Question

我是Swift编程新手

带有tableview的SearchBar控制器。我希望在表格中显示多个学生，它的工作正常。我可以将搜索栏控制器添加到表格视图并显示特定的学生数据。表格视图单元格包含我希望在搜索后显示特定学生的学生信息和图像

这是代码

@IBOutlet var SearchBarDisp：UISearchBar！

override func viewDidLoad()
 {
        super.viewDidLoad()
        searchController.searchResultsUpdater = self
        searchController.hidesNavigationBarDuringPresentation = false
        searchController.dimsBackgroundDuringPresentation = false
        tableView.tableHeaderView = searchController.searchBar  
   }

func updateSearchResults(for searchController: UISearchController) {
//todo
}

我可以从json获得学生数据

func getKids(url : String) {

        UIApplication.shared.beginIgnoringInteractionEvents()

        var errorCode = "1"

        var msg = "Failed"

        var request = URLRequest(url: URL(string: "getstaffstudents",
                                          relativeTo: URL(string: serverURL+"/rkapi/api/"))!)

        let session = URLSession.shared

        request.httpMethod = "POST"

        let bodyData = "staffId=\(staffId)"

        request.httpBody = bodyData.data(using: String.Encoding.utf8);

        let task = session.dataTask(with:request,completionHandler:{(d,response,error)in

            do{

                if let data = d {

                    if let jsonData = try JSONSerialization.jsonObject(with: data, options: []) as? NSDictionary {

                        errorCode = String(describing: jsonData["errorCode"]!)

                        msg = jsonData["msg"] as! String

                       print("msg values",msg)

                        if errorCode == "0" {

                            if let kid_list = jsonData["students"] as? NSArray {

                                for i in 0 ..< kid_list.count {

                                    if let kid = kid_list[i] as? NSDictionary {

                                         kidHoleData.removeAll()

                                        let imageURL = url+"/images/" + String(describing: kid["photo"]!)

                                        self.kidsData.append(Kids(
                                            studentId: kid["studentId"] as? String,
                                            name:kid["name"] as? String,
                                            classId : kid["classId"] as? String,
                                            standard: ((kid["standard"] as? String)! + " " + (kid["section"] as? String)!),
                                            photo : (imageURL),
                                            school: kid["schoolName"] as? String,
                                            schoolId : "1",
                                            url : url)
                                        )
                                    }


                                }
                                self.loopCount += 1

                                self.do_table_refresh()
                             }

                        } else {
                            self.displayAlert("Kids", message: msg)
                        }

                    } else {

                        self.displayAlert("Kids", message: "Data Not Available. Please try again")

                    }
                }else {

                    self.displayAlert("Kids", message: "Please try again")

                }

            } catch let err as NSError {

                print("JSON Error \(err)")
            }
        })

        task.resume()
    }

表格视图

 func numberOfSections(in tableView: UITableView) -> Int {

        return (kidsData.count == 0) ? 0 : 1
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        return kidsData.count


    }


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

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

        let maskLayer = CAShapeLayer()
        let bounds = cell.bounds

        maskLayer.path = UIBezierPath(roundedRect: CGRect(x: 3, y: 3, width: bounds.width-15, height: bounds.height-15), cornerRadius: 2).cgPath
        cell.layer.mask = maskLayer

        let row = (indexPath as NSIndexPath).row
        if(kidsData.count>0){

            let kid = kidsData\[row\] as Kids
            cell.kidNameLabel.text = kid.name
            cell.classLabel.text = kid.standard
            cell.kidNameLabel.lineBreakMode = .byWordWrapping
            cell.kidNameLabel.numberOfLines = 0
            cell.kidImageView.image = UIImage(named: "profile_pic")
            cell.kidImageView.downloadImageFrom(link: kid.photo!, contentMode: UIViewContentMode.scaleAspectFit)  //set your image from link array.

        }
        return cell

    }

我希望在桌面视图中显示特定的学生（就像我可以搜索学生姓名作为vani它在桌面视图中显示学生vani）请帮助我

将孔数据复制到attendanceInfoDupilicate

 var attendanceInfoDupilicate = [AttendanceInfo]()

在末尾的Json服务调用内部

self.attendanceInfoDupilicate = self.attendanceInfo

更新搜索控制器

    func updateSearchResults(for searchController: UISearchController)
    {



        let searchToSeatch = AttendanceSearchBarController.searchBar.text

        if(searchToSeatch == "")
        {
            self.attendanceInfo = self.attendanceInfoDupilicate

        }
        else{

            self.attendanceInfo.removeAll()

            let AttedanceData = self.attendanceInfoDupilicate

            var kidsArray = [String]()

            for AttendanceInfo in AttedanceData
            {

                kidsArray.append(AttendanceInfo.name)
                if(AttendanceInfo.name.range(of: searchToSeatch!, options: .caseInsensitive) != nil)
                {
                    self.attendanceInfo.append(AttendanceInfo)

                }

            }




        }

        self.TableView.reloadData()


    }
