带Json的UITableViewController

Question

我正在尝试使用Json响应来填充tableview这是我从回调中读取的Json

user.plan_dates

这是我的代码，但它打破了应用程序的任何想法，我如何更改我的代码，以使其填充tableview与其对应的部分和每个部分中的行

user.plan_dates.where(attribute: test)

这是我的两个对象分支.m部分

{
            "Categories": {
                "Beer": [
                    {
                        "id": "3",
                        "nombre": "Bud ligth",
                        "precio": "10",
                        "categoriaid": "3",
                        "url": "false"
                    }
                ],
                "Whiskey": [
                    {
                        "id": "2",
                        "nombre": "Red label",
                        "precio": "100",
                        "categoriaid": "2",
                        "url": "false"
                    }
                ]
            }
        }

你正在以错误的方式解析json响应， 试试这个，

SELECT 
            e.EmpName,
            d.DepartmentName,
            l.EnrollNumber,
            v.VerifyModeName,
            CAST(PunchTime as DATE)Check_Date,MIN(CAST(PunchTime as Time))[TimeIN], MAX(Cast(PunchTime as Time))[TimeOUT],
                RIGHT('0' + CAST(DATEDIFF(SECOND, MIN(CAST(PunchTime as Time)), MAX(Cast(PunchTime as Time))) / 3600 AS VARCHAR),2) + ':' +
                RIGHT('0' + CAST((DATEDIFF(SECOND, MIN(CAST(PunchTime as Time)), MAX(Cast(PunchTime as Time))) / 60) % 60 AS VARCHAR),2)  + ':' +
                RIGHT('0' + CAST(DATEDIFF(SECOND, MIN(CAST(PunchTime as Time)), MAX(Cast(PunchTime as Time))) % 60 AS VARCHAR),2) as Duration
        FROM Department d    
        INNER JOIN Employee e
            ON e.DeptID = d.Id
        LEFT JOIN AttLog l 
            ON e.EnrollNumber = l.EnrollNumber
        LEFT JOIN VerifyModes v
            ON l.VerifyMode = v.VerifyModeId 
        WHERE cast(l.PunchTime as Date) between '2015-07-22' and '2015-07-22'
        GROUP BY 
            e.EmpName, d.DepartmentName, l.EnrollNumber, v.VerifyModeName, CAST(PunchTime as DATE)

        ORDER BY Check_Date

使用NSDictionary *json = [NSJSONSerialization JSONObjectWithData:self.menuInfo options:NSJSONReadingMutableContainers error:nil]; NSDictionary *cat = [json objectForKey:@"Categories"]; NSMutableArray *categoryArray = [NSMutableArray new]; for(NSString *key in [cat allKeys]){ Categorias *category = [[Categorias alloc]initWithNombre:key]; NSArray *listTagDict = [cat objectForKey:key]; for (NSDictionary *prod in listTagDict) { NSString* pID = [prod objectForKey:@"id"]; NSString* pNombre = [prod objectForKey:@"nombre"]; NSString* pPrecio = [prod objectForKey:@"precio"]; NSString* pUrl = [prod objectForKey:@"url"]; Productos* productos = [[Productos alloc]initWithNombre:pNombre productoID:pID precio:pPrecio iconUrl:pUrl]; [category addRow:productos]; } [categoryArray addObject:category]; } 填充tableview。 在此，categoryArray计数将是节数，每个节包含每个类别categoryArray数组的行。
