Ok, but are You suggesting that when I change ui_controls from 0 to 1, button should be visible also on iOS? Because I changed this and now my iframe in inspector looks like:
<iframe src="https://sketchfab.com/models/e27289dc4cf247119a5a6798f4f2f812/embed?api_version=1.0.0&api_id=547777971942182&internal=0&ui_infos=0&ui_controls=1&watermark=1&continuous_render=0&supersample=0&camera=0" id="api-frame" allowfullscreen="" mozallowfullscreen="true" webkitallowfullscreen="true"></iframe>
but stil button isn't visible on iOS.
So i want to know if i can see this button on iOS and now i'm still doing something wrong (ie i should test it not on codepen) or is it impossible to get at all on iOS? Thanks!
