Eu tenho uma subclasse deUIButton onde eu sobrescrevodrawRect para um botão personalizado.

Mas agora a célula não destaca.

Como posso consertar isso?

Eu tenho o código pronto para outro personalizado drawRect para quando a célula é pressionada.

<code>- (void)drawRect:(CGRect)rect

    CGContextSaveGState(context);
    {
        CGFloat xOffset = shadowOffset.width + round(roundedRectangleBorderRect.size.width);
        CGFloat yOffset = shadowOffset.height;
        CGContextSetShadowWithColor(context,
                                    CGSizeMake(xOffset + copysign(0.1, xOffset), yOffset + copysign(0.1, yOffset)),

                                    shadow);

        [roundedRectanglePath addClip];
        CGAffineTransform transform = CGAffineTransformMakeTranslation(-round(roundedRectangleBorderRect.size.width), 0);
        [roundedRectangleNegativePath applyTransform: transform];
        [[UIColor grayColor] setFill];
        [roundedRectangleNegativePath fill];
    }
    CGContextRestoreGState(context);

    CGContextRestoreGState(context);

    [[UIColor blackColor] setStroke];
    roundedRectanglePath.lineWidth = 1;
    [roundedRectanglePath stroke];

    //// Cleanup
    CGGradientRelease(redGradient);
    CGColorSpaceRelease(colorSpace);
}
