iOS UITableView Hide Header Space

Question

In a view controller I have only a UITableView. In IB I have made Header & Footer height as 1, and have also added the following code but yet above the 1st cell their is lots of space of header. I want to get rid of that space. Even the scrollbar starts from the 1st cell and not on top.

-(CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
CGFloat height = 0.0001;
return height;
}

-(CGFloat) tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
CGFloat height = 0.0001;
return height;
}

-(UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
// Create Empty View
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.frame.size.width,
                                                        [self tableView:self.visitorlistsTv heightForHeaderInSection:section]) ];
return view;
}

-(UIView *) tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
// Create Empty View
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.view.frame.size.width,
                                                        [self tableView:self.visitorlistsTv heightForFooterInSection:section]) ];
return view;

}

With the above code, the footer part is hidden. But can't get the header hidden too.

Looking at other links for solution I have also added TableView in a View, have added constraints to the tableview, but still the header part is still their.

Where am I going wrong ? How to get rid of it ?

Why do you need a header & footer with such a small height? This looks like a pretty bad hack. What problem do you want to solve? — Rinat Khanov, Aug 05 '14 at 16:04
I read that returning 0 in height doesn't make any difference, hence I tried returning such small header. On top of table above first cell, their is empty space, I want to remove that space. — Tvd, Aug 05 '14 at 16:07

If you're trying to remove the space above your UITableView, try changing it's contentInset property instead of making a custom header with small height:

self.tableView.contentInset = UIEdgeInsetsMake(-20.0f, 0.0f, 0.0f, 0.0f);

You may want to tweak the first number to adjust it to your specific view scene.

Understand that this is also a workaround (source), but it's more clean method than creating a custom table view header.

Thanks that worked. I had added that line, I changed 1st para to -20 and then could see the changes. I had to go till -60 to remove it completely. Any idea why and what is that space for ? – Tvd Aug 05 '14 at 16:15
My table is not grouped also - Style in IB is Plain and not Grouped. – Tvd Aug 05 '14 at 16:17

I have another solution for this (checked on iOS 10), for me the accepted solution didn't work.

In my case, I had variable height section headers, so returning 0 height for first section was not acceptable. I used grouped table style because I needed the separators to frame the section headers too.

Solution: be sure you don't have something like this anywhere in your code:

self.table.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

I used this to remove the separators for the empty rows, but with grouped style that is not necessary.

I know this won't be the case for all of you, but it might help for those in my situation.

It seems to me the problem here is that you don't want a header/footer at all in your view. If this is the case, you don't want to return any view in the header/footer. I would recommend either returning nil in the viewForHeader/Footer or not implementing those functions altogether - they are optional.

Yes I don't want Header/Footer totally. But not implementing or returning 0 and nil in height/viewFor methods made no difference in header. With Footer it works. For Header its only setting contentInset worked. Rest nothing worked for header part. – Tvd Aug 05 '14 at 16:49
I would try removing those altogether from the code, and perhaps try to fix in in IB? – Mike Aug 05 '14 at 17:05
I totally agree with you. I tried that way too. After spending so much time on it, I asked here. – Tvd Aug 05 '14 at 17:18

With Navigationbar you can change the Top values

self.tableView.contentInset =UIEdgeInsetsMake(<#CGFloat top#>, <#CGFloat left#>, <#CGFloat bottom#>, <#CGFloat right#>)

self.tableView.contentInset = UIEdgeInsetsMake(-75.0f, 0.0f, 0.0f, 0.0f);

If you want to avoid setting hard coded height, you can just set the contentOffset top from your first cell Y position like this:

- (void)viewDidLayoutSubviews
{
  UITableViewCell *firstCell = (self.tableView.visibleCells.count > 0?self.tableView.visibleCells[0]:nil);

  [super viewDidLayoutSubviews];

  // Get rid of the defaut header height.
  self.tableView.contentInset = UIEdgeInsetsMake(-firstCell.frame.origin.y, 0, 0, 0);
}

Use this code for removing space between first cell of uitableview.

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
 {
    return 0.002f;// set this...
 }
