问题:

Old trick with window.scrollTo(0,1); doesn't work. And even worse, the address bar moves only a bit and gets stuck halfway out sometimes.

回答1:

It is a combination of many things as I have found when researching this issue for myself. Here's the code that properly works on iOS5: (I know I'm a little late, but an answer is an answer, hopefully it can help people in the future)

<!DOCTYPE html>
<html>
<head>
<title>Hide Address Bar</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<script>
 window.addEventListener("load",function() {
   setTimeout(function(){
    window.scrollTo(0, 0);
    }, 0);
 });
</script>
<style>
 body { min-height: 480px; }
</style>
</head>
<body>
 <h1>Content</h1>
</body>
</html>

i guess the code should still work..

anyways here is the correct way to tell mobile safari that you want the full screen: click me

e.g. use

<meta name="apple-mobile-web-app-capable" content="yes" />

EDIT

Apple uses a new mobile-ui property to display a minimal UI in safari:

A property, minimal-ui, has been added for the viewport meta tag key that allows minimizing the top and bottom bars on the iPhone as the page loads. While on a page using minimal-ui, tapping the top bar brings the bars back. Tapping back in the content dismisses them again.

use it like this:

<meta name="viewport" content="width=device-width, initial-scale=1, minimum-scale=1.0, maximum-scale=1.0, minimal-ui" />

Since IOS7 the window.scrollTo trick doesn't work anymore. There is no work around for the moment except to invite the user to add your website to Home Screen.

Is it possible to hide the address bar in iOS 7 Safari?

Impossible to hide navigation bars in Safari iOS 7 for iPhone/iPod touch

On iOS 7 you can use the minimal-ui meta tag. Unfortunately, that was removed in iOS 8.

For iOS 8 there's a project called brim that is supposed to bring back the minimal-ui type functionality. It can be found here: https://github.com/gajus/brim
