safari navigation bars do not disappear

Question

I’ll explain this through prints

basically, there are these navigation/address safari bars

http://prntscr.com/8mgtda

Now, when scrolling (who uses an iphone, can see, shrinks the navigation bar and the options of the safari disappear, you can see from the example of www.apple.com or maisfutebol).

Now, I’m making a site, where whenever I scroll, do the same behavior, whatever browser it is.

What does not happen.

I’ll show you what I got http://prntscr.com/8mguji I have a footer Fixed, but honestly, I don’t think that’s the problem, because more football also has a similar.

I already changed the meta tag too, and it didn’t solve my problem.

The same I did in javascript using this code below and nothing did either

window.scrollTo(0, 1);

So someone knows the solution to this problem with browsers?
