arrays - 如何在表格视图单元格中按字母顺序对 JSON 数据进行排序

问题描述

我从服务器以 JSON 格式获取用户数据。现在我可以获取用户详细信息，但它会自动按日期排序。以下是从服务器获取用户详细信息的代码：

func getAllDoctor(){

    let param = ["page":"1"]
    print(param,"param123")
    Alamofire.request(helper.MainURL + "patient/getAllDoctor", method:.post,parameters: param).responseJSON { response in

        self.stopAnimating()

        if let result = response.result.value {
            print(1)
            let DictResponse = JSON(result as! NSDictionary)

            if DictResponse["success"].boolValue
            {
                self.marrDoctorList = DictResponse["data"].arrayValue                    
                self.tblDoctors.reloadData()
            }

        }

        }.responseString { (strREsopns) in
            print(strREsopns)
    }

}

这是表格视图功能：

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return  UITableView.automaticDimension
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return marrDoctorList.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! AllDoctorsTVC

    cell.selectionStyle = .none
    cell.viewBG.layer.cornerRadius = 5
    cell.viewBG.layer.borderWidth = 1
    cell.viewBG.layer.borderColor = UIColor.lightGray.cgColor

    cell.lblName.text = self.marrDoctorList[indexPath.row]["name"].stringValue
    cell.lbl1.text = self.marrDoctorList[indexPath.row]["categories_name"].stringValue

    cell.imgDoctor.sd_setImage(with: URL(string: marrDoctorList[indexPath.row]["profile_image"].stringValue), placeholderImage: UIImage(named: ""))
    cell.imgDoctor.layer.cornerRadius = cell.imgDoctor.frame.height / 2
    cell.imgDoctor.clipsToBounds = true

    cell.imgRead.isHidden = true

    return cell
}

我想按用户名的字母顺序对它们进行排序。

重新加载 tableView（作为 JSON 对象）时的数据结构本质上是：

{"success":true,"data":[
{"doctor_id":"149","name":"Ferit Dadasli","description":"Ortodontist","expertise_categories":"2","categories_name":"Di\u015f Hekimi","profile_image":"http:\/\/www.....net\/app\/assets\/default\/user1.png"},
{"doctor_id":"141","name":"Ahmet Karaman","description":"Pedodontist","expertise_categories":"1","categories_name":"Doktor","profile_image":"http:\/\/www.....net\/app\/assets\/default\/user1.png"},
...

解决方案

您可以尝试使用如下排序函数对“self.marrDoctorList”进行排序：

self.marrDoctorList.sorted { $0. name.lowercased() < $1.name.lowercased() }

例如在您的代码中

        if DictResponse["success"].boolValue
        {
            self.marrDoctorList = DictResponse["data"].arrayValue.sorted { $0. name.lowercased() < $1.name.lowercased() }    

//or
    self.marrDoctorList.sorted { $0. name.lowercased() < $1.name.lowercased() } 

            self.tblDoctors.reloadData()
        }
