Can background or borders be removed from UISearchBar?

Question

I'd like to get something like this:

But I was not able to remove original background (I'm using iOS5). However, it seems Apple did it:

How can I create what I want? Or, there is no choice and the only alternative I have is customize a UITextField?

Thanks for suggestions and ideas!

EDIT: After first reply, this is what I got:

Does anyone how can I remove white inner background without making all component semitransparent changing its alpha value? BTW, can I change white color by black color?

Answer 1

Try this code,It worked for me

for (id img in yourSearchBar.subviews) {
        if ([img isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
           [img removeFromSuperview];    
        }
    }

In the above code yourSearchBar is the searchbar from which you want to remove the background, And the for loop is searching for the background image of UISearchBar
