如何在swift中將tableview標題和cellForRowAt從相同的json中分離出來

我想將國家代碼顯示為表格視圖的標題，單擊標題地點后應顯示。我試過了，但我無法達到預期的輸出。

這是我的 json ：

{
  "meetings": [
    {
      "meetingId": 31389393,
      "name": "Ludlow 20th Apr",
      "openDate": "2022-04-20T12:00:00 00:00",
      "venue": "Ludlow",
      "eventTypeId": 7,
      "countryCode": "GB",
      "meetingGoing": "Good"
    },
    {
      "meetingId": 31389469,
      "name": "Catterick 20th Apr",
      "openDate": "2022-04-20T12:40:00 00:00",
      "venue": "Catterick",
      "eventTypeId": 7,
      "countryCode": "GB",
      "meetingGoing": "Good (Good to Soft in places)"
    },
    {
      "meetingId": 31389416,
      "name": "Perth 20th Apr",
      "openDate": "2022-04-20T12:50:00 00:00",
      "venue": "Perth",
      "eventTypeId": 7,
      "countryCode": "GB",
      "meetingGoing": "Good to Soft (Good in places)"
    },
    {
      "meetingId": 31389532,
      "name": "Lingfield 20th Apr",
      "openDate": "2022-04-20T15:15:00 00:00",
      "venue": "Lingfield",
      "eventTypeId": 7,
      "countryCode": "GB",
      "meetingGoing": "Standard"
    },
    {
      "meetingId": 31389447,
      "name": "Salisbury 20th Apr",
      "openDate": "2022-04-20T15:25:00 00:00",
      "venue": "Salisbury",
      "eventTypeId": 7,
      "countryCode": "GB",
      "meetingGoing": "Good to Firm (Good in places)"
    }
  ]
}

這是我用于獲取資料的代碼：

    struct Racing{
        var countryCode:String
        var venue: [String]
        var races: [Races]?
    }
    
    var todayRacingArray = [Racing]()
    APIClient2<RacingListBaseClass>().API_GET(Url: url, Params: noParams, Authentication: false, Progress: false, Alert: true, Offline: false, SuperVC: self, completionSuccess: { (response) in
    for item in response.meetings ?? []
    {
       let cc = item.countryCode
       var venue = [String]()
       ven.append(item.venue ?? "")
       let obj = Racing(countryCode: cc ?? "", venue: venue)
       self.todayRacingArray.append(obj)
    }
    self.otherSportsTableView.reloadData()
 }) { (failed) in
            
        }

表視圖：

func numberOfSections(in tableView: UITableView) -> Int {
    return self.todayRacingArray.count
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int     {
    return self.todayRacingArray[section].venue.count
}

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let cell =  tableView.dequeueReusableCell(withIdentifier: String(describing: HeaderTableViewCell.self)) as! HeaderTableViewCell
    let obj = todayRacingArray[section]
    cell.titleLbl.text = obj.countryCode
    return cell
  }

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell =  tableView.dequeueReusableCell(withIdentifier: String(describing: BodyTableViewCell.self)) as! BodyTableViewCell
    cell.frame = tableView.bounds
    cell.layoutIfNeeded()
    let obj = self.todayRacingArray[indexPath.section].venue[indexPath.row]
    cell.horseTitleLabel.text = obj
    return cell
}

我的輸出 我的表格標題 單擊標題后 我想要這樣的輸出： 在此處輸入影像描述 單擊標題后

請有人幫我解決這個問題。

更新的答案

添加一個新模型RaceVenue。然后像下面這樣修改Racing結構。

struct RaceVanue {
    var venue: String
    var races: [Race]?
}

struct Racing {
    var countryCode:String
    var raceVenues: [RaceVanue]
}

修改countryVenueDict字典的宣告。

var countryVenueDict: [String: [RaceVanue]] = [:]

然后在添加到countryVenueDict字典時修改代碼。然后在添加時也修改賽車模型todayRacingArray

for item in response.meetings ?? []
{
    if let _ = countryVenueDict[item.countryCode ?? ""] {
        countryVenueDict[item.countryCode ?? ""]?.append(RaceVanue(venue: item.venue ?? "", races: item.races))
    } else {
        countryVenueDict[item.countryCode ?? ""] = [RaceVanue(venue: item.venue ?? "", races: item.races)]
    }
}

todayRacingArray  = countryVenueDict.map { Racing(countryCode: $0.key, raceVenues: $0.value) }

上一個答案

在宣告之前添加一個字典來映射venuewithcountrycodetodayRacingArray

var countryVenueDict: [String: [String]] = [:]
var todayRacingArray = [Racing]()

修改 for 回圈中的代碼，如下所示。

for item in response.meetings ?? []
{
    if let _ = countryVenueDict[item.countryCode ?? ""] {
        countryVenueDict[item.countryCode ?? ""]?.append(item.venue ?? "")
    } else {
        countryVenueDict[item.countryCode ?? ""] = [item.venue ?? ""]
    }
}

然后通過使用 map 函式todayRacingArray映射變換來附加 [Racing] 陣列。countryVenueDict

todayRacingArray  = countryVenueDict.map { Racing(countryCode: $0.key, venue: $0.value) }

這是完整的代碼

var countryVenueDict: [String: [String]] = [:]
var todayRacingArray = [Racing]()
APIClient2<RacingListBaseClass>().API_GET(Url: url, Params: noParams, Authentication: false, Progress: false, Alert: true, Offline: false, SuperVC: self, completionSuccess: { (response) in
    for item in response.meetings ?? []
    {
        if let _ = countryVenueDict[item.countryCode ?? ""] {
            countryVenueDict[item.countryCode ?? ""]?.append(item.venue ?? "")
        } else {
            countryVenueDict[item.countryCode ?? ""] = [item.venue ?? ""]
        }
    }
    todayRacingArray  = countryVenueDict.map { Racing(countryCode: $0.key, venue: $0.value) }
    self.otherSportsTableView.reloadData()
}) { (failed) in
    
}
