Change the UITableView's height for HeaderInSection?

My UITableView's style is plain, and I want to change the height of HeaderInSection, but it's remains the default height 22.0.

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    if (tableView.tag == tableOrdersTag)
    {
        return 35;
    }
    else
    {
        return 0;
    }
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    if (tableView.tag == tableOrdersTag)
    {
        UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frameWidth, 35)];

        view.backgroundColor = COMMON_BACKGROUND_COLOR;

        DDLogVerbose(@"=========tableView  %f", tableView.sectionHeaderHeight);

        return view;
    }
    else
    {
        return nil;
    }
}

The place of your NSLog

        DDLogVerbose(@"=========tableView  %f", tableView.sectionHeaderHeight);

may cause the problem.It should's before the return method:

        return view;

change the number 35 to 100, you'll find the it works fine.

because the method of 

tableView:viewForHeaderInSection

is behind of 

tableView:heightForHeaderInSection.

When I create a TaleViewController without xib or storyboard like :

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    NSLog(@"heightForHeaderInSection");
        return 100;
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{

        UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frame.size.width, 100)];

        view.backgroundColor = [UIColor redColor];
        NSLog(@"=========tableView  %f", tableView.sectionHeaderHeight);
        return view;
}

it will print like :

 2015-05-21 18:25:30.525 UITableViewHeaderDemo[24727:2350493] heightForHeaderInSection
 2015-05-21 18:25:30.526 UITableViewHeaderDemo[24727:2350493] heightForHeaderInSection
 2015-05-21 18:25:30.526 UITableViewHeaderDemo[24727:2350493] heightForHeaderInSection
 2015-05-21 18:25:30.526 UITableViewHeaderDemo[24727:2350493] heightForHeaderInSection
 2015-05-21 18:25:30.535 UITableViewHeaderDemo[24727:2350493] heightForHeaderInSection
 2015-05-21 18:25:30.535 UITableViewHeaderDemo[24727:2350493] heightForHeaderInSection
 2015-05-21 18:25:30.549 UITableViewHeaderDemo[24727:2350493] heightForHeaderInSection
 2015-05-21 18:25:30.549 UITableViewHeaderDemo[24727:2350493] heightForHeaderInSection
 2015-05-21 18:25:30.550 UITableViewHeaderDemo[24727:2350493] =========tableView  -1.000000

but the It works fine

Do this things:-

  1. Open interface builder and select table view.
  2. Now, Open the size inspector.
  3. Find options to set section height.
  4. In that, you'll find Header and Footer. Set value of 35 to header.

Try out this. Hope this will solve your problem.

First of all change section height from Xib then

Return following line instead of nil in else then check 

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frameWidth, 0)];
