Get UIBezierPath Stroke's Outline Path

Question

I have a UIBezierPath stroke, now I want to get the stroke\'s outline path(not the stroke\'s path itself), is there a way I could get that? or at least NS

Answer 1

You can use CGPathCreateCopyByStrokingPath for this.

UIBezierPath *path = ...;
CGFloat lineWidth = 10;
CGPathRef cgStrokedPath = CGPathCreateCopyByStrokingPath(path.CGPath, NULL,
    lineWidth, kCGLineCapRound, kCGLineJoinRound, 0);
UIBezierPath *strokedPath = [UIBezierPath bezierPathWithCGPath:cgStrokedPath];
