How do I customize a UIActivityViewController to show a URL link when posting to facebook and twitter?

Question

So I\'m trying out the new UIActivityViewController in iOS 6, and it\'s really easy to get up and running, but I can\'t figure out how to control it like I want

If you don't specifically need to use UIActivityViewController using SLComposeViewController is easy to use for this purpose.

+(void)presentShareWidgetWithText:(NSString*)text url:(NSURL*)url images:(NSArray*)images toService:(NSString*)service presentIn:(UIViewController*)parentViewController {
    SLComposeViewController* controller = [SLComposeViewController composeViewControllerForServiceType:service];
    if (controller == nil) {
        DLog(@"Could not initialize SLComposeViewController for %@!", service);
        return;
    }
    if (url != nil) {
        if (![controller addURL:url])
            DLog(@"Failed adding url %@!", url);
    }
    if (images != nil) {
        for (UIImage* image in images) {
            if (![controller addImage:image]) {
                DLog(@"Failed adding image: %@", image);
            }
        }
    }
    if (![controller setInitialText:text]) {
        DLog(@"Failed setting initial text: %@", text);
    }

    SLComposeViewControllerCompletionHandler handler = ^(SLComposeViewControllerResult result) {
        switch (result) {
            case SLComposeViewControllerResultCancelled:
                DLog(@"SLComposeViewControllerResultCancelled");
                break;

            case SLComposeViewControllerResultDone:
                DLog(@"SLComposeViewControllerResultDone, Shared on service: %@", service);
                break;

            default:
                DLog(@"Unhandled result: %d", result);
                break;
        }

        dispatch_async(dispatch_get_main_queue(), ^{
            [parentViewController dismissViewControllerAnimated:YES completion:^{
                DLog(@"Dismissed a controller here!");
            }];
        });
    };

    [controller setCompletionHandler:handler];

    [parentViewController presentViewController:controller animated:YES completion:^{
        DLog(@"Presented %@!", controller);
    }];
}
