ios - Clear Banner Notification When Tapped -

i have noticed when select push notification app notification center, notification no longer appears in list of notifications. however, when receive notification , tap banner right away, app opens should, when pull down view notification center, notification still there. have following push handling code in delegate:

- (void)application:(uiapplication *)application didreceiveremotenotification:(nsdictionary *)userinfo {      [[uiapplication sharedapplication] cancelalllocalnotifications];      //presenting view controllers...  }  - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     // override point customization after application launch.       // extract notification data     nsdictionary *notificationpayload = launchoptions[uiapplicationlaunchoptionsremotenotificationkey];      if(notificationpayload)     {         [[uiapplication sharedapplication] cancelalllocalnotifications];      }     return yes; }  - (void)applicationwillenterforeground:(uiapplication *)application {     // called part of transition background inactive state; here can undo many of changes made on entering background.      application.applicationiconbadgenumber = 0;     [[uiapplication sharedapplication] cancelalllocalnotifications]; }  -(void)application:(uiapplication *)application didreceivelocalnotification:(uilocalnotification *)notification {      // when tap on of notification delegate method call...     [[uiapplication sharedapplication] setapplicationiconbadgenumber:0];     [[uiapplication sharedapplication] cancellocalnotification:notification];  } 

you have use following remove notifications

- (void)applicationwillenterforeground:(uiapplication *)application     {         // called part of transition background active state; here can undo many of changes made on entering background.         [self clearnotifications];     }   - (void)applicationdidbecomeactive:(uiapplication *)application     {         // restart tasks paused (or not yet started) while application inactive. if application in background, optionally refresh user interface.         [self clearnotifications];     }  - (void)clearnotifications     {     [[uiapplication sharedapplication] setapplicationiconbadgenumber: 1];     [[uiapplication sharedapplication] setapplicationiconbadgenumber: 0];     [[uiapplication sharedapplication] cancelalllocalnotifications];     }
