        float viewWidth = 80;        
        UIBezierPath * path = [UIBezierPath bezierPath];
        path.lineWidth = 2;
        [[UIColor whiteColor] setStroke];
        [path moveToPoint:CGPointMake((sin(M_1_PI / 180 * 60)) * (viewWidth / 2), (viewWidth / 4))];
        [path addLineToPoint:CGPointMake((viewWidth / 2), 0)];
        [path addLineToPoint:CGPointMake(viewWidth - ((sin(M_1_PI / 180 * 60)) * (viewWidth / 2)), (viewWidth / 4))];
        [path addLineToPoint:CGPointMake(viewWidth - ((sin(M_1_PI / 180 * 60)) * (viewWidth / 2)), (viewWidth / 2) + (viewWidth / 4))];
        [path addLineToPoint:CGPointMake((viewWidth / 2), viewWidth)];
        [path addLineToPoint:CGPointMake((sin(M_1_PI / 180 * 60)) * (viewWidth / 2), (viewWidth / 2) + (viewWidth / 4))];
        [path closePath];
        
        CAShapeLayer * shapLayer = [CAShapeLayer layer];
        shapLayer.lineWidth = 2;
        shapLayer.strokeColor = [UIColor whiteColor].CGColor;
        shapLayer.path = path.CGPath;

        _headerImageView.layer.mask = shapLayer;


        同理其他多边形也可以实现。

           圆形的:_headerImageView.layer.cornerRadius = viewWidth / 2;
                       _headerImageView.clipsToBounds = true;
也可以设置线的宽度和颜色。
