Question

I have a tableview with only a few rows. So instead of displaying a bunch of blanks I added a blank UIView to the tableview.footer. However I would like the last cell to cast a dropshadow on the UIView. How would I achieve this? Here is my current code.

- (void)viewDidLoad
{
    [super viewDidLoad];
    UIView *emptyView = [[UIView alloc] initWithFrame:CGRectZero];
    CALayer *layer = [emptyView layer];
    [layer setShadowOffset:CGSizeMake(0, 1)];
    [layer setShadowColor:[[UIColor darkGrayColor] CGColor]];
    [layer setShadowRadius:8.0];
    [layer setShadowOpacity:0.8];
    self.tableView.tableFooterView = emptyView;
}

EDIT:
It is adding the UIView to the footer but not creating the dropshadow. I’m not sure the layer is the best approach for this or even correct for this type of thing.

I ended up using

shadowBackgroundView.layer.shadowOpacity = 0.3; 
shadowBackgroundView.layer.shadowRadius = 2;
shadowBackgroundView.layer.shadowColor = [[UIColor blackColor] CGColor];
shadowBackgroundView.layer.shadowOffset = CGSizeMake(0.0, 1.0);
CGPathRef shadowPath = [UIBezierPath bezierPathWithRoundedRect: shadowBackgroundView.bounds 
                                                         byRoundingCorners: UIRectCornerAllCorners
                                                               cornerRadii: CGSizeMake(PageCellBackgroundRadius, PageCellBackgroundRadius)].CGPath;
shadowBackgroundView.layer.shadowPath = shadowPath;
shadowBackgroundView.layer.shouldRasterize = YES;

[self addSubview: shadowBackgroundView];
