How to add a drop shadow to a UIButton?

I would like to add a drop shadow to a UIButton. I tried to use self.layer.shadow* properties. Those properties work in UIView, but they behave differently in UIButton. I would really appreciate it if I could get any pointers to draw the drop shadow. Thank you!

self.layer.cornerRadius = 8.0f;
self.layer.masksToBounds = YES;
self.layer.borderWidth = 1.0f;

self.layer.shadowColor = [UIColor greenColor].CGColor;
self.layer.shadowOpacity = 0.8;
self.layer.shadowRadius = 12;
self.layer.shadowOffset = CGSizeMake(12.0f, 12.0f);

You can subclass UIButton and overwrite the drawRect: method and add manually a drop shadow. That's much more work and you should now a few things about quartz 2d, but the result is exactly what you want. Otherwise you could just add an image, but I prefere to subclass UIButton, because it is very flexible regarding the size of the button, it's more general.
