Here's my correction: void DPContextAddRoundRect(CGContextRef context, CGRect rect, CGFloat cornerRad) { // Top Left CGContextMoveToPoint(context, rect.origin.x, cornerRad+rect.origin.y); CGContextAddArcToPoint(context, rect.origin.x, rect.origin.y, rect.origin.x + cornerRad, rect.origin.y, cornerRad); // Top right CGContextAddArcToPoint(context, rect.origin.x + rect.size.width, rect.origin.y, rect.origin.x + rect.size.width, rect.origin.y + cornerRad, cornerRad); It seems like you forgot to update the posted code after fixing the bug you mentioned. Here’s my correction:
void DPContextAddRoundRect(CGContextRef context, CGRect rect, CGFloat cornerRad) {
// Top Left
CGContextMoveToPoint(context, rect.origin.x, cornerRad+rect.origin.y);
CGContextAddArcToPoint(context,
rect.origin.x,
rect.origin.y,
rect.origin.x + cornerRad,
rect.origin.y,
cornerRad);
// Top right
CGContextAddArcToPoint(context,
rect.origin.x + rect.size.width,
rect.origin.y,
rect.origin.x + rect.size.width,
rect.origin.y + cornerRad,
cornerRad);

I'm a quartz drawing noob and the thing that I had to figure out on my own was that I needed to bracket the call to your function like so: CGContextBeginPath(context); DPContextAddRoundRect(context, rect, radius); CGContextDrawPath(context, kCGPathStroke); Thanks for the hint! I’m a quartz drawing noob and the thing that I had to figure out on my own was that I needed to bracket the call to your function like so:
