Prevent UIButton from not auto resize
<p>I have an application containing a iPad view with a set of UIButtons each containing a image that I position properly on the UI. When my application run it resize the images all wrong and not keep the width as I did it in Interface Builder.</p>

<p>Basically: I got a picture of a vehicle (a big UIImageView) and on that picture I put a UIButton that is an image of a part of the vehicle since when you choose a part it need to change to a different image. So the UIButton is position properly with layout to fit in the area on the picture. But when I run on device it auto-resize the UIButton that I don't want it to do.</p>
