Ios – Can not remove push notification from notification center

cocoaiosobjective c

[[UIApplication sharedApplication] cancelAllLocalNotifications];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];'

I added the above code to didfinishLaunchingWithOptions but when a user taps a notification in his notification center and enters my app the notification does not gets cleared.

Edit:

I also tried adding this to my code:

You Also need to increment then decrement the badge in your
application:didReceiveRemoteNotification: method if you are trying
to clear the message from the message centre so that when a user
enters you app from pressing a notification the message centre will
also clear, ie:

[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];

as describes here: iOS application: how to clear notifications? but the notification still won't clear from the notification center

I just Added a Badge number manually to my application and pasted

- (void)applicationDidBecomeActive:(UIApplication *)application
{
      application.applicationIconBadgeNumber = 0;
}

To my AppDelegate. For me this works like a charm. Note that didfinishLaunchingWithOptions and applicationDidBecomeActive are not the same as Mouhammad Lamaa explained. If you paste this to your AppDelegate and tap the notification in notification center it should disapper. If it does not your App maybe creates a new Notification after becoming active?

Ios – Remove single remote notification from Notification Center

There is no way to remove a specific notification as of iOS SDK 5.0. The way to remove all the notifications from 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:

[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.

Ios – push notification handling

The wording here is confusing, especially around the word backgrounding.

When the application is truly not loaded in memory (e,g. when you launch it the splash screen shows up etc), then application:didFinishLaunchingWithOptions is called, and you can get the push notification as follows:

NSDictionary *remoteNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

if(remoteNotif)
{
    //Handle remote notification
}

If the app is loaded in memory and is ACTIVE (e.g. the app is currently open on the device) then only application:didReceiveRemoteNotification: is called.

If the app is loaded in memory but is not ACTIVE and NOT BACKGROUNDING (e.g., you launched the app, then pressed the home button, and waited 10 seconds), and then you click the action button on a push notification, only didReceiveRemoteNotification is called.

You can capture this case as follows:

-(void)application:(UIApplication *)app didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    if([app applicationState] == UIApplicationStateInactive)
    {
        //If the application state was inactive, this means the user pressed an action button
        // from a notification. 

    //Handle notification
    }
}
