UITableView: the proper way to display a separator for the last cell

Question

The question is what\'s the right-most way to display a separator in the last cell in a table/section.

Basically this is what I am after.

Answer 1

In iOS 8, if you have a plain style UITableView, and add a footer, the last separator is gone. However, you can easily recreate it by adding a custom separator view to the footer.

This example exactly mimics Today Widget separator style

    override func tableView(tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {

        //create footer view
        let result = UIView()
        result.frame.size.height = tableView.rowHeight

        //recreate last cell separator, which gets hidden by footer
        let sepFrame = CGRectMake(15, -0.5, tableView.frame.width, 0.5);
        let vibrancyEffectView = UIVisualEffectView.init(effect: UIVibrancyEffect.notificationCenterVibrancyEffect())
        vibrancyEffectView.frame = sepFrame
        vibrancyEffectView.contentView.backgroundColor = tableView.separatorColor
        result.addSubview(vibrancyEffectView)
        return result
}

Answer 2

I used the table view style "grouped" to add this line:

And furthermore it avoids sticking the last separator line to stick on the screen when scrolling out!
