我有一个用于绘制钻石的钻石 Thish 代码

int mgX = penThickness * 6; int mgY = penThickness * 2;

    CGPoint st = CGPointMake(MIN(startingPt.x, endingPt.x), MIN(startingPt.y, endingPt.y));
    CGPoint et = CGPointMake(MAX(startingPt.x, endingPt.x), MAX(startingPt.y, endingPt.y));

    CGRect outsideRect = CGRectMake(st.x,st.y, MAX(mgX, et.x-st.x), MAX(mgY, et.y-st.y));
    CGRect insideRect  = CGRectInset(outsideRect, outsideRect.size.width * 0.30f, outsideRect.size.height * 0.30f);

    CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(insideRect), CGRectGetMinY(outsideRect));

    //0 line
    CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(insideRect), CGRectGetMinY(outsideRect));


    //1 line
    CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(outsideRect), CGRectGetMidY(insideRect));

    //2 line
     CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(insideRect), CGRectGetMaxY(outsideRect));


    //3 line
     CGPathAddLineToPoint(pathRef, nil, CGRectGetMinX(insideRect), CGRectGetMaxY(outsideRect));

    //4 line

    CGPathAddLineToPoint(pathRef, nil, CGRectGetMinX(outsideRect), CGRectGetMidY(insideRect));

    CGPathCloseSubpath(pathRef);

我在绘制 Haxagon 的 Hexagone thish 代码中完成了 Draw Complet

int mgX = penThickness * 6; int mgY = penThickness * 6;

CGPoint st = CGPointMake(MIN(startingPt.x, endingPt.x), MIN(startingPt.y, endingPt.y));
CGPoint et = CGPointMake(MAX(startingPt.x, endingPt.x), MAX(startingPt.y, endingPt.y));

CGRect outsideRect = CGRectMake(st.x,st.y, MAX(mgX, et.x-st.x), MAX(mgY, et.y-st.y));
CGRect insideRect  = CGRectInset(outsideRect, outsideRect.size.width * 0.30f, outsideRect.size.height * 0.30f);

CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(insideRect), CGRectGetMinY(outsideRect));

//0 line
CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(insideRect), CGRectGetMinY(outsideRect));


//1 line
CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(outsideRect), CGRectGetMidY(insideRect));

//2 line
 CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(insideRect), CGRectGetMaxY(outsideRect));


//3 line
 CGPathAddLineToPoint(pathRef, nil, CGRectGetMinX(insideRect), CGRectGetMaxY(outsideRect));

//4 line

CGPathAddLineToPoint(pathRef, nil, CGRectGetMinX(outsideRect), CGRectGetMidY(insideRect));

CGPathCloseSubpath(pathRef);
