homeAction 使用到列表翻页的时候，不适合重复调用homeAction

大神考虑到列表翻页的功能吗？homeAction在翻页的时候无法进行复用哦。重复调用HomeAction会直接崩溃。

为什么列表没任何展示呢？纳闷了

我的代码如下，但是列表就是没有数据展示？实在不解

class ViewController: UIViewController{
    
    var viewModel : MyViewModel? = MyViewModel()
    let disposeBag = DisposeBag()
    
    var tableView : UITableView! = {
        
       var tableView = UITableView(frame: UIScreen.main.bounds, style: .plain)
        tableView.rowHeight     = 44.0
        tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
        tableView.tableFooterView = UIView()
     
        return tableView
    }()
    

    override func viewDidLoad() {
        super.viewDidLoad()
        
        view.addSubview(tableView)
      
        
        self.viewModel?
            .homeAction?
            .execute(())
            .bind(to: tableView.rx.items(cellIdentifier: "cell", cellType: UITableViewCell.self)){
                index, model, cell in

                cell.textLabel?.text = model.nick_name
            }
            //.disposed(by:disposeBag)
        
    }

   var homeAction: Action<Void, [BaseUser]>?
    let model = Model()
    var data: [BaseUser]?
    
    init() {
        
        initialize()
    }
    
    
    func initialize() {
        
        homeAction = Action<Void, [BaseUser]>.init(workFactory: {[unowned self] in
            
            var params : Dictionary<String, Any> = [:]
            params["lp"]            = ""
            params["page"]          = "1"
            params["age_min"]       = "-1"
            params["age_max"]       = "-1"
            params["height_min"]    = "-1"
            params["height_max"]    = "-1"
            params["prov"]          = ""
            params["city"]          = ""
            params["user_id"]       = "1"
            
            
           return self.model.request(UserAPI.homeList(params), Msg<BaseUser>.self)
                    .debug()
                    .map{$0.list ?? []}
                    .do(onNext: {
                        self.data = $0
                    })
        })

请教一个问题HandyJSON解析的问题

接口中除了解析到[Storie]数组外，一般接口中都返回code,msg等额外信息，如何解析呢？每个接口都弄一个包含相同code,msg+额外Obj,感觉这样也不现实。

项目中最外层结构大致如下：

class Msg : HandyJSON {
    
    var code : Int?   = 0
    var msg : String?  = ""
    var obj : HandyJSON?
    var list : [HandyJSON]?
    
    required init() {
        
    }
}

  homeAction = Action<Void, [Storie]>.init(workFactory: {[unowned self] in
            self.model.request(API.Main, FirstModel.self)
                .map{$0.stories ?? []}
                .do(onNext: {
                    self.data = $0
                })
        })

extension Observable {
    func map<T: HandyJSON>(_ type: T.Type) -> Observable<T> {
        return map { response in
            guard let response = response as? Moya.Response else {
                throw RxSwiftMoyaError.ResponseError
            }
            
            guard (200...209) ~= response.statusCode else {
                throw RxSwiftMoyaError.RequestFailedError
            }
            
            guard let json = try? JSONSerialization.jsonObject(with: response.data, options: JSONSerialization.ReadingOptions.init(rawValue: 0)) as! [String: Any] else {
                throw RxSwiftMoyaError.ResponseError
            }
            
            let object = JSONDeserializer<T>.deserializeFrom(dict: json)
            guard let model = object else {
                throw RxSwiftMoyaError.ParseJSONError
            }
            return model
        }
    }
}

列表翻页时，如何追加数据呢？

请教翻页问题：想实现列表翻页功能，但是接口返回的list 如何追加到self.data上呢？如何将追加的最新列表数据显示到列表上呢？

  homeAction = Action<Void, Msg<BaseUser>>.init(workFactory: {[unowned self] in
            
            var params : Dictionary<String, Any> = [:]
            params["lp"]            = self.lp
            params["page"]          = "1"
            params["age_min"]       = "-1"
            params["age_max"]       = "-1"
            params["height_min"]    = "-1"
            params["height_max"]    = "-1"
            params["prov"]          = ""
            params["city"]          = ""
            params["user_id"]       = "1"
            
            
            return self.model.request(UserAPI.homeList(params), Msg<BaseUser>.self)
                    .debug()
                    .filter({ [unowned self] (value) -> Bool in
                        
                        Loger.log(msg: "\(value.code!) \(value.msg!)")
                        if value.code == 1 {
                            self.lp = value.lp ?? ""
                            self.refreshStatus.value = RefreshStatus.DropDownSuccess
                            
                            //处理返回的数据，给dataSource赋值
                            if (value.list?.count)! >= 0 {
                                self.refreshStatus.value = RefreshStatus.PullSuccessHasMoreData
                            } else {
                                self.refreshStatus.value = RefreshStatus.PullSuccessNoMoreData
                            }
                            
                            self.data = value.list ?? []
                            return true
                        }
                        
                        
                        self.refreshStatus.value = RefreshStatus.DropDownSuccess
                        
                        return true
                        
                    })
        })

self.viewModel?
            .homeAction?
            .execute(())
            .filter({ (value) -> Bool in
                
                Loger.log(msg: "\(value.code!) \(value.msg!)")
                if value.code == 1
                {
                    return true
                }
                return false
                
            })
