As others said, usually there's two ways to do this, either create a CALayer or a UIView separator of 1px and add it to contentView.

Over time I've seen multiple projects do this differently, and sometimes, even multiple different ways in the same project. It's also easy to introduce bugs because of cell reuse and also, for proper rendering of pixel lines, one must incorporate the screen scale: (1.0 / [UIScreen mainScreen].scale).

I've created a library that simplifies this to just a single method class, with no subclassing required. https://github.com/kgaidis/KGViewSeparators

Objective-C:

[view kg_show:YES separator:KGViewSeparatorTop color:[UIColor blackColor] lineWidth:KGViewSeparatorLineWidth(1.0) insets:UIEdgeInsetsMake(0, 15.0, 0, 15.0)];

Swift:

view.kg_show(true, separator: .Bottom, color: UIColor.blackColor(), lineWidth: KGViewSeparatorLineWidth(1.0), insets: UIEdgeInsetsZero)
