我想将表格单元格数据(xib文件)传递给表格视图(也是一个xib文件).我尝试使用以下代码传递数据,但没有得到适当的结果.

PropertyCell.swift

import UIKit

    class PropertyCell: UITableViewCell {

    @IBOutlet weak var propertyCodeLbl: UILabel!
    @IBOutlet weak var addressLbl: UILabel!

    }

我在下面附上了PropertyCell的截图 –

PropertyTableVC.swift

import UIKit
import Alamofire

class PropertyTableVC: UITableViewController {


    @IBOutlet var propertyTabel: UITableView!

    let URL_Landlord_Property_List = "http://127.0.0.1/source/api/LandlordPropertyList.php"
    var count: Int = 0
    var landlordPropertyArray: [PropertyList]? = []

    override func viewDidLoad() {
        super.viewDidLoad()
        fetchData()
        propertyTabel.dataSource = self
        propertyTabel.delegate = self

        let nibName = UINib(nibName: "PropertyCell",bundle:nil)
        self.propertyTabel.register(nibName,forCellReuseIdentifier: "Cell")
    }

    func fetchData(){
        let urlRequest = URLRequest(url: URL(string: URL_Landlord_Property_List)!)
        let task = URLSession.shared.dataTask(with: urlRequest) { (data,response,error) in
            if error != nil{
                print(error!)
                return
            }
            print(data!)
            self.landlordPropertyArray = [PropertyList]()
            self.count = (self.landlordPropertyArray?.count)!
            do{
                let json = try JSONSerialization.jsonObject(with: data!,options: .mutableContainers) as! [String: AnyObject]

                if let datafromjson = json["landlords_property_list"] as? [[String: AnyObject]] {
                    print(datafromjson)
                    for data in datafromjson{
                        var property = PropertyList()
                        if let id = data["ID"] as? Int,let code = data["Code"] as? String,let address1 = data["Address"] as? String
                        {
                            property.id = id
                            property.code = code
                            property.address1 = address1

                        }
                        self.landlordPropertyArray?.append(property)
                    }
                    print(self.landlordPropertyArray)
                }
                DispatchQueue.main.async {
                    self.propertyTabel.reloadData()
                }
            }catch let error {
                print(error)
            }
        }
        task.resume()
    }

    override func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    override func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
        return (landlordPropertyArray?.count)!
    }

    override func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        // Configure the cell...
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell",for: indexPath) as! PropertyCell
        cell.propertyCodeLbl.text = self.landlordPropertyArray?[indexPath.item].code
        cell.addressLbl.text = self.landlordPropertyArray?[indexPath.item].address1
        return cell
    } 
}

解决方法

你的TableViewCell：

import UIKit

protocol yourProtocolName { //add protocol here
func getDataFromTableViewCellToViewController (sender : self) //* as you need to pass the table view cell,so pass it as self
}

    class PropertyCell: UITableViewCell {

        @IBOutlet weak var propertyCodeLbl: UILabel!
        @IBOutlet weak var addressLbl: UILabel!
        var delegate : yourProtocolName? //set a delegate

        override func awakeFromNib() {
            super.awakeFromNib()
            if delegate != nil {
                delegate.getDataFromTableViewCellToViewController(sender :self) *
        }
    }
}

而你的ViewController：

import UIKit
import Alamofire

class PropertyTableVC: UITableViewController,yourProtocolName { //conform to the protocol you created in tableViewCell


    @IBOutlet var propertyTabel: UITableView!

    let URL_Landlord_Property_List = "http://127.0.0.1/source/api/LandlordPropertyList.php"
    var count: Int = 0
    var landlordPropertyArray: [PropertyList]? = []

    override func viewDidLoad() {
        super.viewDidLoad()
        fetchData()
        propertyTabel.dataSource = self
        propertyTabel.delegate = self

        let nibName = UINib(nibName: "PropertyCell",for: indexPath) as! PropertyCell
        cell.propertyCodeLbl.text = self.landlordPropertyArray?[indexPath.item].code
        cell.addressLbl.text = self.landlordPropertyArray?[indexPath.item].address1
        return cell
    } 

    func getDataFromTableViewCellToViewController(sender :UITableViewCell) {
        //make a callback here
    }
}

(*)标记的字段是更新的代码
