Swift 3 /Swift 4 /Swift 5 +，非常简单

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
      //MARK:- For Hiding the extra lines in table view.
    tableView?.tableFooterView = UIView()
}

OR

override func viewDidLoad(_ animated: Bool) {
    super.viewDidLoad(animated)
      //MARK:- For Hiding the extra lines in table view.
    tableView?.tableFooterView = UIView()
}

迅速:

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.tableFooterView = UIView()
    }

Swift 4.0扩展

只是一个小扩展的故事板:

extension UITableView {
    @IBInspectable
    var hideSeparatorForEmptyCells: Bool {
        set {
            tableFooterView = newValue ? UIView() : nil
        }
        get {
            return tableFooterView == nil
        }
    }
}

如果你要子类化UITableView，你需要这样做…

-(void)didMoveToSuperview {
    [super didMoveToSuperview];
    self.tableFooterView = [UIView new];
}

这里有另一种不使用分组表样式的方法，一种您可能猜不到的方法。向表中添加页眉和页脚(也许一个或另一个就足够了，还没有选中)会导致分隔符从填充行/空白行中消失。

我无意中发现了这一点，因为我想在桌子的顶部和底部留出一点空间，以减少触碰按钮的风险，而不是手指肥大的表格单元格。下面是一个将空白视图作为页眉和页脚插入的方法。使用您喜欢的任何高度，您仍然可以消除额外的分隔线。

- (void) addHeaderAndFooter
{
    UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 10)];
    v.backgroundColor = [UIColor clearColor];
    [self.myTableView setTableHeaderView:v];
    [self.myTableView setTableFooterView:v];
    [v release];
}

In response to @Casebash, I went back to the code in my app ("AcmeLists" List Manager in iTunes store...) and short-circuited the addHeaderAndFooter method to verify. Without it, I have the extra row separators; with the code, I have what you see in this window snap: no table row separators picture. So I'm not sure why it wouldn't have worked for you. Moreover, it makes sense to me that having any custom footer on a table view would necessarily have to stop drawing row separators for blank rows below it. That would be hideous. For reference, I looked at tables where there were more rows than could be viewed on screen, and then for a table with two rows. In both cases, no extraneous separators.

也许您的自定义视图实际上并没有添加。要检查这一点，将背景颜色设置为clearColor以外的颜色，例如，[UIColor redColor]。如果您在表格底部没有看到一些红色条，则表示您的页脚没有设置。

试试这个

针对Objective C

- (void)viewDidLoad 
 {
  [super viewDidLoad];
  // This will remove extra separators from tableview
  self.yourTableView.tableFooterView = [UIView new];
}

为迅速

override func viewDidLoad() {
 super.viewDidLoad()
 self.yourTableView.tableFooterView = UIView()
}
