Ios TableView复选标记

ios objective-c uitableview

Ios TableView复选标记,ios,objective-c,uitableview,nsdictionary,Ios,Objective C,Uitableview,Nsdictionary,我想在选择字典数组数据时在tableview中打勾 例如：-数组包含10个模型名（它是字典），它包含子模型 我的问题是，当我选择子模型时，ModelName会自动获得选中标记。 现在我为不同的模型和子模型打勾，但是我们如何基于子模型打勾 我的cellForRow方法 UITableViewCell *cell; cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"]; if (!cell) { cell = [[UITab

我想在选择字典数组数据时在tableview中打勾

例如：-数组包含10个模型名（它是字典），它包含子模型

我的问题是，当我选择子模型时，ModelName会自动获得选中标记。 现在我为不同的模型和子模型打勾，但是我们如何基于子模型打勾

我的
cellForRow
方法

UITableViewCell *cell;
cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];
if (!cell)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"Cell"];
}
UILabel *nameLbl = (UILabel*) [cell.contentView viewWithTag:11];
UILabel *code = (UILabel*) [cell.contentView viewWithTag:12];
UIButton *button = (UIButton*) [cell.contentView viewWithTag:13];
NSInteger index = indexPath.row;
NSDictionary *dictParent = [_data objectAtIndex:indexPath.section];
NSDictionary *dictItem = dictParent;
if (indexPath.row > 0)
{
    // If its not the first row in the section, assume the row is a child row.
    NSArray *arrChildren = [dictParent objectForKey:@"ChildProductModels"];
    // Get child row info
    dictItem = [arrChildren objectAtIndex:indexPath.row ];
}
    nameLbl.text = [dictItem objectForKey:@"Name"];
    code.text = [dictItem objectForKey:@"Code"];
// To display checkmark for selected value
    if (_selectedarray.count == _rowdata.count)
    {
        imagebutton.hidden=NO;
        [headerArray removeAllObjects];
        [headerArray addObject:@"1"];
        UIImage *btnImage = [UIImage imageNamed:@"ic_floating_done_@1x"];
        [button setImage:btnImage forState:UIControlStateNormal];
        [button setBackgroundColor:[UIColor colorWithRed:0/255.0 green:255/255.0 blue:255/255.0 alpha:1.0]];
    }
    else if ([_selectedarray containsObject:[_rowdata objectAtIndex:index]] )
    {
        imagebutton.hidden =NO;
        [headerArray removeAllObjects];
        [headerArray addObject:@"1"];
        UIImage *btnImage = [UIImage imageNamed:@"ic_floating_done_@1x"];
        [button setImage:btnImage forState:UIControlStateNormal];
        [button setBackgroundColor:[UIColor colorWithRed:0/255.0 green:255/255.0 blue:255/255.0 alpha:1.0]];
    }
    else
    {
        imagebutton.hidden=YES;
        cell.accessoryType=UITableViewCellAccessoryNone;
        UIImage *btnImage = [UIImage imageNamed:@""];
        [button setImage:btnImage forState:UIControlStateNormal];
        [button setBackgroundColor:[UIColor whiteColor]];
    }
从上面的代码中，我可以为多重选择打勾。请为我的问题给出一些想法（或）例子

 (
{
 ChildProductModels =     (
        {
    Code = "LB3/7-002";
    Name = "With transport apron 4.5 M";
    ParentChildType = C;
    ParentID = PMD000001;
    ProductID = PRD000004;
    ProductModelID = PMD000003;
},
        {
    Code = "LB3/7-003";
    Name = "With Magnetic Roller";
    ParentChildType = C;
    ParentID = PMD000001;
    ProductID = PRD000004;
    ProductModelID = PMD000004;
  }
);
Code = "LB3/7";
Name = "Mixing Bale Opener LB3/7";
ParentChildType = P;
ParentID = "<null>";
ProductID = PRD000004;
ProductModelID = PMD000001;
},
{
   ChildProductModels =     (
        {
    Code = "LB7/4-001";
    Name = "With Beater";
    ParentChildType = C;
    ParentID = PMD000005;
    ProductID = PRD000004;
    ProductModelID = PMD000006;
  }
  );
  Code = "LB7/4";
 Name = "UNIMIX MODEL LB7/4";
 ParentChildType = P;
 ParentID = "<null>";
  ProductID = PRD000004;
 ProductModelID = PMD000005;
}
)
在上面我的viewForHeader方法中

我的TableviewdidSelect方法

要放置复选标记，可以在复选标记的适当位置放置UIImageView

然后，您可以维护一个选定单元格的数组，其中将包含一个布尔值，isSelected（或任何您认为合适的值）

然后，一旦用户选择了一个单元格，在didSelect委托方法中。只需重新加载rows:atIndexPath即可重新加载单元格。

Im利用“tag”属性轻松访问TableView中的节标题

大概是这样的：
