对于iOS7或更高版本，更简洁的方法是使用INFINITY而不是硬编码的值。当屏幕旋转时，您不必担心更新单元格。

if (indexPath.row == <row number>) {
    cell.separatorInset = UIEdgeInsetsMake(0, INFINITY, 0, 0);
}

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);
}

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)
        }

实现这一点的最好方法是关闭默认的行分隔符，子类UITableViewCell，并添加一个自定义的行分隔符作为contentView的子视图-参见下面的自定义单元格，用于表示一个SNStock类型的对象，它有两个字符串属性，ticker和name:

import UIKit

private let kSNStockCellCellHeight: CGFloat = 65.0
private let kSNStockCellCellLineSeparatorHorizontalPaddingRatio: CGFloat = 0.03
private let kSNStockCellCellLineSeparatorBackgroundColorAlpha: CGFloat = 0.3
private let kSNStockCellCellLineSeparatorHeight: CGFloat = 1

class SNStockCell: UITableViewCell {

  private let primaryTextColor: UIColor
  private let secondaryTextColor: UIColor

  private let customLineSeparatorView: UIView

  var showsCustomLineSeparator: Bool {
    get {
      return !customLineSeparatorView.hidden
    }
    set(showsCustomLineSeparator) {
      customLineSeparatorView.hidden = !showsCustomLineSeparator
    }
  }

  var customLineSeparatorColor: UIColor? {
   get {
     return customLineSeparatorView.backgroundColor
   }
   set(customLineSeparatorColor) {
     customLineSeparatorView.backgroundColor = customLineSeparatorColor?.colorWithAlphaComponent(kSNStockCellCellLineSeparatorBackgroundColorAlpha)
    }
  }

  required init(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
  }

  init(reuseIdentifier: String, primaryTextColor: UIColor, secondaryTextColor: UIColor) {
    self.primaryTextColor = primaryTextColor
    self.secondaryTextColor = secondaryTextColor
    self.customLineSeparatorView = UIView(frame:CGRectZero)
    super.init(style: UITableViewCellStyle.Subtitle, reuseIdentifier:reuseIdentifier)
    selectionStyle = UITableViewCellSelectionStyle.None
    backgroundColor = UIColor.clearColor()

    contentView.addSubview(customLineSeparatorView)
    customLineSeparatorView.hidden = true
  }

  override func prepareForReuse() {
    super.prepareForReuse()
    self.showsCustomLineSeparator = false
  }

  // MARK: Layout

  override func layoutSubviews() {
    super.layoutSubviews()
    layoutCustomLineSeparator()
  }

  private func layoutCustomLineSeparator() {
    let horizontalPadding: CGFloat = bounds.width * kSNStockCellCellLineSeparatorHorizontalPaddingRatio
    let lineSeparatorWidth: CGFloat = bounds.width - horizontalPadding * 2;
    customLineSeparatorView.frame = CGRectMake(horizontalPadding,
      kSNStockCellCellHeight - kSNStockCellCellLineSeparatorHeight,
      lineSeparatorWidth,
      kSNStockCellCellLineSeparatorHeight)
  }

  // MARK: Public Class API

  class func cellHeight() -> CGFloat {
    return kSNStockCellCellHeight
  }

  // MARK: Public API

  func configureWithStock(stock: SNStock) {
    textLabel!.text = stock.ticker as String
    textLabel!.textColor = primaryTextColor
    detailTextLabel!.text = stock.name as String
    detailTextLabel!.textColor = secondaryTextColor
    setNeedsLayout()
  } 
}

要禁用默认的行分隔符，请使用tableView。separatorStyle = UITableViewCellSeparatorStyle.None;消费者方面相对简单，见下面的例子:

private func stockCell(tableView: UITableView, indexPath:NSIndexPath) -> UITableViewCell {
  var cell : SNStockCell? = tableView.dequeueReusableCellWithIdentifier(stockCellReuseIdentifier) as? SNStockCell
  if (cell == nil) {
    cell = SNStockCell(reuseIdentifier:stockCellReuseIdentifier, primaryTextColor:primaryTextColor, secondaryTextColor:secondaryTextColor)
  }
  cell!.configureWithStock(stockAtIndexPath(indexPath))
  cell!.showsCustomLineSeparator = true
  cell!.customLineSeparatorColor = tintColor
  return cell!
}

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
}

当我使用扩展和调用layoutSubviews()立即更新布局视图时，它为我工作。

extension UITableViewCell {

    func removeSeparator() {
        separatorInset = UIEdgeInsetsMake(0, bounds.size.width, 0, 0)
    }
}

override func layoutSubviews() {
    super.layoutSubviews()

    removeSeparator()
}
