使用Swift 3并采用最快的黑客方法，您可以使用扩展来改进代码:

extension UITableViewCell {

    var isSeparatorHidden: Bool {
        get {
            return self.separatorInset.right != 0
        }
        set {
            if newValue {
                self.separatorInset = UIEdgeInsetsMake(0, self.bounds.size.width, 0, 0)
            } else {
                self.separatorInset = UIEdgeInsetsMake(0, 0, 0, 0)
            }
        }
    }

}

然后，当你配置单元格时:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "identifier", for: indexPath)
    switch indexPath.row {
       case 3:
          cell.isSeparatorHidden = true
       default:
          cell.isSeparatorHidden = false
    }
    return cell
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let cell = tableView.cellForRow(at: indexPath)
    if cell.isSeparatorHidden { 
       // do stuff
    }
}

我的开发环境是

Xcode 7.0 7A220 Swift 2.0 iOS 9.0

以上答案并不完全适用于我

经过尝试，我最终的工作解决方案是:

let indent_large_enought_to_hidden:CGFloat = 10000
cell.separatorInset = UIEdgeInsetsMake(0, indent_large_enought_to_hidden, 0, 0) // indent large engough for separator(including cell' content) to hidden separator
cell.indentationWidth = indent_large_enought_to_hidden * -1 // adjust the cell's content to show normally
cell.indentationLevel = 1 // must add this, otherwise default is 0, now actual indentation = indentationWidth * indentationLevel = 10000 * 1 = -10000

结果是:

iphone的宽度是320。因此，在单元格属性中为separatorInset设置左右值，大于320的一半。

在UITableViewDataSource的cellForRowAtIndexPath方法中

迅速:

if indexPath.row == {your row number} {
    cell.separatorInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: .greatestFiniteMagnitude)
}

or :

cell.separatorInset = UIEdgeInsetsMake(0, 0, 0, UIScreen.main.bounds.width)

对于默认保证金:

cell.separatorInset = UIEdgeInsetsMake(0, tCell.layoutMargins.left, 0, 0)

显示端到端的分隔符

cell.separatorInset = .zero

objective - c:

if (indexPath.row == {your row number}) {
    cell.separatorInset = UIEdgeInsetsMake(0.0f, 0.0f, 0.0f, CGFLOAT_MAX);
}

如果你不想自己画分隔符，使用这个:

  // Hide the cell separator by moving it to the far right
  cell.separatorInset = UIEdgeInsetsMake(0, 10000, 0, 0);

这个API只能从ios7开始使用。

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)
        }
