats: true)
        let content = UNMutableNotificationContent()
        content.title = titles
        content.body = body
        content.sound = UNNotificationSound.default
        content.categoryIdentifier = identifierUnic

        let request = UNNotificationRequest(identifier: identifierUnic, content: content, trigger: trigger)

        UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate

        UNUserNotificationCenter.current().add(request) (error) in
            if let error = error 
                print(" We had an error: \(error)")
            
    


      func registerLocal() 
            let center = UNUserNotificationCenter.current()

            center.requestAuthorization(options: [.alert, .badge, .sound])  (granted, error) in
                if granted 
                    print("Yay!")
                 else 
                    print("D'oh")
                
            
        

【参考方案1】：

您能否尝试为您的请求创建一个唯一的 ID，并在其中添加您的通知。

这是我的通知，对我来说效果很好

创建中心并检查授权

let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .sound]) 
    (granted, error) in

创建内容

let content = UNMutableNotificationContent()
content.title = "Title"
content.subtitle = "Subtitle."
content.body = "Body"

创建日期组件

var anniversary = DateComponents()
anniversary.day = 1
anniversary.month = 1
anniversary.hour = 12
anniversary.minute = 0
anniversary.second = 0

创建触发器

let trigger = UNCalendarNotificationTrigger(dateMatching: anniversary, repeats: true)

创建唯一 ID 并请求

let uuid = UUID().uuidString
let request = UNNotificationRequest(identifier: uuid, content: content, trigger: trigger)

将您的请求添加到中心并处理您的错误

center.add(request) 
    (error) in
   //Write your handle function here..
   //print(error) for example

希望对你有帮助……

【讨论】：

兄弟仍然无法工作我没有任何错误权限授予检查更新的代码

我不知道出了什么问题。是否有错误消息打印出来，或者构建成功并且应用程序没有发送通知？

app运行成功，没有报错，也没有及时通知

在 request.identifier 中预定但触发
