I made a custom UITableViewCell in IB, but for some reason, despite the single line option for separator being selected, there are no separator lines on my table.
Ha
In my case, i forgot to call [super layoutSubviews] after overriding the layoutSubviews method. Took me two hours to find the problem.
If you programmatically add subviews to your cell, make sure you add the subviews
to cell.contentView and NOT to cell
[cell.contentView addSubview:subview];
