Ios 在UITableView的部分中添加小节

搜索了很多，但都是徒劳的。我有一个嵌套的

NSMutableArray

的

NSMutableDictionary

。我希望在

UITableView

的节中有节。以下是我的阵列：

    <__NSArrayM 0x7ffe4267efb0>(
{
    "group_title" = "Seller Information";
    "group_values" =     (
                {
            key = "First Name";
            value = test;
        },
                {
            key = "Last Name";
            value = testl;
        }
    );
},
{
    "group_title" = "Buyer Information";
    "group_values" =     (
                {
            key = "First Name";
            value = Demo1;
        },
                {
            key = "Last Name";
            value = Demo;
        }
    );
},
{
    "group_title" = "Transaction Information";
    "group_values" =     (
                {
            key = Status;
            value = Active;
        },
                {
            key = "MLS #";
            value = "15-284";
        },
                {
            key = Address;
            value = "1101 Fargo Ave";
        },
                {
            key = County;
            value = Dickinson;
        },
                {
            key = Zipcode;
            value = 51360;
        },
                {
            key = Contingencies;
            value =             (
                                {
                    key = "General Inspection";
                    value =                     (
                                                {
                            key = "Contingency Verbiage";
                            value = "Inspection Results and balance of this paragraph";
                        }
                    );
                },
                                {
                    key = "New Construction";
                    value =                     (
                                                {
                            key = "Contingency Group";
                            value = "If Required";
                        },
                                                {
                            key = "Days Until Due";
                            value = 5;
                        }
                    );
                }
            );
        }
    );
}
)

我知道我只需要将子部分作为单元进行操作，但不确定如何操作

如何访问

CellForRowatineXpath

中的子部分

---

请帮忙。我如何解决和实施这个问题

您可以使用delegate方法

indentationlevelforrowatinexpath

向单元格添加缩进级别，因此如果要显示子节，只需返回一个

NSInteger

值，例如1，返回值表示指定行的深度，以显示其在节中的层次位置

到目前为止，返回值应该是

  Contingencies // sub-section title - 1
     General Inspection // sub-sub-section title - 2
       Contingency Verbiage  //value - 3
     New Construction // sub-sub-section title - 2
       Contingency Group  //value - 3
       Days Until Due    //value - 3

添加示例代码

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
        //Set the indentation width, so that each indentation level width will increase by it.
        cell.indentationWidth = 5;

        //Show the value from corresponding indexPath
 NSArray *arr = [[dictData valueForKey:@"group_values"] objectAtIndex:indexPath.section];
NSMutableArray *items = [NSMutableArray arrayWithArray:arr];
// For second level section headers
    for (id row  in arr) {
        if([[row objectForKey:@"value"] isKindOfClass:[NSMutableArray class]]) {
            [items addObjectsFromArray:[row valueForKey:@"value"]];
        }
    }
NSDictionary *item = items[indexPath.row]
        cell.textLabel.text = item[@"key"];

        return cell;

    }
    - (NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath {

        //Retrive the right indentation for item at indexPath
 NSArray *arr = [[dictData valueForKey:@"group_values"] objectAtIndex:indexPath.section];
if (indexPath.row < arr.count) {
return 0
}
// For second level section headers
return 1
    }

-（UITableViewCell*）tableView:（UITableView*）tableView cellForRowAtIndexPath:（NSIndexPath*）indexPath{
UITableViewCell*cell=[tableView dequeueReusableCellWithIdentifier:@“cell”forIndexPath:indexPath]；
//设置缩进宽度，使每个缩进级别的宽度增加一倍。
cell.indicationwidth=5；
//显示来自相应索引XPath的值
NSArray*arr=[[dictData valueForKey:@“group_values”]objectAtIndex:indexPath.section]；
NSMUTABLEARRY*项=[NSMUTABLEARRY arrayWithArray:arr]；
//对于第二级节标题
用于（arr中的id行）{
如果（[[row objectForKey:@“value”]是KindofClass:[NSMutableArray类]]）{
[items addObjectsFromArray:[行值forkey:@“值”]；
}
}
NSDictionary*item=items[indexPath.row]
cell.textlab.text=项[@“键”]；
返回单元；
}
-（NSInteger）tableView:（UITableView*）tableView indentationLevelForRowAtIndexPath:（nsindepath*）indepath{
//在indexPath处检索项的正确缩进
NSArray*arr=[[dictData valueForKey:@“group_values”]objectAtIndex:indexPath.section]；
if（indexPath.row

谢谢，但是我应该在

cellforrowatinexpath

中为小节写些什么呢？您不必在

cellforrowatinexpath

中做任何特定的操作，因为

indentationlevelforrowatinexpath

将根据定义的小节对单元格进行缩进。您能给我一些示例代码吗？我不知道如何在我的代码中包含这一点。我已经在问题中给出了我的代码。

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
        //Set the indentation width, so that each indentation level width will increase by it.
        cell.indentationWidth = 5;

        //Show the value from corresponding indexPath
 NSArray *arr = [[dictData valueForKey:@"group_values"] objectAtIndex:indexPath.section];
NSMutableArray *items = [NSMutableArray arrayWithArray:arr];
// For second level section headers
    for (id row  in arr) {
        if([[row objectForKey:@"value"] isKindOfClass:[NSMutableArray class]]) {
            [items addObjectsFromArray:[row valueForKey:@"value"]];
        }
    }
NSDictionary *item = items[indexPath.row]
        cell.textLabel.text = item[@"key"];

        return cell;

    }
    - (NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath {

        //Retrive the right indentation for item at indexPath
 NSArray *arr = [[dictData valueForKey:@"group_values"] objectAtIndex:indexPath.section];
if (indexPath.row < arr.count) {
return 0
}
// For second level section headers
return 1
    }
