- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return [FBSession.activeSession handleOpenURL:url];
}

/*

{
    return [FBSession.activeSession handleOpenURL:url];
}
 */

/*
// this happens while we are running ( in the background, or from within our own app )

{
    if (!url) {

    }

    // calls into javascript global function 'handleOpenURL'
    NSString* jsString = [NSString stringWithFormat:@"handleOpenURL(\"%@\");", url];
    [self.viewController.webView stringByEvaluatingJavaScriptFromString:jsString];

    // all plugins will get the notification, and their handlers will be called
    [[NSNotificationCenter defaultCenter] postNotification:[NSNotification notificationWithName:CDVPluginHandleOpenURLNotification object:url]];

    return YES;
}
