You can resize the UIBezierpath relative to your UITextview frame size like this:

CGRect box = CGPathGetBoundingBox(bezierpath.CGPath)
CGFloat scaleX = textView.frame.size.width / box.frame.size.width;
CGFloat scaleY = textView.frame.size.height / box.frame.size.height;
CGAffineTransform transform = CGAffineTransformMakeScale(scaleX, scaleY);
CGPathRef intermediatePath = CGPathCreateCopyByTransformingPath(bezierpath.CGPath, &transform);
bezierPath.CGPath = intermediatePath;
CFRelease(intermediatePath);

Hope that help!
