带有不同数组的多个表视图



我有一个详细观点,显示了活动的细节,参加的人以及要求参加的人。我创建了两个不同类型的数组,但是它们具有相同的字段,只是第一个结构代表用" status_confirm"字段等于1(因此被接受的用户)的用户,而另一个结构为" status_confirm"等于0(等待接受的用户)。我声明了两个数组,第一个数组:var arrayUserAccepted = [User_accepted] ()。第二个:var arrayUserWaiting = [User_waiting] ()。结构图像下一步:我通过PHP脚本填充这些结构

func getData(){
    let url = URL(string: “MYURL”)
    URLSession.shared.dataTask(with:url!, completionHandler: {(data, response, error) in
    guard let data = data, error == nil else { return }
    do {
        let json = try JSONSerialization.jsonObject(with: data, options: []) as! [String:AnyObject]
        print("JSON: n(json)n")
        let waiting = json["waiting"] as! [AnyObject]
        let accepted = json["accepted"] as! [AnyObject]
        DispatchQueue.main.async {
            for list_user_waiting in waiting {
                let id_user_waiting = list_user_waiting["id_user”] as! String
                let name_user_waiting = list_user_waiting[“name_user”] as! String
                let email_user_waiting = list_user_waiting["email"] as! String
                var photo_user_waiting = list_user_waiting[“photo”]
                let status_user_waiting = list_user_waiting["status”] as! String
                if photo_user_waiting is NSNull {
                    photo_user_waiting = ""
                }
                let listUserWaiting = User_waiting(id_user_waiting: id_user_waiting, name_user_waiting: name_user_waiting, email_user_waiting: email_utente_attesa, foto_waiting: photo_user_waiting as! String, status_waiting: status_user_waiting)
                self.arrayUserWaiting.append(listUserWaiting)
                self.tableViewListUserWaiting.reloadData()
            }
            for list_user_accepted in accepted {
                let id_user_accepted = list_user_accepted["id_utente"] as! String
                let name_user_accepted = list_user_accepted["name_utente"] as! String
                let email_user_accepted = list_user_accepted["email"] as! String
                var photo_user_accepted = list_user_accepted[“photo"]
                let status_user_accepted = list_user_accepted["status”] as! String
                if photo_user_accepted is NSNull {
                    photo_user_accepted = ""
                }
                let listUserAccepted = User_accepted(id_user: id_user_accepted, nome_utente: name_user_accepted, email: email_user_accepted, foto: photo_user_accepted as! String, stato: status_user_accepted)
                self.arrayUserAccepted.append(listUserAccepted)
                self.tableViewListUserAccepted.reloadData()
            }
        }
    } catch let error as NSError {
        print(error)
    }
}).resume()}

这是我在ViewDidload()中调用的函数。下一步是使用表视图的功能,在这里我认为有禁令

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    var count: Int?
    if tableView == self.tableViewListUserAccepted {
        count = arrayUserAccepted.count
    }
    if tableView == self.tableViewListUserWaiting {
        count = arrayUserWaiting.count
    }
    return count!
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
    if tableView == self.tableViewListUserAccepted {
        cell.imageProfileUserAccepted.image = UIImage(named: "imageDefault")
        cell.valueSliderUserAccepted.value = Float(50) //JUST FOR POPULATE THE INTERFACE
        cell.name_user_accepted.text = arrayUserAccepted[indexPath.row].name_user
    } 
    if tableView == self.tableViewListUserWaiting {
        cell.imageProfileUserWaiting.image = UIImage(named: "imageDefault")
        cell.valueSliderUserWaiting.value = Float(23) //JUST FOR POPULATE THE INTERFACE
        cell.name_user_waiting.text = arrayUserWaiting[indexPath.row].name_user_waiting
    }
    return cell
}

一旦完成了这一轮,我就启动了该应用程序,但什么都没有。表是空的。在控制台中,脚本正确地回答了我,因此我无法弄清楚该错误在哪里。不用说,我已经在Main.Storyboard和代码中宣布了这两个表的.delegate和.datasource。

一切都很好,只需更改条件的格式,它将起作用。

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    var count: Int?
    if tableView == self.tableViewListUserAccepted {
        count = arrayUserAccepted.count
    } else {
        count = arrayUserWaiting.count
    }
    return count!
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if tableView == self.tableViewListUserAccepted {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
        cell.imageProfileUserAccepted.image = UIImage(named: "imageDefault")
        cell.valueSliderUserAccepted.value = Float(50) //JUST FOR POPULATE THE INTERFACE
        cell.name_user_accepted.text = arrayUserAccepted[indexPath.row].name_user
        return cell
    } else {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
        cell.imageProfileUserWaiting.image = UIImage(named: "imageDefault")
        cell.valueSliderUserWaiting.value = Float(23) //JUST FOR POPULATE THE INTERFACE
        cell.name_user_waiting.text = arrayUserWaiting[indexPath.row].name_user_waiting
        return cell
    }
}

还检查两个tableViewdatasourcedelegate是否设置了。最后在viewDidLoad()方法填充数组后,在两个桌面上调用tableView.reloadTable()方法。
