I have an image of what is happening:
How do I get rid of that drop-shadow?
Try this in cellForRowAtIndexPath, Its works like Charm !!!!
cell.layer.shadowOffset = CGSizeMake(0, 0);
cell.layer.shadowColor = [[UIColor clearColor] CGColor];
cell.layer.shadowRadius = 0;
cell.layer.shadowOpacity = 0.0f;
