我有 CGMutablePathRef 正在制作的路径
CGMutablePathRef pointsPathpath = CGPathCreateMutable();
CGPathMoveToPoint(pointsPathpath, NULL, firstPoint.x, firstPoint.y);
CGPathAddLineToPoint(pointsPathpath, NULL, secondPoint.x, secondPoint.y);
CGPathAddLineToPoint(pointsPathpath, NULL, thirdPoint.x, thirdPoint.y);
CGPathAddLineToPoint(pointsPathpath, NULL, fourthPoint.x, fourthPoint.y);
CGPathCloseSubpath(pointsPathpath);
有没有办法得到它的边界点?
提前致谢。
