iOS SMS window always stays active and it is impossible to cancel it on iPhone

Hi all.

I need to register an own URL handler which handles my custom URL scheme as 'smsto'. In this scheme I use the custom URL which allows to transfer a custom pre-defined SMS body.

For this purpose I have created my URL handler ExtendedUrlHandler with following code:

...

void ExtendedUrlHandler::registerSchemes()
{
    QDesktopServices::setUrlHandler(QLatin1String(INSTAGRAM_SCHEME),
                                    this, "handleInstagramUrl");

    QDesktopServices::setUrlHandler(QLatin1String(SMS_SCHEME),
                                    this, "handleSmsUrl");
}

void ExtendedUrlHandler::unregisterSchemes()
{
    QDesktopServices::unsetUrlHandler(QLatin1String(INSTAGRAM_SCHEME));
    QDesktopServices::unsetUrlHandler(QLatin1String(SMS_SCHEME));
}

...

And then following method launch the native iPhone SMS dialer:

void ExtendedUrlHandler::handleSmsUrl(const QUrl &url)
{
    qCWarning(EXTURL_HANDLER) << "Start pase url:" << url;

    QString smsScheme;
    QString smsPhone;
    QString smsBody;
    const auto isParsed = parseSmsUrl(url, &smsScheme, &smsPhone, &smsBody);
    if (!isParsed)
        return;

    UIWindow *window = qt_apple_sharedApplication().keyWindow;

    const auto messageViewController = [[[MFMessageComposeViewController alloc] init] autorelease];
    if ([MFMessageComposeViewController canSendText]) {
        messageViewController.body = smsBody.toNSString();
        messageViewController.recipients = [NSArray arrayWithObjects:smsPhone.toNSString(), nil];
        messageViewController.messageComposeDelegate = nil;
        [window.rootViewController presentViewController:messageViewController animated:YES completion:nil];
    }
}

But a problem that I can't exit from the SMS dialer back to my application UI. It always show the SMS dialer, even I click to 'Cancel' button.

Could someone point me to the right way?

I fixed this now. Need just to use a delegate where rectore the application's UIView, see for example this.
