How can I differentiate between push notifications received in app and touched from outside the app?

Question

I have push notifications setup in my app. I have the method:

 - (void)application:(UIApplication *)application didReceiveRemoteNotification:     (NSDictionary *)userInfo
 {
      if()
      {
           //app is in foreground to get here
      }
      else if()
      {
           //app is in background and then the notification is clicked, to get here
      }
 }

I need to differentiate between touches of the notification outside the app, and simply receiving the notification in the app. Any help?

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    if ( application.applicationState == UIApplicationStateActive )
        // app was already in the foreground
    else
        // app was just brought from background to foreground
    ...
}
