How to hide a section in UITableView?

Question

There are some section in the table that does not contain any data and would like to hide that section.

How to do this?

Answer 1

You can set the particular section rows height to 0. Also, with the section header if you want. Datasource would still be there, only not showing up.

Section Rows

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.section == 0) {
        if (_shouldHidden) {
            return 0.0;
        }
        else {
            return 55.0;
        }
    }
    else {
        return 55.0;
    }
}

Answer 2

I disagree with Tim. We have a way to access any section/row of a table from anywhere in our code and change its .hidden property (and all other properties).

This is the way I usually use:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:2];
[self.SeymourCakesTableView cellForRowAtIndexPath:indexPath].hidden = YES;

Answer 3

It is true that 0 is not a valid height for headers and footers. However, the heights are CGFloat values. You can specify a very small number (I've used 0.1) for the height of the section headers and footers.

Kind of a hack, but it works.

Answer 4

You can't "hide" a section as such, but you can "delete" it from the table view using the deleteSections:withRowAnimation: method. This will remove it from the view, with an optional animation, without affecting your backing data. (You should, however, update the data anyway so that the section doesn't reappear.)

Answer 5

You probably need to remove the section itself from the data backing your table. I don't think there's anything that lets you just hide a section.

Answer 6

You can set the number of rows in that section to 0. However, it will leave a noticeable blank area where it used to be.
