Swift UNUsernotification applicationIconBadgeNumber始终显示一个

问题描述:

我已设置用户通知。他们交付得很好,但应用程序图标上的徽章始终是一个。 这里是我的代码:Swift UNUsernotification applicationIconBadgeNumber始终显示一个

let center = UNUserNotificationCenter.current() 
let options: UNAuthorizationOptions = [.alert, .badge, .sound]; 

center.requestAuthorization(options: options) { 
     (granted, error) in 
     if !granted { 
      // ask for permission 
    } 
} 

当使用单击按钮我安排的通知符:

@IBAction func saveBtnPressed(sender: UIButton) { 
    scheduleNotif() 
} 

这里的scheduleNotif功能

func scheduleNotif() { 
    let dateformatter = DateFormatter() 
    dateformatter.dateStyle = DateFormatter.Style.medium 
    dateformatter.timeStyle = DateFormatter.Style.short 
    let dateFromString = dateformatter.date(from: selectDateTextField.text!) 
    let fireDateOfNotification: Date = dateFromString! 

    //Notif are enabled 
    let content = UNMutableNotificationContent() 
    content.title = notifTitleTextField.text! 
    content.body = notifNoteTextView.text 
    content.sound = UNNotificationSound.default() 
    content.badge = UIApplication.shared.applicationIconBadgeNumber + 1 as NSNumber 

    var trigger: UNCalendarNotificationTrigger 
    var triggerDate = DateComponents() 
    trigger = UNCalendarNotificationTrigger(dateMatching: triggerDate, repeats: false) 
    let titleNospace = notifTitleTextField.text?.replacingOccurrences(of: " ", with: "") 
    var 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) 
     } 
    }) 
} 

任何想法,为什么徽章将始终显示一个并且在通知交付时永不增加?

谢谢

这只是一个标签,而不是别的。 Apple不会为本地通知提供徽章自动增量。 – Mannopson

@Mannopson所以基本上没有办法增加标签,因为通知交付? – Marco

但是,您可以提供正确的值并将其设置为徽章。例如:'content.badge = deliveredNotifications.count'或类似的东西(只显示错过的通知数) – Mannopson

我认为你需要增加applicationIconBadgeNumber。所以更换

content.badge = UIApplication.shared.applicationIconBadgeNumber + 1 as NSNumber 

通过:

UIApplication.shared.applicationIconBadgeNumber += 1 
content.badge = UIApplication.shared.applicationIconBadgeNumber as NSNumber

如果你这样做,它会增加徽章,一旦预定。 ..而不是当它交付 – Marco
