You should be able to fake this by using a custom cell to do your header rows. These will then scroll like any other cell in the table view.

You just need to add some logic in your <code>cellForRowAtIndexPath</code> to return the right cell type when it is a header row. 

You'll probably have to manage your sections yourself though, i.e. have everything in one section and fake the headers. (You could also try returning a hidden view for the header view, but I don't know if that will work)

Ignore XAK. Do not explore any private methods if you want your app to have the chance of being accepted by apple.

This is easiest if you are using Interface Builder. You would add a UIView at the top of the view (where the images will go), then add your tableview below that. IB should size it accordingly; that is, the top of the tableview touches the bottom of the UIView you've just added and it's height covers the rest of the screen.

The thinking here is that if that UIView is not actually part of the table view, it will not scroll with the tableview. i.e. ignore the tableview header.

If you're not using interface builder, it's a little more complicated because you've got to get the positioning and height correct for the tableview.

A probably easier way to achieve this:
Objective-C:
<pre><code>CGFloat dummyViewHeight = 40;
UIView *dummyView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.bounds.size.width, dummyViewHeight)];
self.tableView.tableHeaderView = dummyView;
self.tableView.contentInset = UIEdgeInsetsMake(-dummyViewHeight, 0, 0, 0);
</code></pre>
Swift:
<pre><code>let dummyViewHeight = CGFloat(40)
self.tableView.tableHeaderView = UIView(frame: CGRect(x: 0, y: 0, width: self.tableView.bounds.size.width, height: dummyViewHeight))
self.tableView.contentInset = UIEdgeInsets(top: -dummyViewHeight, left: 0, bottom: 0, right: 0)
</code></pre>
Section headers will now scroll just like any regular cell.

blocks|key|1514559|text|虽然这可能不能解决你的问题，但当我想做类似的事情时，它确实解决了我的问题。我没有设置页眉，而是使用了上面部分的页脚。救了我的是，这个部分很小，本质上是静态的，所以它从来不会滚动到视图底部以下。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1514560|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Although this may not solve your problem, it did for me when I wanted to do a similar thing. Instead of setting the header I used the footer of the section above. What saved me was that this section was small and static in nature, so it never scrolled below the bottom of the view.

blocks|key|1299828|text|这可以通过在UITableViewController的viewDidLoad方法中手动分配标题视图来实现，而不是使用委托的viewForHeaderInSection和heightForHeaderInSection。例如，在UITableViewController的子类中，您可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1299829|-+(void)viewDidLoad+{

This can be achieved by assigning the header view manually in the UITableViewController's viewDidLoad method instead of using the delegate's viewForHeaderInSection and heightForHeaderInSection. For example in your subclass of UITableViewController, you can do something like this:

<pre><code>- (void)viewDidLoad {
 [super viewDidLoad];

 UILabel *headerView = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 0, 40)];
 [headerView setBackgroundColor:[UIColor magentaColor]];
 [headerView setTextAlignment:NSTextAlignmentCenter];
 [headerView setText:@"Hello World"];
 [[self tableView] setTableHeaderView:headerView];
}
</code></pre>

The header view will then disappear when the user scrolls. I don't know why this works like this, but it seems to achieve what you're looking to do.

blocks|key|1299960|text|在思考如何解决这个问题时，我想起了关于UITableViewStyleGrouped的一个非常重要的细节。UITableView实现分组样式(单元格周围的圆角边框)的方式是向UITableViewCells而不是UITableView添加自定义backgroundView。每个单元格都会根据它在区域中的位置添加一个backgroundView+(上面的几行获取区域边界的上半部分，中间的几行获取侧面的边界，下面的几行获取-好吧，就是底部)。因此，如果我们只想要一个普通的样式，而我们的单元格没有自定义的backgroundView+(+90%25的情况都是这样)，那么我们所需要做的就是使用UITableViewStyleGrouped，并删除自定义背景。这可以通过以下两个步骤来完成：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1299961|将我们的tableView样式更改为UITableViewStyleGrouped在返回单元格之前将以下行添加到cellForRow：|1299962|cell.backgroundView=[[UIView+alloc+initWithFrame:cell.bounds]自动释放]；|1299963|就是这样。除了浮动标头之外，tableView样式将变得与UITableViewStylePlain完全相同。|1299964|希望这能有所帮助！|1299965|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

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:

Change our tableView style to UITableViewStyleGrouped
Add the following line to cellForRow, just before we return the cell:

cell.backgroundView=[[[UIView alloc] initWithFrame:cell.bounds] autorelease];

And that’s it. The tableView style will become exactly like UITableViewStylePlain, except for the floating headers.

Hope this helps!

To disable floating but still show section headers you can provide a custom view with its own behaviours.

blocks|key|1300065|text|另一种方法是在您想要的标题之前创建一个空节，并将您的标题放在该节上。由于该部分为空，因此标题将立即滚动。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1300066|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I have another even simpler solution, to be used without autolayout and with everything done through the XIB :

1/ Put your header in the tableview by drag and dropping it directly on the tableview.

2/ In the Size Inspector of the newly made header, just change its autosizing : you should only leave the top, left and right anchors, plus the fill horizontally.

There is another tricky way. The main idea is to double the section number, and first one only shows the headerView while the second one shows the real cells.

<pre><code>- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
 return sectionCount * 2;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
 if (section%2 == 0) {
 return 0;
 }
 return _rowCount;
}
</code></pre>

What need to do then is to implement the headerInSection delegates:

<pre><code>- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
 if (section%2 == 0) {
 //return headerview;
 }
 return nil;
}

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
 if (section%2 == 0) {
 //return headerheight;
 }
 return 0;
}
</code></pre>

This approach also has little impact on your datasources:

<pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
 int real_section = (int)indexPath.section / 2;
 //your code
}
</code></pre>

Comparing with other approaches, this way is safe while not changing the frame or contentInsets of the tableview.
Hope this may help.

Maybe you can simply make header view background transparent:

<pre><code>- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
 view.tintColor = [UIColor clearColor];
}
</code></pre>

Or apply it globally:

<pre><code> [UITableViewHeaderFooterView appearance].tintColor = [UIColor clearColor];
</code></pre>

blocks|key|1300843|text|也许您可以在tableView上使用scrollViewDidScroll，并根据当前可见的标头更改contentInset。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1300844|它似乎适用于我的用例！|1300845|extension+ViewController+:+UIScrollViewDelegate{

Maybe you could use <code>scrollViewDidScroll</code> on the tableView
and change the <code>contentInset</code> based on the current visible header.

It seems to work for my use case!

<pre><code>extension ViewController : UIScrollViewDelegate{

 func scrollViewDidScroll(_ scrollView: UIScrollView) {
 guard let tableView = scrollView as? UITableView,
 let visible = tableView.indexPathsForVisibleRows,
 let first = visible.first else {
 return
 }

 let headerHeight = tableView.rectForHeader(inSection: first.section).size.height
 let offset = max(min(0, -tableView.contentOffset.y), -headerHeight)
 self.tableView.contentInset = UIEdgeInsetsMake(offset, 0, -offset, 0)
 }
}

According to @samvermette's answer，I've implemented the above code in Swift to make it easy for coders to use swift.

<pre><code>let dummyViewHeight = CGFloat(40)
self.tableView.tableHeaderView = UIView(frame: CGRect(x: 0, y: 0, width: self.tableView.bounds.size.width, height: dummyViewHeight))

The snippet display a sticky header only for the first section. Others section headers will float with a cells.

blocks|key|1301014|text|一种巧妙的方法是为header添加一个空节。因为区段没有单元格，所以它根本不会浮动。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1301015|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

A tricky way is add an empty section for header. Because section has no cell, it will not floating at all.

I'm using a <code>UITableView</code> to layout content 'pages'. I'm using the headers of the table view to layout certain images etc. and I'd prefer it if they didn't float but stayed static as they do when the style is set to <code>UITableViewStyleGrouped</code>.

Other then using <code>UITableViewStyleGrouped</code>, is there a way to do this? I'd like to avoid using grouped as it adds a margin down all my cells and requires disabling of the background view for each of the cells. I'd like full control of my layout. Ideally they'd be a "UITableViewStyleBareBones", but I didn't see that option in the docs...
