ios - 如何清除应用中的远程通知？

Question

从 iPhone 屏幕顶部向下滑动时，是否可以清除通知横幅中的远程通知。我尝试将角标(Badge)编号设置为零:

application.applicationIconBadgeNumber = 0 

在委托(delegate) didFinishLaunchingWithOptions 和 didReceiveRemoteNotification 中，但它没有清除通知。谢谢。

Answer 1

在 iOS 10 中，上述所有解决方案都已弃用

'cancelAllLocalNotifications()' was deprecated in iOS 10.0: Use UserNotifications Framework's -[UNUserNotificationCenter removeAllPendingNotificationRequests]

使用下面的代码取消通知并重置角标(Badge)计数

对于 iOS 10，Swift 3.0

cancelAllLocalNotifications 已从 iOS 10 弃用。

@available(iOS, introduced: 4.0, deprecated: 10.0, message: "Use UserNotifications Framework's -[UNUserNotificationCenter removeAllPendingNotificationRequests]")
open func cancelAllLocalNotifications()

您必须添加此导入语句，

import UserNotifications

获取通知中心。并执行如下操作

application.applicationIconBadgeNumber = 0 // For Clear Badge Counts
let center = UNUserNotificationCenter.current()
center.removeAllDeliveredNotifications() // To remove all delivered notifications
center.removeAllPendingNotificationRequests() // To remove all pending notifications which are not delivered yet but scheduled.

如果您想删除单个或多个特定通知，可以通过以下方法实现。

center.removeDeliveredNotifications(withIdentifiers: ["your notification identifier"])

希望对您有所帮助..!
