How to draw a rounded rectangle in Core Graphics / Quartz 2D?

Question

I need to draw an outline for a rounded rectangle. I know I can make lines and arcs, but maybe there is also a function for rounded rects?

Answer 1

CGPathCreateWithRoundedRect() will do what you want.

CGPathRef CGPathCreateWithRoundedRect(
   CGRect rect,
   CGFloat cornerWidth,
   CGFloat cornerHeight,
   const CGAffineTransform *transform
);
