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;
}

在iOS9上，我有一个问题，改变分隔符插入也会影响文本和细节标签的定位。

我用这个解出来了

override func layoutSubviews() {
    super.layoutSubviews()

    separatorInset = UIEdgeInsets(top: 0, left: layoutMargins.left, bottom: 0, right: width - layoutMargins.left)
}

如果你不想自己画分隔符，使用这个:

  // Hide the cell separator by moving it to the far right
  cell.separatorInset = UIEdgeInsetsMake(0, 10000, 0, 0);

这个API只能从ios7开始使用。

iphone的宽度是320。因此，在单元格属性中为separatorInset设置左右值，大于320的一半。

你必须采取自定义单元格，并添加标签和设置约束，如标签应覆盖整个单元格区域。 并在构造函数中编写下面的行。

- (void)awakeFromNib {
    // Initialization code
    self.separatorInset = UIEdgeInsetsMake(0, 10000, 0, 0);
    //self.layoutMargins = UIEdgeInsetsZero;
    [self setBackgroundColor:[UIColor clearColor]];
    [self setSelectionStyle:UITableViewCellSelectionStyleNone];
}

也设置UITableView布局边距如下

tblSignup.layoutMargins = UIEdgeInsetsZero;

我的开发环境是

Xcode 7.0 7A220 Swift 2.0 iOS 9.0

以上答案并不完全适用于我

经过尝试，我最终的工作解决方案是:

let indent_large_enought_to_hidden:CGFloat = 10000
cell.separatorInset = UIEdgeInsetsMake(0, indent_large_enought_to_hidden, 0, 0) // indent large engough for separator(including cell' content) to hidden separator
cell.indentationWidth = indent_large_enought_to_hidden * -1 // adjust the cell's content to show normally
cell.indentationLevel = 1 // must add this, otherwise default is 0, now actual indentation = indentationWidth * indentationLevel = 10000 * 1 = -10000

结果是:
