打开其中一个后所有通知消失 [英] All notifications disappearing after opening one of them

问题描述

我有一个服务器向我发送推送通知，假设我的手机上有 5 个通知.如果我打开其中一个，所有其他通知都会消失.我只想点击一个消失.

这是我处理接收通知的方式:

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {if ( application.applicationState == UIApplicationState.Inactive || application.applicationState == UIApplicationState.Background ){//将用户导航到视图控制器}application.applicationIconBadgeNumber = 0}

解决方案

通过将 applicationIconBadgeNumber 设置为 0，您还可以从通知中心移除所有通知.

这里也讨论过这个:iOS 应用:如何清除通知?

此外，无法以编程方式删除单个通知，但从 iOS8 开始，当用户点击单个通知时，操作系统将为您处理此问题.这也在这里讨论过:从通知中心移除单个远程通知

I have a server that sends me push notifications and let's say that I have 5 notifications on my phone. If I open one of them all other notifications disappears. I want only the one clicked to disappear.

This is how I handle receiving notifications:

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {

    if ( application.applicationState == UIApplicationState.Inactive || application.applicationState == UIApplicationState.Background  )
    {
        // navigating user to a view controller
    }
    application.applicationIconBadgeNumber = 0
}

解决方案

By setting the applicationIconBadgeNumber to 0, you also remove every notification from the notification center.

This has also been discussed here: iOS application: how to clear notifications?

Furthermore, it is not possible to programmatically remove a single notification, but from iOS8 on, the OS will handle this for you when a user taps a single notification. This has also been discussed here: Remove single remote notification from Notification Center
