body: <p>I am using CGrect to draw circle with border but i didn't get sharp border of circle here is my code:</p>
  
  <pre><code> CGRect rect = CGRectMake(lastPoint1.x - CircleRadius ,lastPoint1.y - CircleRadius,CircleDia,CircleDia);
      CGContextSetFillColorWithColor(ctx, [Util_color getThemeColor].CGColor);
      CGContextFillEllipseInRect(ctx, rect);
      CGContextSetRGBStrokeColor(ctx, 255.0, 255.0, 255.0, 1.0);
      CGContextStrokeEllipseInRect(ctx, rect);
      CGContextSetLineCap(UIGraphicsGetCurrentContext(), kCGLineCapRound);
      CGContextSetLineWidth(ctx, 3.0);
       CGContextSetShouldAntialias(ctx, YES);
      CGContextSetLineCap(cox,kCGLineCapRound);
  </code></pre>
