Is it possible to change section header height depending on section item count? I want to hide section header if there is no items in it. 
I was trying to use something like this


self.tableViewModel.sectionActions.willDeleteItem = ^BOOL(SCArrayOfItemsSection *itemsSection, NSObject *item, NSIndexPath *indexPath) {
        if ([itemsSection.items count] == 1) {
           itemsSection.headerHeight = 0.f;
        return YES;

But it doesn't work.

Thank you in advance!

Hi Kourghan,


Your approach is correct, but there are two issues here:


1. You need to reload the table view whenever you change a section's headerTitle, headerView, headerHeight, etc. This is best done at 'didDeleteItem' instead of 'willDeleteItem'.

2. A headerHeight of zero simply tells STV to automatically calculate the height for whatever you have there. Perhaps we should change the way STV treats a zero headerHeight, and have it do its automatic calculations when headerHeight is -1 for instance. If you must set the headerHeight for now, you can set it to a very small value: 'itemsSection.headerHeight = 0.01f'. Alternatively, you also either set 'itemsSection.headerTitle = nil', or 'itemsSection.headerView = [[UIView alloc] initWithFrame:CGRectZero]'.


Here is a code sample:


self.tableViewModel.sectionActions.didDeleteItem = ^(SCArrayOfItemsSection *itemsSection, NSIndexPath *indexPath)
        if ([itemsSection.items count] == 0) {
            itemsSection.headerHeight = 0.01f;
            [self.tableViewModel.tableView reloadData];



Again, we will update STV very soon so that you could use 'headerHeight = 0.0f' instead (won't make any difference to the end result though). Hope this helps.
