iOS 7 input elements moving fixed positioned elements

I'm trying to recompile an app for iOS 7, since nothing of the old one works so far. One of the many problems is that I'm using some inputs inside UIWebViews. Text inputs, pickers etc.

Now, when the iOS 7 shining white keyboard appears, all the bottom fixed elements in the webpage (such as, confirm buttons) are scrolled upward, as if the 'top' of the virtual keyboard is the new bottom of my UIWebView. This is a substantially different behavior from iOS6.x

Is there any magic trick to make the virtual keyboard behavior work like it used to, without injecting JS/CSS to the webView?


This fixed the problem for my cordova app. I'm not sure if it applies to you but just in case.

Check your html meta tags for something like this:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0">

Replace it with this:

<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0, maximum-scale=1.0, target-densityDpi=device-dpi" />

In our case this would fix itself as soon as user scrolls. So this is the fix we've been using to simulate a scroll on blur on any input or textarea:

$(document).on('blur', 'input, textarea', function () {
    setTimeout(function () {
        window.scrollTo(document.body.scrollLeft, document.body.scrollTop);
    }, 0);

I ran across exactly the same problem & gave up after two days of experimenting. It seems that: a) all bottom-fixed elements go upwards so that their bottom offset is relative to the top edge of the keyboard c) all top-fixed elements stay in their original position (do not move upwards as they used to) - note that top-absolute elements work ok.

The only solution I found was to have a custom iPad stylesheet that replaces all fixed elements with absolute elements, sets the css bottom property to auto and uses top instead

Opposum, your solution worked for me but only when the scale was set to 1.0. If I set it to 0.9 then it would be like it was before your suggested fix. I set initial-scale, maximum-scale, and minimum-scale to 0.9 and the bouncing effect of the fixed objects when the keyboard appeared was still happening.
