打开其中一个后，所有通知都会消失 [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，让我们说我手机上有5个通知。如果我打开其中一个，其他所有通知都会消失。我只希望点击一个消失。

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.

这是我处理接收通知的方式：

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
}

推荐答案

通过设置 applicationIconBadgeNumber 到 0 ，您还会从通知中心删除所有通知。

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

这也是这里讨论：
iOS应用程序：如何清除不

此外，无法以编程方式删除单个通知，但是从iOS8开始，当用户点击时，操作系统会为您处理此问题一个通知。这也在这里讨论过：
从通知中心删除单个远程通知

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
