Swift 3：使用ID和重新加载tableview筛选结果

问题描述：

我想弄清楚如何筛选数据并重新加载tableview。Swift 3：使用ID和重新加载tableview筛选结果

我有4个地区（北，南，东，西）和所有。

默认情况下，它将显示所有配置文件。

如果我按北（即1），它应该只过滤在北方地区

同样可用配置文件，与南部，东部和西部。根据按下的区域，它应该过滤配置文件。

请看截图：

而且，在第二截图（南区）看到的轮廓是为了隐藏，因为它属于北地区。

请让我知道我该如何解决这个问题。

JSON数据：（REGION_ID）

你可以添加你的类别模型吗？ – Jaydeep

如何识别哪个配置文件属于哪个区域？ – Surjeet

代码中的哪个位置可以设置regId的值？ –

答

1）他们应该是2个不同的阵列。

var mainArray = [StorageSubCatagories]() 
var filteredArray = [StorageSubCatagories]()

第一个数组具有所有对象。（mainArray）

第二个数组只有主数组的过滤对象。（filteredArray）

2）您应该使用普通类，如 'StorageSubCatagories'分析所有的数据，而不是使用像StorageSubCatagoriezTwo，StorageSubCatagoriezTwoNorth，StorageSubCatagoriezTwoEast ...等多个类，存储中的所有对象成一个单一的阵列象下面这样：

3）该函数将返回根据按钮选择滤波的数据。对于按钮全部通过regionId = 0，对于北部regionId = 1，....根据您的值。

func fetchResultForSelection(_ regionId: Int) -> [StorageSubCatagories] { 
     if regionId == 0 { 
      return mainArray 
     } 
     let tempArray = mainArray.filter { $0.regId == regionId } 
     return tempArray 
    }

删除先前的对象后，将从此函数返回的数组对象添加到filteredArray中。

4）始终根据filteredArray而不是mainArray显示您的表数据。

希望这对你有所帮助。

谢谢Surjeet。我会试试这个。让我们看看 –

嘿，我试过了你推荐的解决方案，但显然它还没有工作。 –

你从这个func fetchResultForSelection收到了多少个对象？ – Surjeet
