如何以编程方式关闭展开的表格视图单元格？

Question

I have two tabs in a view controller: on click of each tab, different data is displayed in a table view with cells that expand and close on click.

The problem is that when I'm in tab A, and expand a cell there, then go and click on tab B, loading new data, that cell is still expanded. How do I close it programatically?

I'm using the FZAccordionTableView subclass to perform the expansions.

- (UIView *)tableView:(FZAccordionTableView *)tableView viewForHeaderInSection:(NSInteger)section {
    HeaderView *view = [tableView dequeueReusableHeaderFooterViewWithIdentifier:kAccordionHeaderViewReuseIdentifier];
    if (listOfCategoryWhichHaveItems.count > 0) {
        if (arrCategory.count > 0) {
            arrCategory1  = _btnProduct.selected == YES ? [arrCategory objectAtIndex:0] : [arrCategory objectAtIndex:1];
            NSDictionary *dict = arrCategory1[section];
            view.lblHeaderTitel.text = [dict valueForKey:kCategory];
            bool isSelected = [tableView isSectionOpen:section];
        }
    }
    return view;
}

#pragma mark - <FZAccordionTableViewDelegate> -

- (void)tableView:(FZAccordionTableView *)tableView willOpenSection:(NSInteger)section withHeader:(UITableViewHeaderFooterView *)header {
    loadFirstTime = false;
    [tableView reloadSections:[NSIndexSet indexSetWithIndex:section] withRowAnimation: UITableViewRowAnimationAutomatic];
    if (listOfCategoryWhichHaveItems.count > 0) {
        _sectionNumber = &section;
        NSDictionary *dict = listOfCategoryWhichHaveItems[section];
        [self setDataAccordingToCategories:[dict valueForKey:kCategory]];
    }
}

- (void)tableView:(FZAccordionTableView *)tableView didOpenSection:(NSInteger)section withHeader:(UITableViewHeaderFooterView *)header {
}

Answer 1

单击选项卡B时，请将表的keepOneSectionOpen属性设置为No。

Yourtable.keepOneSectionOpen = No;

Answer 2

In the FZAccordionTableView GitHub repo i found this method:

- (void)closeSection:(NSInteger)section withHeaderView:(nullable FZAccordionTableViewHeaderView *)sectionHeaderView

That will probably do what you want, it is however not declared in the header file so you can't call it directly.

You can however clone the repo, add the line to the header file, add + commit + push to your fork. Then use that repo in your Podfile (or however you're using the library right now) so you're using your fork of the framework, then you can call the method.

On click of each tab, i used this [_tblProductServies closeAllSectionsExcept:-1]; its working fine now, thanks for all.
