@samvermette的解决方案的变体:

/// Allows for disabling scrolling headers in plain-styled tableviews
extension UITableView {

    static let shouldScrollSectionHeadersDummyViewHeight = CGFloat(40)

    var shouldScrollSectionHeaders: Bool {
        set {
            if newValue {
                tableHeaderView = UIView(frame: CGRect(x: 0, y: 0, width: bounds.size.width, height: UITableView.shouldScrollSectionHeadersDummyViewHeight))
                contentInset = UIEdgeInsets(top: -UITableView.shouldScrollSectionHeadersDummyViewHeight, left: 0, bottom: 0, right: 0)
            } else {
                tableHeaderView = nil
                contentInset = .zero
            }
        }

        get {
            return tableHeaderView != nil && contentInset.top == UITableView.shouldScrollSectionHeadersDummyViewHeight
        }
    }

}

我有另一个更简单的解决方案，使用没有自动布局和一切通过XIB完成:

1/把你的头放在tableview中，直接拖放到tableview上。

2/在新建头部的尺寸检查器中，改变它的自动大小:你应该只保留顶部，左右锚，加上水平填充。

这应该能奏效!

另一种方法是在你想要放置标题的区域之前创建一个空区域，然后把你的标题放在这个区域上。因为部分是空的，所以标题会立即滚动。

let tableView = UITableView(frame: .zero, style: .grouped)

PLUSE

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    if section == 0 {
        return 40
    }else{
        tableView.sectionHeaderHeight = 0
    }

    return 0
}

这有助于使用标题空间

好吧，我知道很晚了，但我必须这么做。 到目前为止，我已经花了10个小时寻找一个可行的解决方案，但没有找到一个完整的答案。我发现了一些提示，但初学者很难理解。因此，我不得不投入我的2美分，完成答案。

正如在少数的答案中所建议的，我能够实现的唯一工作解决方案是通过在表视图中插入正常的单元格，并将它们作为Section Headers处理，但更好的方法是通过在每个Section的第0行插入这些单元格。这样我们就可以很容易地处理这些自定义的非浮动标头。

步骤是。

Implement UITableView with style UITableViewStylePlain. -(void) loadView { [super loadView]; UITableView *tblView =[[UITableView alloc] initWithFrame:CGRectMake(0, frame.origin.y, frame.size.width, frame.size.height-44-61-frame.origin.y) style:UITableViewStylePlain]; tblView.delegate=self; tblView.dataSource=self; tblView.tag=2; tblView.backgroundColor=[UIColor clearColor]; tblView.separatorStyle = UITableViewCellSeparatorStyleNone; } Implement titleForHeaderInSection as usual ( you can get this value by using your own logic, but I prefer to use standard delegates ). - (NSString *)tableView: (UITableView *)tableView titleForHeaderInSection:(NSInteger)section { NSString *headerTitle = [sectionArray objectAtIndex:section]; return headerTitle; } Immplement numberOfSectionsInTableView as usual - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { int sectionCount = [sectionArray count]; return sectionCount; } Implement numberOfRowsInSection as usual. - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { int rowCount = [[cellArray objectAtIndex:section] count]; return rowCount +1; //+1 for the extra row which we will fake for the Section Header } Return 0.0f in heightForHeaderInSection. - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { return 0.0f; } DO NOT implement viewForHeaderInSection. Remove the method completely instead of returning nil. In heightForRowAtIndexPath. Check if(indexpath.row == 0) and return the desired cell height for the section header, else return the height of the cell. - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { if(indexPath.row == 0) { return 80; //Height for the section header } else { return 70; //Height for the normal cell } } Now in cellForRowAtIndexPath, check if(indexpath.row == 0) and implement the cell as you want the section header to be and set the selection style to none. ELSE implement the cell as you want the normal cell to be. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.row == 0) { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"SectionCell"]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"SectionCell"] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; //So that the section header does not appear selected cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"SectionHeaderBackground"]]; } cell.textLabel.text = [tableView.dataSource tableView:tableView titleForHeaderInSection:indexPath.section]; return cell; } else { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleGray; //So that the normal cell looks selected cell.backgroundView =[[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"CellBackground"]]autorelease]; cell.selectedBackgroundView=[[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"SelectedCellBackground"]] autorelease]; } cell.textLabel.text = [[cellArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row -1]; //row -1 to compensate for the extra header row return cell; } } Now implement willSelectRowAtIndexPath and return nil if indexpath.row == 0. This will care that didSelectRowAtIndexPath never gets fired for the Section header row. - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.row == 0) { return nil; } return indexPath; } And finally in didSelectRowAtIndexPath, check if(indexpath.row != 0) and proceed. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.row != 0) { int row = indexPath.row -1; //Now use 'row' in place of indexPath.row //Do what ever you want the selection to perform } }

这样你就完成了。现在，您拥有了一个完美的滚动的、非浮动的节头。

While thinking how to approach this problem, I remembered a very important detail about UITableViewStyleGrouped. The way UITableView implements the grouped style (the rounded borders around the cells) is by adding a custom backgroundView to the UITableViewCells, and not to the UITableView. Each cell is added a backgroundView according to its position in the section (upper rows get the upper part of the section border, middle ones get the side border and the bottom one gets – well, the bottom part). So, if we just want a plain style, and we don’t have a custom backgroundView for our cells (which is the case in 90% of the times), then all we need to do is use UITableViewStyleGrouped, and remove the custom background. This can be done by following those two steps:

将我们的tableView样式改为UITableViewStyleGrouped 在cellForRow返回单元格之前，添加以下一行:

细胞。开源视图=[[UIView alloc]这是一个细胞:跳跃]autorelease];

就是这样。tableView样式将变得完全像UITableViewStylePlain，除了浮动头。

希望这能有所帮助!
