Sphinx on iOS

I made the server and client parts. I used BaseUrl with https://. I did it from the description of your help "Quickstart". Everything worked fine for Windows, Mac OS. But when creating an application for iOS, when I click on the authorization button (as in the example) - nothing happens at all. It does not redirect to the browser. What am I doing wrong? Do I need to add something for the client on iOS?

Can you be more specific at what URL doesn't work? Which "authorization button" are you referring to, exactly?

You can't open the login form, or after the login is processed, you are not redirected to the original app?
