Gentlemen,
For iOS works general cross-platform Qt url handling mechanism.
//
// Register for: iOS "Open In" file sharing and for our special file extensions
//
QDesktopServices::setUrlHandler("file", this,
"handle_shared_ios_file_and_app_ext_we_are_registed_for");
Existing Qt iOS delegate calls all URL-handling.
Take care.
Regards,
Robert
