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);
}

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
    }
}

在viewDidLoad中添加这一行:

self.tableView.separatorColor = [UIColor clearColor];

在cellForRowAtIndexPath中:

适用于iOS低版本

if(indexPath.row != self.newCarArray.count-1){
    UIImageView *line = [[UIImageView alloc] initWithFrame:CGRectMake(0, 44, 320, 2)];
    line.backgroundColor = [UIColor redColor];
    [cell addSubview:line];
}

适用于iOS 7以上版本(包括iOS 8)

if (indexPath.row == self.newCarArray.count-1) {
    cell.separatorInset = UIEdgeInsetsMake(0.f, cell.bounds.size.width, 0.f, 0.f);
}

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
        }
    }
}

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

在iOS 10.2中运行良好

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)
        }
