Chcę zmienić konkretny widok nagłówka mojego UITableView po kliknięciu wiersza.

Przeczytałemwszystko posty na ten temat. Próbowałem „reloadData”, „setNeedDisplay”, „reloadSections: withRowAnimation:” i kilka innych pomysłów ... nie ma nic do zrobienia. Mój widok nagłówka albo się nie aktualizuje, albo robi dziwne rzeczy, takie jak aktualizacja tylko wtedy, gdy przenoszę widok tabeli (co nie jest tym, co chcę osiągnąć).

Mój kod wygląda teraz tak (w odniesieniu do metod delegatów UITableView):

-(NSInteger)numberOfSectionsInTableView:(UITableView*)tableView {
    if(tableView==_storeTableView){
        return [_storeDataArray count];
    } else {
        return 1;
    }
}

-(UIView*)tableView:(UITableView*)tableView viewForHeaderInSection:(NSInteger)section {
    if(tableView==_storeTableView){
        HouraStoreHeaderModel *headerModel = [self.headerInfoArray objectAtIndex:section];
        if (!headerModel.headerView) {
            NSString *shelfName = headerModel.shelf;
            headerModel.headerView = [[[HouraStoreHeaderView alloc] initWithFrame:CGRectMake(0.0, 0.0, _storeTableView.bounds.size.width, 80) title:shelfName section:section subheaderNumber:([headerModel.openedSubHeaders count]-1) delegate:self] autorelease];
        }
        return headerModel.headerView;
    } else {
        return nil;
    }
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    if(tableView==_storeTableView){
        HouraStoreHeaderModel *headerModel = [self.headerInfoArray objectAtIndex:section];
        NSDictionary *myDict = _storeDataDict;
        for (NSInteger i = 0; i < [headerModel.openedSubHeaders count]; i++) {
            myDict = [myDict objectForKey:[headerModel.openedSubHeaders objectAtIndex:i]];
        }
        NSInteger numberOfRowsInSection = [[myDict allKeys] count];
        return headerModel.open ? numberOfRowsInSection : 0;
    } else if(tableView==_searchTableView){
        return [_resultArray count];
    } else {
        return 0;
    }
}

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }

        return cell;
    } else if (tableView==_searchTableView) {
        cell.textLabel.text = [_resultArray objectAtIndex:indexPath.row];

    }

Chciałbym po kliknięciu wiersza zaktualizować nagłówek sekcji, aby zawierał nowy przycisk z tekstem wiersza. Następnie odrzucam wiersz i przeładowuję nowe dane w wierszach sekcji. Udało mi się doskonale obsłużyć rzędy. Ale nie mogę znaleźć sposobu, aby zaktualizować ten widok nagłówka.

Thx za każdy pomysł.
