Schedule a local notification on firing a local notification

Question

I want to schedule a local notification when my previous local notification gets fired. It should get scheduled disregarding the user taps 'View' or 'Cancel'.I am not getting proper place(delegate method)to schedule a new notification.According to Apple docs,application:(UIApplication *)application didFinishLaunchingWithOptions: can be used but it doesn't seems to be get called when application comes to foreground from background and application:(UIApplication *)application didReceiveLocalNotification: gets called only on click of 'View' and not on close.How should I do this?Any help is highly appreciated.

Yes. You are correct about the local notifications. You should click "view" to get the didReceiveLocalNotification: triggered. If you click "Cancel", you are not caring about the notificaiton. If you don't care, why should the iOS care? :-)

You are scheduling the notification. So, you know when it will be fired. Don't you? Then why wait for the first notification to be fired? Just schedule the second notification along with the first notification.

A workaround:

Local and Push Notification Programming Guide says that only 64 local notifications are allowed per app. So, schedule the first 64 notifications initially. And when the app opens the next time, check [UIApplication sharedApplication] scheduledLocalNotifications], and schedule the next (64 - scheduledLocalNotifications) notifications.

int scheduledNotifications = [UIApplication sharedApplication] scheduledLocalNotifications];  
int n = 64 - scheduledNotifications;  
[self Schedule-next-n-notifications];

Note: We can't guarantee that this will work perfectly. In case, if the app opens after very long gap, for example after 1 or 2 months, some notifications would have not been scheduled at the proper time.
