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;
}

我的要求是将分隔符隐藏在第4和第5单元格之间。我通过

    -(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    if(indexPath.row == 3)
    {
        cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0);
    }
}

  if([_data count] == 0 ){
       [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];//  [self tableView].=YES;
    } else {
      [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];////    [self tableView].hidden=NO;
    }

在willdisplaycell:

cell.separatorInset = UIEdgeInsetsMake(0, cell.bounds.size.width, 0, 0)

在ios7中，UITableView分组样式单元格分隔符看起来有点不同。它看起来有点像这样:

我尝试了凯梅纳兰的回答:

cell.separatorInset = UIEdgeInsetsMake(0, 10000, 0, 0);

然而，这似乎对我不起作用。我不知道为什么。所以我决定使用Hiren的答案，但使用UIView而不是UIImageView，并在iOS 7风格中画出界线:

UIColor iOS7LineColor = [UIColor colorWithRed:0.82f green:0.82f blue:0.82f alpha:1.0f];

//First cell in a section
if (indexPath.row == 0) {

    UIView *line = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 1)];
    line.backgroundColor = iOS7LineColor;
    [cell addSubview:line];
    [cell bringSubviewToFront:line];

} else if (indexPath.row == [self.tableViewCellSubtitles count] - 1) {

    UIView *line = [[UIView alloc] initWithFrame:CGRectMake(21, 0, self.view.frame.size.width, 1)];
    line.backgroundColor = iOS7LineColor;
    [cell addSubview:line];
    [cell bringSubviewToFront:line];

    UIView *lineBottom = [[UIView alloc] initWithFrame:CGRectMake(0, 43, self.view.frame.size.width, 1)];
    lineBottom.backgroundColor = iOS7LineColor;
    [cell addSubview:lineBottom];
    [cell bringSubviewToFront:lineBottom];

} else {

    //Last cell in the table view
    UIView *line = [[UIView alloc] initWithFrame:CGRectMake(21, 0, self.view.frame.size.width, 1)];
    line.backgroundColor = iOS7LineColor;
    [cell addSubview:line];
    [cell bringSubviewToFront:line];
}

如果使用这个，请确保在第二个If语句中插入正确的表视图高度。我希望这对某些人有用。

来跟进Hiren的回答。

在ViewDidLoad和下面一行:

self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;

或者，如果你正在使用XIB或storyboard，将“separator”更改为“none”:

在CellForRowAtIndexPath中添加这个:

CGFloat separatorInset; // Separator x position 
CGFloat separatorHeight; 
CGFloat separatorWidth; 
CGFloat separatorY; 
UIImageView *separator;
UIColor *separatorBGColor;

separatorY      = cell.frame.size.height;
separatorHeight = (1.0 / [UIScreen mainScreen].scale);  // This assures you to have a 1px line height whatever the screen resolution
separatorWidth  = cell.frame.size.width;
separatorInset  = 15.0f;
separatorBGColor  = [UIColor colorWithRed: 204.0/255.0 green: 204.0/255.0 blue: 204.0/255.0 alpha:1.0];

separator = [[UIImageView alloc] initWithFrame:CGRectMake(separatorInset, separatorY, separatorWidth,separatorHeight)];
separator.backgroundColor = separatorBGColor;
[cell addSubView: separator];

这是一个结果的例子，我显示一个动态单元格的tableview(但只有一个内容)。结果是，只有一个有分隔符，而不是所有的“虚拟”tableview自动添加填充屏幕。

编辑:对于那些不经常阅读注释的人来说，实际上有一种更好的方法，只需几行代码:

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