【问题描述】：

我正在尝试在我的应用程序中向本地通知添加徽章和声音，但我没有收到任何消息。 我看到通知应该出现但没有任何声音或徽章...... 谁能告诉我我做错了什么？

func requestUserPermissionForNotifications()
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge], completionHandler: didAllow, error in
        if (error != nil) 
            print("Error authorzing notifications")
         else 
            if (didAllow) 
                self.setDailyNotifications()
                print("User allowed to Push notifications")
             else 
                print("User did not allow to Push notifications")
            
        
    )


func setDailyNotifications() 
    var sunday = DateComponents()
    sunday.hour = 11
    sunday.minute = 00
    sunday.weekday = 1
    timeNotification(id: "Sunday", notificationTitle: "Daily reward is waiting", notificationText: "Log in and get your daily reward", timeOfNotification: sunday)


func timeNotification(id: String, notificationTitle: String, notificationText: String, timeOfNotification: DateComponents) 
    let trigger = UNCalendarNotificationTrigger(dateMatching: timeOfNotification, repeats: true)
    let content = UNMutableNotificationContent()
    content.title = notificationTitle
    content.body = notificationText
    content.sound = UNNotificationSound.default()
    content.badge = 1

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

    UNUserNotificationCenter.current().add(request)  (error) in
        if (error != nil) 
            print("Error adding notification \(id) --- \(String(describing: error))")
        
    

【问题讨论】：

您是否检查了设备上的设置？

我做了，声音和徽章是允许的。

【参考方案1】：

问题是我从 requestAuthorization() 方法调用了我的 setDailyNotifications() 函数。如果用户批准推送通知，我所做的只是从 viewDidLoad 调用 setDailyNotifications() 。
