What is the code to remove the badge on my app's icon? When I receive push, I need to remove it when a button is clicked!
objC :
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
swift :
UIApplication.sharedApplication().applicationIconBadgeNumber = 0;
You can remove badge from push notifications by adding the following lines to your code
(void)applicationDidBecomeActive:(UIApplication *)application
{
[[UIApplication sharedApplication] cancelAllLocalNotifications];
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
}
As for iOS5, just setting badge number won't remove those push notification in the notification center. You have to do this...
[[UIApplication sharedApplication] cancelAllLocalNotifications];
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
I already tested this. It looks like cancelAllLocalNotifications
method also works with push notifications in notification center as well.
Swift 3
UIApplication.shared.applicationIconBadgeNumber = 0
Can be added to following methods:
optional public func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool
and
optional public func applicationDidBecomeActive(_ application: UIApplication)
