title: iOS- Draw Circle with Center and radius
body: <p>I want to draw a circle by using just center (x,y) and radius r.</p>
  
  <p>I drew some circles by using <code>CGRect</code>. It works fine when I draw independent circle. But I am trying to draw circles on circumference of a circle.</p>
  
  <p>In this approach Problem is:  The main circle is not moving exactly center of the outside circles, as outside circles are made using <code>CGRect/frame</code>.</p>
  
  <p>So Please help me if we could just draw a circle using center and radius.</p>
