如何根据 swift 中的段在表视图中显示 JSON 响应

Question

我调用了 viewcontroller 中的树段。 OPEN, CLOSED, ALL

我的 JSON 回复如下：

{
"jsonrpc": "2.0",
"result": {
    "data": {
        "open": [
            {
                "user_id": "10",
                "request_title": "Title-2",
                "category": "4",
                "gender": "M",
                "location": "On earth",
                "from_date": "2021-04-09",
             }
             {
            "user_id": "10",
            "request_title": "Title-2",
            "category": "4",
            "gender": "M",
            "location": "On earth",
            "from_date": "2021-04-09",
            }
            ........
            ]
        "close": [
            {
                "user_id": "10",
                "request_title": "Title-2",
                "category": "4",
                "gender": "M",
                "location": "On earth",
                "from_date": "2021-04-09",
             }
            ........
            ]
        "all": [
            {
                "user_id": "10",
                "request_title": "Title-2",
                "category": "4",
                "gender": "M",
                "location": "On earth",
                "from_date": "2021-04-09",
             }
             {
            "user_id": "10",
            "request_title": "Title-2",
            "category": "4",
            "gender": "M",
            "location": "On earth",
            "from_date": "2021-04-09",
            }
            ........
            ]
    }
}
}

在这里我能够得到 JSON 响应.. 和低于 i am getting "open" values and adding them in requestsArrayto show in tableview.. but now thisrequestsArraywant to show inopen` 段就像关闭段中相同的关闭值..怎么做

     if let code = ((resp.dict?["result"] as? [String : Any])){
               
                let totalData = code["data"] as? [String : Any]
                if let open = totalData?["open"] as? [[String : Any]]{
                    for (value) in open {
                        self?.title_req = value["request_title"] as? String
                        self?.gender = value["gender"] as? String
                        self?.location = value["location"] as? String
                                                    
            self?.requestsArray.append(AppliedRequestCellData(request_title: self?.title_req, gender: self?.gender, location: self?.location))
                        
            }
        DispatchQueue.main.async {
        self.tableView.reloadData()
    }                }

我的段如下

          hmSegment.indexChangeBlock = { index in
        print("in index segment")
        print(index)
        if index == 0{
          // here how to show JSON `open` response in tableview
           }

        if index == 1{
        // here how to show JSON `close` response in tableview
        }
     if index == 2{
       // here how to show JSON `all` response in tableview
     }


}

请帮我确定 JSON tableviewview 中的响应

Answer 1

创建 4 个数组

var openItems = [AppliedRequestCellData]()
var closedItems = [AppliedRequestCellData]()
var allItems = [AppliedRequestCellData]()

var items = [AppliedRequestCellData]()

items是主数据源数组。

对OPEN、CLOSED、ALL的数据进行解码，赋值给对应的数组

在 indexChangeBlock 中更改主数组的内容并重新加载 table 视图

hmSegment.indexChangeBlock = { index in
    print("in index segment")
    switch index { 
       case 0: self.items = self.openItems
       case 1: self.items = self.closedItems
       case 2: self.items = self.allItems
       default: break
    }
    self.tableView.reloadData()
}

考虑使用 UITableViewDiffableDataSource，它提供了一个很好的变化动画。
还可以考虑使用 Codable 和 JSONDecoder
