title: How to draw a custom UIView that is just a circle - iPhone app
body: <p>How would I go about drawing a custom UIView that is literally just a ball (a 2D circle)? Would I just override the drawRect method? And can someone show me the code for drawing a blue circle? </p>
  
  <p>Also, would it be okay to change the frame of that view within the class itself? Or do I need to change the frame from a different class?</p>
  
  <p>(just trying to set up a ball bouncing around)</p>
