Is it possible to call native ios Facebook login dialog from just a web page (not a web app)?

Question

We have an ios app that uses native Facebook login just fine.

Then we also have a website (app is basically an optimized client for it) where people can login via Facebo

Answer 1

For opening face book app you can use Custom URL scheme. But i am not sure if u can authenticate user from it. In case if you could also then it will be confined up to the fb account which is already configured on that device app .so better try to use face book api or something
