How to use getControlPointAtIndex function to rotate a UILabel in semicircle in iPhone
<p>I want to rotate a UILabel in semicircle.</p>

<p>So what I am planning to do is use some timing function like CaMediaTimingFunction.</p>

<p>I want to use getControlPointAtIndex method of CaMediaTiming Function so that I can get a set of points to rotate the UILabel. The points which I will get will help me in forming the frame for UILabel.</p>

<p>Does anybody have good idea other than this.</p>

<p>I want to rotate the Label in a semicircle very smoothly.</p>
