Notifications for LION and SnowLeopard

hey Mac Experts,

Am working on the new notification center for our app.
This works well for Mountain Lion.

I use the following code to ensure that notifications will only be triggered if the class exists.

 if (NSClassFromString(@"NSUserNotificationCenter") != nil)
      //Only Mountain Lion and Above
      NSUserNotification *userNotification = [NSUserNotification new];
      userNotification.title = title;
      userNotification.subtitle = subtitle;
      userNotification.informativeText = message;
      userNotification.userInfo = options;
      NSUserNotificationCenter *center = [NSUserNotificationCenter  defaultUserNotificationCenter];
      center.delegate = self;
      [center scheduleNotification:userNotification];
Now if i need to ensure that my executable will show notifications on LION and SnowLeopard, what are the best practises recommended?

I have set the Deployment target to 10.6
What do i do in the else part?

I could use GROWL SDK to provide notifications for LION, SL users.
But what if GROWL is not installed in the end user's system, then what are my options?

Can i display my notification as an Alert?
what are the best practises recommended?

Any responses will be appreciated.

The current Growl 2.0.1 SDK supports 10.6 thru 10.8 and will use the user notification center if it exists, otherwise it will use Growl if it is installed or Mist if not. Mist and the user notification center just don't have as many display or style options as Growl.

You can embed the Growl framework into your app.

IIRC, the notification will still show up even if the Growl app/PrefPane isn't installed, the user just can't edit the theme and some other prefs.
