UISearchbar unable to remove text border
<p>I set a transparent image to a UISearchBar in order to show the background of the view behind it. For some reason it caused a strange truncated blue border to appear on the text field.</p>

<p>Here is how it looks:

<p>Any idea from where did it come from? Any way of removing it?</p>
