Ios 默认情况下，设置UiTableView复选框

我想创建一个功能，应用程序应该自动选中uitableview复选标记，并且用户也可以手动选择单元格

#pragma mark - Table View Data Source
   - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)
    indexPath {
        static NSString *unifiedID = @"aCellID";
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:unifiedID];
        if (!cell) {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:unifiedID];
        }

        //if the indexPath was found among the selected ones, set the checkmark on the cell
        cell.accessoryType = ([self isRowSelectedOnTableView:tableView atIndexPath:indexPath]) ? UITableViewCellAccessoryCheckmark : UITableViewCellAccessoryNone;

        [cell.textLabel setText:[categoryList objectAtIndex:indexPath.row]];
        [cell.imageView setImage:[categoryImagesArr objectAtIndex:indexPath.row]];

        return cell;
    }

    //if a row gets selected, toggle checkmark
    -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {
        NSString *catStr = [categoryIdArr objectAtIndex:indexPath.row];
        UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
        if([self isRowSelectedOnTableView:tableView atIndexPath:indexPath]){
            [self.selectedCells removeObject:indexPath];
            [self.selecedcategories removeObject:catStr];
            cell.accessoryType = UITableViewCellAccessoryNone;
        }else{
            [self.selectedCells addObject:indexPath];
            [self.selecedcategories addObject:catStr];
            cell.accessoryType = UITableViewCellAccessoryCheckmark;
        }
    }

    -(BOOL)isRowSelectedOnTableView:(UITableView *)tableView atIndexPath:(NSIndexPath *)indexPath{
        return ([self.selectedCells containsObject:indexPath]) ? YES : NO;
    }

手动选择电池时，此代码正常工作。应选择的电池数据可存储在阵列中。请分享一些想法？

它以以下方式工作。表示只需反转附件类型即可

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)
indexPath {
    static NSString *unifiedID = @"aCellID";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:unifiedID];
    if (!cell) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:unifiedID];
    }

    //if the indexPath was found among the selected ones, set the checkmark on the cell
//    cell.accessoryType = ([self isRowSelectedOnTableView:tableView atIndexPath:indexPath]) ? UITableViewCellAccessoryCheckmark : UITableViewCellAccessoryNone;
//    NSLog(@"yes or no:::%hhd",[self isRowSelectedOnTableView:tableView atIndexPath:indexPath]);

    if ([self isRowSelectedOnTableView:tableView atIndexPath:indexPath])
    {

        cell.accessoryType=UITableViewCellAccessoryNone;

    }
    else{
        cell.accessoryType=UITableViewCellAccessoryCheckmark;

    }


    [cell.textLabel setText:[categoryList objectAtIndex:indexPath.row]];
   // [cell.imageView setImage:[categoryImagesArr objectAtIndex:indexPath.row]];

    return cell;
}

您的复选框编码boss在哪里，请使用allowmultipleselection作为检查位置box@Anbu.Karthikcellforrow中的isRowSelectedOnTableView方法用于单元格检查。如何使用IndExpath预加载self.selectedCells数组？您是否考虑过使用NSMutableIndexSet？@Paulw11 self.selectedcells在用户点击单元格时填充索引。表示只需反转附件类型即可
