Remove single remote notification from Notification Center
提问by MaTTP
my app receives remote notification from Apple server.
我的应用程序从 Apple 服务器接收远程通知。
Is there a way to remove a single remote notification from notification center (the drop-down menu available from iOs 5.0+), when the user taps on it?
当用户点击它时，有没有办法从通知中心（iOs 5.0+ 提供的下拉菜单）中删除单个远程通知？
Thanks!
谢谢！

There is no way to remove a specific notification as of iOS SDK 5.0. The way to remove all the notificationsfrom your app so they don't show in the Notification Center when the user opens the app from one of them, is to set the app badge to 0, like this:
从 iOS SDK 5.0 开始，无法删除特定通知。从您的应用程序中删除所有通知以便当用户从其中之一打开应用程序时它们不会显示在通知中心中的方法是将应用程序徽章设置为 0，如下所示：
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
EDIT: on iOS 8, SpringBoard seems to be automatically dismissing a notification when you tap on it on the Notification Center to open the app.
编辑：在 iOS 8 上，当您在通知中心点击它以打开应用程序时，SpringBoard 似乎会自动关闭通知。

Here is a suggestion, though it does have its flaws, and I haven't tried it myself:
这是一个建议，虽然它确实有缺陷，但我自己还没有尝试过：
- Push a silent notification (contentAvailable:true), don't include a "alert" inside the push, place the alert text in a custom property of the push
- Handle the incoming push and trigger a local notification, display it immediately
- If the user clicks the local notification, use the [UIApplication cancelLocalNotification:] which should remove the notification from the notification center.
- 推送无声通知（contentAvailable:true），推送中不要包含“alert”，将alert文本放在推送的自定义属性中
- 处理传入的推送并触发本地通知，立即显示
- 如果用户单击本地通知，请使用 [UIApplication cancelLocalNotification:] 从通知中心删除通知。

When you call the method:
[application cancelAllLocalNotifications];inside the AppDelegate methods:
当您调用该方法时：
[application cancelAllLocalNotifications];在 AppDelegate 方法中：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
and
和
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
