In my app I am using uilocalnotifications. Every thing is ok but one thing. I need to show notifications's alertbody. If app is in foreground state it's fine, but if app is at background state and notification occurs, when i tap on that didReceiveLocalNotification doesn't get called. Obviously didFinishLaunchingWithOptions is also don't called at that time. So what should i do to handle the notification. I am using ios7 and xcode5. Thanks very much in advance if you could help me.

For an app which is not in the foreground, the local notification can subsequently be found in the

-applicationDidFinishLaunchingWithOptions method

UILocalNotification *localNotif =
        [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (localNotif) {
        //Handle local notification here.
    }

You can read Apple's documentation for handling notifications here.

If the app is currently in memory, you can check it's state in the following way:

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif
{
    if (app.applicationState == UIApplicationStateInactive )
    {
        NSLog(@"app not running");
    }
    else if(app.applicationState == UIApplicationStateActive )
    {
        NSLog(@"app running");
    }
}

    Thanks akashg for instant reply. But this method doesn't called. Because the app is already launched. – Muhammad Zeeshan Mar 14 '14 at 07:16
  • Check for further clarity here: http://stackoverflow.com/questions/4136333/test-if-app-did-become-active-from-a-uilocalnotification – ZeMoon Mar 14 '14 at 07:19
  • The answer with the maximum vote-ups on that page should help. – ZeMoon Mar 14 '14 at 07:23
  • I've checked but when i debug didReceiveLocalNotification doesn't get called as i mentioned in question. – Muhammad Zeeshan Mar 14 '14 at 07:29
  • Is this happening in iOS 6 as well? – ZeMoon Mar 14 '14 at 07:31
  • I don't know. But i am using ios7. I am debugging using breakpoints. When the app is at background state and notification is raised didReceiveLocalNotification doesn't call. – Muhammad Zeeshan Mar 14 '14 at 07:37
  • You need to check whether you app is in active state or not. if its in active state then simply return otherwise perform some action. if ( application.applicationState == UIApplicationStateActive ) { return; } else { //perform action } – PunjabiCoder Mar 14 '14 at 07:47
  • Please add some code related to your implementation of UILocalNotification – ZeMoon Mar 14 '14 at 07:49
  • Bundle of Thanks. I got it – Muhammad Zeeshan Mar 14 '14 at 11:50
  • Muhammad: How did you resolve this? I'm experiencing the same thing that `didReceiveLocalNotification:` is not called after the application wakes from inactive state. – Markus Rautopuro Aug 28 '14 at 16:44

    @MarkusRautopuro: see the first part of the answer. if app is killed and you tap on notification the '-applicationDidFinishLaunchingWithOptions' get called. otherwise 'didReceiveLocalNotification'. edited the answer. – nitish005 Apr 01 '16 at 13:04

if application is closed and notification is raised then for that you have to write below code in appdidfinishlaunching method

// Handle launching from a notification
    UILocalNotification *objLocalNotif =
    [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (objLocalNotif)
    {
        NSLog(@"At the time of launching Recieved Notification %@",objLocalNotif);
        //Do your stuff here
    }

If application is in background and when any local notification is raised the following method of app delegate get called.

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif {
    // Handle the notificaton when the app is running

    NSLog(@"Recieved Notification %@",notif);
    //do your stuff here
}

Write your code in the below method

- (void)applicationWillEnterForeground:(UIApplication *)application

it will be called when you open your application again which has not been terminated fully but still running in background
