Transparent UIToolBar over UIWebView

Question

I want to have a transparent UIToolBar over a UIWebView, so that the user gets a wider perspective and overview.

However, when I do this, you cannot see the bottom of the page. I thought about setting an offset at the bottom, but that can't be trusted, as the level of zoom may vary (and each pixel will be worth less).

How can I make the webView scroll and stop at the top edge of the UIToolBar?

Answer 1

I tried out Emils solution, but it doesn't work for iOS7 since it there inherits from an UIWebViewScrollView. So, adapted his code to the following:

for (id view in [self.webView subviews]){
    if ([view respondsToSelector:@selector(setContentInset:)]){
        [(UIScrollView *)view setContentInset:UIEdgeInsetsMake(0, 0, 44, 0)];
    }
}
