Hello! I've a custom shape drawing using coregraphics and i want to add a drop shadow and a gradient to it also. I've been trying and searching a lot of informations on how to combine and do this, but i can't get it to work. I'm able to draw only one either. Anyone doing this already or know how to do this? Thank you.

Quartz only applies shadows to fills and strokes. Drawing a gradient does not count as a fill.
Fill with a solid color (to draw the shadow), then draw the gradient in the same area.

so just to clarify...1. draw a shape with solid color fill2. save the state3. draw the shadow4. restore the state5. draw the same shape as point 1 but with the gradientis this correct? so i need to draw the shape 3 times right?

There is no way to “draw the shadow”. Quartz draws the shadow for you when you fill or stroke. So, set the shadow, then fill (with a solid color) the shape, then draw the gradient over it.

Looks like you're right Peter, but I think it might be an oversight, albeit a difficult one to fix. Images and text draw shadows, for example, as do transparency layers and CGLayers. I cannot think of any non-shading based drawing that _doesn't_ produce a shadow. The header just says "After a shadow is specified, all objects drawn subsequently will be shadowed."
