Handling remote notifications when opening the app from the background?

[chrysb]

Hey guys,

There is no documentation on how to handle a remote notification when the application is running in the background (iOS4).

It seems like there is no way to know that the application entered the foreground from a remote notification.

Does anyone know more on the subject?

I would like to hear about that, too. My users are complaining that the icon badge never gets removed on their iOS 4 device - is this working as designed or a bug?

They have to close the app manually to get rid of the badge - is there something I can do to remove the badge, when the app goes to background?

Just set the badge to 0 in

- (void)applicationWillEnterForeground:(UIApplication *)application

Does anyone have any insight on this? It's ridiculous. You can't tell that the app entered the foreground via push/local notification.

Does anyone know if there are any developments on this front?

Has anyone shed any light on this?

I'm unclear about the problem. If you are handling the notification, doesn't that mean you are in the foreground?

If your app is in the background and you receive a push notification and the user taps "View", it brings the application to the foreground.

When that happens, only applicationDidEnterForeground is called, and there is no way to access the payload of the push notification.

Before multitasking, it would call applicationDidFinishLaunchingWithOptions and that would include the remote notification information.

Am I missing something here?

Only other relevant method I see is application: didReceiveRemoteNotification:

Yeah, and I verified, that does not get called when the app is in the background.

So, what I'm saying is, remote notifications don't work with multitasking, which is a mega, mega fail.

It's really broken our app :/

Thanks for taking a look, though!

You probably should post in the Apple developer forums.

I don't know if something isn't functioning as intended, but this Apple document:

Local and Push Notification Programming Guide


Says this:

In iOS, you can determine whether an application is launched as a result of the user tapping the action button or whether the notification was delivered to the already-running application by examining the application state. In the delegate’s implementation of the application:didReceiveRemoteNotification: or application:didReceiveLocalNotification: method, get the value of the applicationState property and evaluate it. If the value is UIApplicationStateInactive, the user tapped the action button; if the value is UIApplicationStateActive, the application was frontmost when it received the notification.

So, [UIApplication applicationState] is the important property. The document discusses payload, too.

I just tested on my 4.3.3 device, and application:didReceiveRemoteNotification most definitely is getting called for me.

I'm sorry for gravedigging this post.

I have the same problem proposed here:
- open app
- put it in background
- receive a remote notification
- tap on icon of the app
- nothing showing

IF i tap directly on the notification i get all working great, but if i tap on the app icon nothing will be shown about my notification.

Is there a solution to this? Thank you.

I really need this too. Bump. How can the app still register the notification even though the notificaton wasnt pressed?

[BrianSlick]

If the app was in the background at the time, and the user did not choose to view it within your app, then at next launch your app should talk to the server to find out about any missing notifications. It's not something the app can do alone.

Ok, got it. It introduces need for more server-side management, but it is probably healty anyways.
