UIView shadow not working

Question

This is my code.

listView.layer.masksToBounds = NO; listView.layer.shadowOffset = CGSizeMake(-3, 3); listView.layer.shadowColor=[[UIColor blackColor] CGColor]; listView.layer.shadowRadius = 4; listView.layer.shadowOpacity = 1.0; [listView.layer setShouldRasterize:YES]; 

It works good with shadow effect.

While changing

listView.layer.masksToBounds = YES; 

I didnt get shadow effect.

Answer 1

The shadow is actually drawn below the UIView. If you set maskToBounds to YES, this clips any drawing outside of the UIView frame. Here is a SO link that describes this in more detail.

Answer 2

The shadow is drawn outside of the layer's bounds. You have to set listView.layer.masksToBounds = NO to see the shadow

if you set listView.layer.masksToBounds = YES you can't draw anything out side of bounds so you can not get shadow
