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

       NSString *cellId = @"cell";
       UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId];
       NSInteger lastRowIndexInSection = [tableView numberOfRowsInSection:indexPath.section] - 1;

       if (row == lastRowIndexInSection) {
              CGFloat halfWidthOfCell = cell.frame.size.width / 2;
              cell.separatorInset = UIEdgeInsetsMake(0, halfWidthOfCell, 0, halfWidthOfCell);
       }
}

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
    }
}

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

       NSString *cellId = @"cell";
       UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId];
       NSInteger lastRowIndexInSection = [tableView numberOfRowsInSection:indexPath.section] - 1;

       if (row == lastRowIndexInSection) {
              CGFloat halfWidthOfCell = cell.frame.size.width / 2;
              cell.separatorInset = UIEdgeInsetsMake(0, halfWidthOfCell, 0, halfWidthOfCell);
       }
}

当你定义你的表时，只需添加:

func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
    // Removes separator lines
    tableView.separatorStyle = UITableViewCell.SeparatorStyle.none
    return UIView()
}

神奇的一行是tableView。separatorStyle = UITableViewCell.SeparatorStyle.none

试试下面的代码，也许能帮你解决问题

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

   NSString* reuseIdentifier = @"Contact Cell";

    UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:reuseIdentifier];
    if (nil == cell) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseIdentifier];
if (indexPath.row != 10) {//Specify the cell number
        cell.backgroundView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bgWithLine.png"]];

} else {
        cell.backgroundView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bgWithOutLine.png"]];

}

    }

    return cell;
}
