If application is in background state and launch on locanotification tap Which methods called in appdelegate

Question

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.

Answer 1

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");
    }
}

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
}

Answer 3

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
