Yes you can find application launching reason in

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

// keys can be UIApplicationLaunchOptionsLocalNotificationKey

NSDictionary *notificationPayload = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
if(notificationPayload)
{
    // application launch because of notification
    // do some stuff here
}

return YES;

}
