Handling Push Notifications when App is NOT running

When your app is not running or killed and you tap on push notification this function will trigger;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

so you should handle it like this,

UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (localNotif) {
    NSString *json = [localNotif valueForKey:@"data"];
    // Parse your string to dictionary
}
