在tableview单元格类中。放这行代码

separatorInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: self.bounds.size.width)

在使用iOS 8.4的Swift中:

/*
    Tells the delegate that the table view is about to draw a cell for a particular row. (optional)
*/
override func tableView(tableView: UITableView,
                        willDisplayCell cell: UITableViewCell,
                        forRowAtIndexPath indexPath: NSIndexPath)
{
    if indexPath.row == 3 {
        // Hiding separator line for only one specific UITableViewCell
        cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0)
    }
}

Note: this snippet above will work on UITableView using dynamic cells. The only problem that you can encounter is when you use static cells with categories, a separator type different than none and a grouped style for the table view. In fact, in this particular case it will not hide the last cell of each category. For overcoming that, the solution that I found was to set the cell separator (through IB) to none and then creating and adding manually (through code) your line view to each cell. For an example, please check the snippet below:

/*
Tells the delegate that the table view is about to draw a cell for a particular row. (optional)
*/
override func tableView(tableView: UITableView,
    willDisplayCell cell: UITableViewCell,
    forRowAtIndexPath indexPath: NSIndexPath)
{
    // Row 2 at Section 2
    if indexPath.row == 1 && indexPath.section == 1 {
        // Hiding separator line for one specific UITableViewCell
        cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0)

        // Here we add a line at the bottom of the cell (e.g. here at the second row of the second section).
        let additionalSeparatorThickness = CGFloat(1)
        let additionalSeparator = UIView(frame: CGRectMake(0,
            cell.frame.size.height - additionalSeparatorThickness,
            cell.frame.size.width,
            additionalSeparatorThickness))
        additionalSeparator.backgroundColor = UIColor.redColor()
        cell.addSubview(additionalSeparator)
    }
}

在你的UITableViewCell子类中，覆盖layoutSubviews并隐藏_UITableViewCellSeparatorView。适用于iOS 10。

override func layoutSubviews() {
    super.layoutSubviews()

    subviews.forEach { (view) in
        if view.dynamicType.description() == "_UITableViewCellSeparatorView" {
            view.hidden = true
        }
    }
}

对于那些专门寻找隐藏分隔线的尤里卡行，这是唯一的解决方案，为我工作:

     row.cellUpdate { (cell, row) in
            cell.separatorInset =  UIEdgeInsets(top: 0, left: 0, bottom: 0, right: CGFloat.greatestFiniteMagnitude)
        }

cell.separatorInset = UIEdgeInsetsMake(0.0, cell.bounds.size.width, 0.0, -cell.bounds.size.width)

在iOS 10.2中运行良好

迅速:

public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    ...

    // remove separator for last cell
    cell.separatorInset = indexPath.row < numberOfRowsInSection-1
        ? tableView.separatorInset
        : UIEdgeInsets(top: 0, left: tableView.bounds.size.width, bottom: 0, right: 0)

    return cell
}

objective - c:

- (UITableViewCell *)tableView:(UITableView *)tableView
     cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    ...

    // remove separator for last cell
    cell.separatorInset = (indexPath.row < numberOfRowsInSection-1)
        ? tableView.separatorInset
        : UIEdgeInsetsMake(0.f, tableView.bounds.size.width, 0.f, 0.f);

    return cell;
}
