我的形状围绕着这条线:

问题是,它显然从1px厚到2px.这是我正在使用的代码:

CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextClearRect(context, rect);

    CGContextSetFillColorWithColor(context, [BUTTON_COLOR CGColor]);
    CGContextSetStrokeColorWithColor(context, [[UIColor blackColor] CGColor]);
    CGContextSetLineWidth(context, 1);

    int radius = 8;


    CGContextMoveToPoint(context, 0, self.frame.size.height / 2);

    CGContextAddLineToPoint(context, POINT_WIDTH, self.frame.size.height);

    CGContextAddLineToPoint(context, rect.origin.x + rect.size.width - radius, 
                            rect.origin.y + rect.size.height);

    CGContextAddArc(context, rect.origin.x + rect.size.width - radius, 
                    rect.origin.y + rect.size.height - radius, radius, M_PI / 2, 0.0f, 1);

    CGContextAddLineToPoint(context, rect.origin.x + rect.size.width, rect.origin.y + radius);

    CGContextAddArc(context, rect.origin.x + rect.size.width - radius, rect.origin.y + radius, 
                    radius, 0.0f, -M_PI / 2, 1);

    CGContextAddLineToPoint(context, POINT_WIDTH, 0); …
