Question

I’m trying to change the badge of the application I’m developing. When closed, unfortunately I was only notified a message without changing the badge.

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

[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeBadge];

NSDictionary* userInfo = [launchOptions valueForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"];
NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];

NSInteger badge = [[apsInfo objectForKey:@"badge"] integerValue];
if( [apsInfo objectForKey:@"alert"] != NULL)
{
    application.applicationIconBadgeNumber = badge;
}

But that does not change anything. I have not found any solution around. What method is invoked on arrival of a push notification and the application is closed? I also added:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

#if !TARGET_IPHONE_SIMULATOR

NSLog(@"remote notification: %@",[userInfo description]);
NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];

NSString *alert = [apsInfo objectForKey:@"alert"];
NSLog(@"Received Push Alert: %@", alert);

NSString *badge = [apsInfo objectForKey:@"badge"];
NSLog(@"Received Push Badge: %@", badge);
application.applicationIconBadgeNumber = [[apsInfo objectForKey:@"badge"] integerValue];

#endif
}

But nothing…

Can you help me?

You should define better what you want to do because it is not clear to me if wether you are talking about remote or local notifications, or what exactly you want to get and what are you getting.

Anyway, regarding remote notifications (APNS), take into account that you should set the badge as part of the payload if you want it to be set with the app closed. Your app does not get invoked unless the user manually opens the app (from the NotificationCenter or the dock).

On the other hand, when you are running the app, you will receive the call to

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

in your AppDelegate, and then you can set the badge by using

application.applicationIconBadgeNumber = badge;
