Round UIButton
<p>I want to know whether drawing a round UIButton(not rounded rect) is possible.</p>

<p>When I add a round image in a UIButton of type custom, then it looks like a round button. But at the moment the button is clicked the boundary of the button becomes visible, so that it looks like a square button, then again when the click ends it looks like a round button.<br />
I want the button to look like a round button even at the moment the click happens. is this possible? </p>
