How to Remove Push Notification in Notification Center after viewed - ios

Question

Is there any way to handle the push notification from the Notification Center after being tap, and remove it when my application has already launched?

I know this is hack and slash, but you can clear all notifications by changing the badge number on your application.
- (void)application:(UIApplication*)application didReceiveRemoteNotification (NSDictionary*)payload
{
NSLog(#"Received notification: %#", payload);
//swapping between two badge numbers to clear notifications
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
...
}
If you already had a badge number you don't want to lose (above example will simply clear badge number in the end) you can do something like
- (void)application:(UIApplication*)application didReceiveRemoteNotification (NSDictionary*)payload
{
NSLog(#"Received notification: %#", payload);
/*
storing current badge number then swapping between 2 values to make sure we
clear the badge number. Once this is done set badge number back to original
value.
*/
int badgeNum = [[UIApplication sharedApplication] applicationIconBadgeNumber]
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeNum];
...
}
This may not be best practice, but it gets the job done and the client will not know the difference. I like to call it a temp. fix until I stumble upon a better solution. Hope this helps someone!
