Custom Bottom Border not appearing on iPad

Question

I added a bottom border to a uitableviewcell programmatically (iPhone - Create custom UITableViewCell top and bottom borders):

UIView *bottomLineView = [[UIView alloc] initWithFrame:CGRectMake(0, cell.bounds.size.height, self.view.bounds.size.width, 1)];
bottomLineView.backgroundColor = [UIColor grayColor];
[cell.contentView addSubview:bottomLineView];

It's not displaying on an ipad unless you highlight it. All the other cells below and above it have the background color set to clear.. It displays fine on the iPhone

Answer 1

Move the line one pixel up. Right now it's outside of the frame, getting overlayed by the next cell.

UIView *bottomLineView = [[UIView alloc] initWithFrame:CGRectMake(0,
                               cell.bounds.size.height - 1, 
                               self.view.bounds.size.width, 
                               1)];
