单击时从通知中心删除通知 [英] Removing a notification from notification center on click

问题描述

是否可以在点击并启动应用程序时从通知中心删除推送通知?

Is it possible to remove the push notification from the notification center when one is clicked and the app launches?

大多数应用似乎都保留了通知.我在另一个问题上读到:

Most apps seem to leave the notification in place. I read on another question that this:

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]; 

可能有用，但对我不起作用.

may work however it doesn't work for me.

Facebook 应用似乎肯定会在点击后删除推送通知.

The Facebook app definitely seems to remove the push notifications once clicked on.

推荐答案

int badgeCount = [UIApplication sharedApplication].applicationIconBadgeNumber;
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeCount];

如果您将其添加到两者中

If you add this to both

- (void)applicationWillEnterForeground:(UIApplication *)application

和

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions (NSDictionary *)launchOptions

您将保留徽章计数，并在通知中心点击时清除推送通知.

You will retain the badge count, and clear the push notification when it is clicked in the notification center.
