UILocalNotification - How to handle when App is NOT running?

[thephatp]

I have implemented UILocalNotifications in two different apps now. One uses Location Services, which means if it gets killed, it (usually) gets restarted (so it's not as big of an issue). However, in another app, I schedule a UILocalNotification based upon time. In this case, I'm having a major problem.

If I schedule a notification, then the app gets killed, pushed out of memory, phone is turned off then on again, I cannot view older notifications "automatically" when opening the app.

Here is the workflow that works (app running in the background):

1. Launch app; app schedules notification; close app; app is now running in the background
2. Receive local notification; ignore it at first; pull the drop down menu from the top (status bar); touch the notification to launch the app
3. Results: The app appropriately displays the information in the notification.

Here is the workflow that does not work (app no longer running in the background):

1. Launch app; app schedules notification; close app; app is now running in the background
2. Manually kill app (to simulate my situation)
3. Still receive local notification; ignore it at first; pull the drop down menu from the top (status bar); touch the notification to launch the app
4. Results: The app launches, but the didReceiveLocalNotification method is not called. The user things the app doesn't work.
5. Note: I can't even manually force the information, because if they have received more than one notification, I can't tell which one they touched on to know which one to display.

Is there any way to know which notification they touched on when the app is not running in the background (and thus does not run the didReceiveLocalNotification method)?

UIApplication will call didFinishLaunchingWithOptions on your app delegate. In the options dictionary is a UILocalNotification object if it was launched due to that. You can retrieve it with the following key: UIApplicationLaunchOptionsLocalNotificationKey

I thought that was the correct way to do it, but it's still not working for some reason. I have the following code in my didFinishLaunchingWithOptions:

UILocalNotification *notification = 
    [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
[self application:application didReceiveLocalNotification:notification];

Is there something more I need to do? I seem to recall it not even calling the method, but I'll need to check again. Is it possible that I'm doing something incorrectly when scheduling the notification such that it wouldn't show up in this case (i.e. in the above code, "notification" turns out nil)?

Ok, I've done some testing and no luck.

At first, it worked. I almost reported back that somehow it was magically working again. I followed the steps outlined in my previous post, and when I touched one of the items in the notification center, it launched the app and showed the relevant information.

However, I did get it to not work again as well. The difference was that I performed the steps outlined in the original post, except this time, I wait a while (probably 30 minute) before touching one of the items in the notification center. This time, it launched the app, but it did not display the notification.

I don't know how to debug this in XCode, either, since I have to kill the app, which then kills the debugging. So, when I touch one of the notifications, I don't have an attached debugger when the app launches. I've created a UIView in code that contains a text field, and I'm outputting various details to that view and then showing the view. We'll see what happens now and if I can get a better idea as to what is going on when it doesn't work.

Any other ideas are welcome.
