ios - 如何在 NSMutableArray 中添加包含数组的字符串？

Question

我有这个 json

{
    "title": "xyz",
    "category": "Monetary",
    "target": "55",
    "achieve": "0",
    "todolist": [
        {
            "todoitem": "one"
        },
        {
            "todoitem": "two"
        },
        {
            "todoitem": "three"
        }
    ]
}

来自 API，我想将 todolist 数组添加到

在.h文件中

@property (strong, nonatomic) NSMutableArray *todolist;
@property (strong, nonatomic) NSMutableArray *todolists;
@property (strong, nonatomic) NSMutableArray *listnumber;

在.m文件中

todolist=[[NSMutableArray alloc] initWithObjects: nil];
todolists=[[NSMutableArray alloc] initWithObjects: nil];
listnumber=[[NSMutableArray alloc] initWithObjects: nil];

在函数中获取json

    todolists = [result valueForKey:@"todolist"];
             for (int j =0; j < todolist.count; j++)
             {
                 [todolist addObject:[[todolists objectAtIndex:j] valueForKey:@"todoitem"]];
                 [listnumber addObject:[NSString stringWithFormat:@"%d", j]];
             }

             [tvToDoList reloadData];

CellForRowAtIndexPath 我正在为两个字段添加值

            static NSString *CellIdentifier=@"Cell";
            TodolistTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
            if(cell==nil)
            {
                cell = [[TodolistTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier ];
                cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
            }

            int row = (int)[indexPath row];

            cell.valListitem.text  = todolist[row];
            cell.lblNo.text = listnumber[row];


            return cell;
        }

结果包含整个 json

在一行代码中试试这个。

todolist = [[[result valueForKey:@"todolist"] valueForKey:@"todoitem"] mutableCopy];
