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);
}

我能找到的唯一解决办法就是下一个

extension UITableViewCell {
    func separator(hide: Bool) {
        separatorInset.left = hide ? self.bounds.width * 1.5 : 16 // or whatever you want to be the left inset
    }
}

我不知道为什么，但是self.bounds.width没有像预期的那样工作，所以我乘以1.5。

如果你想隐藏一个单元格，你只需要这样做:

cell.separator(hide: true)

对于其余的单元格，只发送参数为false

cell.separator(hide: false)

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
    }
}

所有答案的代码将使单元格填充为零，而不是默认值。我在iOS 11 iPad Pro 12中看到了这个问题。”

但我有一个解决方案(“肮脏的hack”)，那就是使一个空的部分，将使分隔线隐藏。

下面是我使用的代码:

typedef enum PXSettingsTableSections {
    PXSettingSectionInvite = 0,
    PXSettingSectionAccount,
    PXSettingSectionPrivacy,
    PXSettingSectionCreation,
    PXSettingSectionTest,
    PXSettingSectionAboutHide,  // invisble section just to hide separator Line
    PXSettingSectionFooterHide, // invisble section just to hide separator Line
    PXSettingSectionNumItems,
} PXSettingsTableSectionsType;


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return PXSettingSectionNumItems;
}


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    switch (section) {
        case PXSettingSectionInvite: return 1;
        case PXSettingSectionAccount:return (isSocialLogin) ? 1 : 2;
        case PXSettingSectionPrivacy: return 1;
        case PXSettingSectionCreation: return 2;
        case PXSettingSectionTest: return 3;
        case PXSettingSectionAboutHide: return 3;
        default: return 0;
    }
}


- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    switch(section)
    {
        case PXSettingSectionInvite: return nil;
        case PXSettingSectionAccount: return @"Account";
        case PXSettingSectionPrivacy: return @"Privacy";
        case PXSettingSectionCreation: return @"Someting";
        case PXSettingSectionTest: return @"Test";
        case PXSettingSectionAboutHide: return @" ";
        case PXSettingSectionFooterHide: return @" ";
    }
    return nil;
}


- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {

    UITableViewHeaderFooterView *header = (UITableViewHeaderFooterView *)view;
    if (section == PXSettingSectionFooterHide || section == PXSettingSectionAboutHide) {
        // [UIColor clearColor] will not work 
        [header.contentView setBackgroundColor:[UIColor whiteColor]];
    }
}


- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    // You can control here the size of one specific section
    if(section == PXSettingSectionAboutHide){
        return 0.0000001; //make it real small
    }
    return 45.0;
}


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

    switch(indexPath.section)
    {
        case PXSettingSectionInvite:
            return self.inviteCell;
        case PXSettingSectionAccount:
            if (isSocialLogin) {
                return self.myWalletCell;
            }
            switch(indexPath.row)
            {
                case 0: return self.changePasswordCell;
                case 1: return self.myWalletCell;
            }
        case PXSettingSectionPrivacy:
            switch(indexPath.row)
        {
            case 0: return self.privateAccountCell;
        }
        case PXSettingSectionCreation:
            switch(indexPath.row)
        {
            case 0: return self.videoResolutionCell;
            case 1: return self.selfieMirrorCell;
        }
        case PXSettingSectionTest:
            switch(indexPath.row)
        {
            case 0: return self.termsOfUseImageCell;
            case 1: return self.attributionCell;
            case 2: return self.aboutCell;
        }
        case PXSettingSectionAboutHide:{
            switch(indexPath.row)
            {
                case 0: return self.clearCacheCell;
                case 1: return self.feedbackCell;
                case 2: return self.logoutCell;
            }
        }
    }

    return self.emptyCell;
}

我不相信这种方法在任何情况下都适用于动态单元格……

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

不管你在哪个tableview方法中为动态单元格做这件事，你改变了inset属性的单元格总是有inset属性设置，现在每次它被退出队列时，都会导致缺少行分隔符的狂暴…除非你自己改变。

这样的方法对我很有效:

if indexPath.row == franchises.count - 1 {
  cell.separatorInset = UIEdgeInsetsMake(0, cell.contentView.bounds.width, 0, 0)
} else {
  cell.separatorInset = UIEdgeInsetsMake(0, 0, cell.contentView.bounds.width, 0)
}

这样你就可以在每次加载时更新数据结构状态

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