I wan to print all the data present inside game data Array

Currently i have the code as this manner:

DataModel :

class WebSiteDataModel: Codable {
    let status: String?
    let data: [Datum]?

    init(status: String?, data: [Datum]?) {
        self.status = status
        self.data = data
    }
}

// MARK: - Datum
class Datum: Codable {
    let siteID: Int?
    let siteCreatedOn: String?
    let siteDown: Int?
    let siteDownFrom, siteDownTo, siteName: String?
    let siteURL: String?
    let instantAccount, status: Int?
    let img: String?
    let gamedata: [Gamedatum]?

    enum CodingKeys: String, CodingKey {
        case siteID = "site_id"
        case siteCreatedOn = "site_created_on"
        case siteDown = "site_down"
        case siteDownFrom = "site_down_from"
        case siteDownTo = "site_down_to"
        case siteName = "site_name"
        case siteURL = "site_url"
        case instantAccount = "instant_account"
        case status, img, gamedata
    }

    init(siteID: Int?, siteCreatedOn: String?, siteDown: Int?, siteDownFrom: String?, siteDownTo: String?, siteName: String?, siteURL: String?, instantAccount: Int?, status: Int?, img: String?, gamedata: [Gamedatum]?) {
        self.siteID = siteID
        self.siteCreatedOn = siteCreatedOn
        self.siteDown = siteDown
        self.siteDownFrom = siteDownFrom
        self.siteDownTo = siteDownTo
        self.siteName = siteName
        self.siteURL = siteURL
        self.instantAccount = instantAccount
        self.status = status
        self.img = img
        self.gamedata = gamedata
    }
}

// MARK: - Gamedatum
class Gamedatum: Codable {
    let gameID, isactive, coins: Int?
    let name: String?
    let status, siteID: Int?

    enum CodingKeys: String, CodingKey {
        case gameID = "game_id"
        case isactive, coins, name, status
        case siteID = "site_id"
    }

    init(gameID: Int?, isactive: Int?, coins: Int?, name: String?, status: Int?, siteID: Int?) {
        self.gameID = gameID
        self.isactive = isactive
        self.coins = coins
        self.name = name
        self.status = status
        self.siteID = siteID
    }
}

Controller:

var newArray = Datum

let url = baseUrl

        APIClient<WebSiteDataModel>().API_GET(Url: url, Params: noParams, Authentication: true, Progress: false, Alert: true, Offline: false, SuperVC: self, completionSuccess:{(modelResponse) in
           
            if let status = modelResponse.status, status == "Success"
            {
                self.newArray = modelResponse.data ?? []
                self.expandableTableView.reloadData()
            }
            else
            {
                
            }
           
        }) {(failed) in
            
        }

TableView:

extension IdsViewController: ExpyTableViewDataSource {
    func tableView(_ tableView: ExpyTableView, expandableCellForSection section: Int) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "ExpandPLTableViewCell") as! ExpandPLTableViewCell
        let obj = newArray[section]
        cell.siteName.text = obj.siteName
        return cell
    }
    
    func tableView(_ tableView: ExpyTableView, canExpandSection section: Int) -> Bool {
        return ExpyTableViewDefaultValues.expandableStatus
    }
}

extension IdsViewController {
    func numberOfSections(in tableView: UITableView) -> Int {
        return newArray.count
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 2
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCell(withIdentifier: String(describing: PLSpecificationTableViewCell.self)) as! PLSpecificationTableViewCell
        let obj = newArray[indexPath.section].gamedata?[indexPath.row]
        print(obj?.name ?? "")
        return cell
    }
}

extension IdsViewController
{
    //Tells the delegate a row is selected.
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
    {
        tableView.deselectRow(at: indexPath, animated: false)
        
        print("DID SELECT row: \(indexPath.row), section: \(indexPath.section)")
    }
    
    //Asks the delegate for the height to use for a row in a specified location.
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat
    {
        
        if indexPath.row != 0 {
            let indexPathRow = self.indexPathRowDetails(indexPath: indexPath)
            
            if indexPath.row % 2 == 0
            {
                if newebsiteArray.isExpanded(section: indexPath.section, row: indexPathRow)
                {
                    return UITableView.automaticDimension
                }
                else
                {
                    return 0
                }
            }
        }
        return UITableView.automaticDimension
    }
}

I want to print all the present in side gamedata Array but getting only one record.Please help me to print all the data

Thank You

CodePudding user response：

First of all declare at least all arrays as non-optional for example

let data: [Datum]

and

let gamedata: [Gamedatum]

and the data source array

var newArray = [Datum]()

Then the table view data source methods are

extension IdsViewController {
    func numberOfSections(in tableView: UITableView) -> Int {
        return newArray.count
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return newArray[section].gamedata.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCell(withIdentifier: String(describing: PLSpecificationTableViewCell.self)) as! PLSpecificationTableViewCell
        let obj = newArray[indexPath.section].gamedata[indexPath.row]
        print(obj.name ?? "")
        return cell
    }
}

Side note: If you are able to add the .convertFromSnakeCase key decoding strategy to your JSONDecoder the Codable classes can be reduced to these structs

struct WebSiteDataModel: Decodable {
    let status: String
    let data: [Datum]
}

// MARK: - Datum
struct Datum: Decodable {
    let siteId: Int
    let siteCreatedOn: String
    let siteDown: Int
    let siteDownFrom, siteDownTo, siteName: String
    let siteUrl: String
    let instantAccount, status: Int
    let img: String
    let gamedata: [Gamedatum]
}

// MARK: - Gamedatum
struct Gamedatum: Decodable {
    let gameId, isactive, coins: Int
    let name: String
    let status, siteId: Int
}

And you should consider the case if status is not "Success"
