How to delete sections from static cell tableview - objective-c

Question

I'm trying to delete or hide a section inside a tableview with static cells on it. I am trying to hide it in function viewDidLoad. Here is the code:
- (void)viewDidLoad
{
[super viewDidLoad];
[self.tableView beginUpdates];
[self.tableView deleteSections:[NSIndexSet indexSetWithIndex:1] withRowAnimation:YES];
[self.tableView endUpdates];
[self.tableView reloadData];
}
Still the sections appear. I am using storyboards in it. Can you please help me out?Thanks!

Answer 1

I found it most convenient to hide sections by overriding numberOfRowsInSection.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if ( section == 1 )
// Hide this section
return 0;
else
return [super tableView:self.tableView numberOfRowsInSection:section];
}

Check the answer found here. How to remove a static cell from UITableView using Storyboards Seems to be a bugger of a problem when using static cells. Hope this helps.

Here you go. This one also removes the vertical space.
NSInteger sectionToRemove = 1;
CGFloat distance = 10.0f; // minimum is 2 since 1 is minimum for header/footer
BOOL removeCondition; // set in viewDidLoad
/**
* You cannot remove sections.
* However, you can set the number of rows in a section to 0,
* this is the closest you can get.
*/
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
if (removeCondition && section == sectionToRemove)
return 0;
else
return [super tableView:self.tableView numberOfRowsInSection:section];
}
/**
* In this case the headers and footers sum up to a longer
* vertical distance. We do not want that.
* Use this workaround to prevent this:
*/
- (CGFloat)tableView:(UITableView *)tableView
heightForFooterInSection:(NSInteger)section {
return removeCondition &&
(section == sectionToRemove - 1 || section == sectionToRemove)
? distance / 2
: distance;
}
- (CGFloat)tableView:(UITableView *)tableView
heightForHeaderInSection:(NSInteger)section {
return removeCondition &&
(section == sectionToRemove || section == sectionToRemove + 1)
? distance / 2
: distance;
}

It seems that reloadData makes table view to re-read dataSource. You should also remove data from dataSource before calling reloadData. If you are using array, remove object you want with removeObject: before calling reloadData.
