通过取两个具有相同日期的对象来过滤对象数组

时间：2018-05-30 09:33:44

标签： ios swift

我试图在某些条件下过滤对象数组：

filtered_shifts = myShifts.filter{$0.regionName == region && $0.cityName == city && $0.idNationality == idn && $0.quantityStaff != 0 && $0.shiftDate > todaydate}

我想更多地过滤它，如果有一个shiftType ==“night”和shiftType ==“day”为同一个shiftDate然后添加到我的过滤的移位数组。

  

如果相同日期有shift类型= day AND type = night，则将其添加到我的过滤数组

我怎样才能实现这一目标？

例如

让我们说

   myShifts = {
       "id": 50,
        "id_region": 1,
        "id_city": 2,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "day",
        "weekday": "wed",
        "quantity_staff": 5,
        "lead_hours": 3,
        "created_at": "2018-05-13 16:27:21",
        "updated_at": "2018-05-13 16:27:21",
        "deleted_at": null,
        "city_name": "Khobar",
        "region_name": "Eastren"
    },
    {
        "id": 70,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "day",
        "weekday": "wed",
        "quantity_staff": 12,
        "lead_hours": 3,
        "created_at": "2018-05-21 14:03:02",
        "updated_at": "2018-05-21 14:03:02",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    },
    {
        "id": 74,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "night",
        "weekday": "wed",
        "quantity_staff": 20,
        "lead_hours": 3,
        "created_at": "2018-05-21 14:40:56",
        "updated_at": "2018-05-21 14:40:56",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    },
    {
        "id": 4,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 4,
        "id_service": 1,
        "shift_date": "2018-05-15 00:00:00",
        "shift_type": "night",
        "weekday": "tue",
        "quantity_staff": 5,
        "lead_hours": 2,
        "created_at": "2018-04-23 11:46:20",
        "updated_at": "2018-05-15 10:33:29",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    }

我想：

 filtered_Shifts =  {
        "id": 70,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "day",
        "weekday": "wed",
        "quantity_staff": 12,
        "lead_hours": 3,
        "created_at": "2018-05-21 14:03:02",
        "updated_at": "2018-05-21 14:03:02",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    },
    {
        "id": 74,
        "id_region": 1,
        "id_city": 1,
        "id_nationality": 3,
        "id_service": 1,
        "shift_date": "2018-06-06 00:00:00",
        "shift_type": "night",
        "weekday": "wed",
        "quantity_staff": 20,
        "lead_hours": 3,
        "created_at": "2018-05-21 14:40:56",
        "updated_at": "2018-05-21 14:40:56",
        "deleted_at": null,
        "city_name": "Dammam",
        "region_name": "Eastren"
    },

在2018-06-06日期，有shift_type = night AND day ...
