If you have a single header in the table then you can use tableHeaderView as below: tableView. tableHeaderView = Header; Or if you have multiple header in table than you need to use Group table instead of plain table.
UITableView scrolls back because it's content size is equal to it's frame (or near to it). If you want to scroll it without returning you need add more cells: table view content size will be large then it's frame.
To scroll to the top of our tableview we need to create a new IndexPath . This index path has two arguments, row and section . All we want to do is scroll to the top of the table view, therefore we pass 0 for the row argument and 0 for the section argument. UITableView has the scrollToRow method built in.
The way I solved this problem is to adjust the contentOffset
according to the contentInset
in the UITableViewControllerDelegate
(extends UIScrollViewDelegate
) like this:
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
CGFloat sectionHeaderHeight = 40;
if (scrollView.contentOffset.y<=sectionHeaderHeight&&scrollView.contentOffset.y>=0) {
scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);
} else if (scrollView.contentOffset.y>=sectionHeaderHeight) {
scrollView.contentInset = UIEdgeInsetsMake(-sectionHeaderHeight, 0, 0, 0);
}
}
Only problem here is that it looses a little bit of bounce when scrolling back to the top.
{NOTE: The "40" should be the exact height of YOUR section 0 header. If you use a number that is bigger than your section 0 header height, you'll see that finger-feel is affected (try like "1000" and you'll see the bounce behaviour is sort of weird at the top). if the number matches your section 0 header height, finger feel seems to be either perfect or near-perfect.}
You can also add a section with zero rows at the top and simply use the footer of the previous section as a header for the next.
Were it me doing this, I'd take advantage of the fact that UITableViews in the Plain style have the sticky headers and ones in the Grouped style do not. I'd probably at least try using a custom table cell to mimic the appearance of Plain cells in a Grouped table.
I haven't actually tried this so it may not work, but that's what I'd suggest doing.
I know it comes late, but I have found the definitive solution!
What you want to do is if you have 10 sections, let the dataSource return 20. Use even numbers for section headers, and odd numbers for section content. something like this
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (section%2 == 0) {
return 0;
}else {
return 5;
}
}
-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
if (section%2 == 0) {
return [NSString stringWithFormat:@"%i", section+1];
}else {
return nil;
}
}
Voilá! :D
Originally posted Here, a quick solution using the IB. The same can be done programmatically though quite simply.
A probably easier way to achieve this (using IB):
Drag a UIView onto your TableView to make it its header view.
- Set that header view height to 100px
- Set the tableview contentInset (top) to -100
- Section headers will now scroll just like any regular cell.
Some people commented saying that this solution hides the first header, however I have not noticed any such issue. It worked perfectly for me and was by far the simplest solution that I've seen so far.
