如何将UITableView数据(UIImage和字符串)提取到另一个ViewController

我想将TableView中包含的存储数据传递给另一个ViewController。我的customCell有一个UIImage和一个字符串。 当用户按下单元格时,我想显示一个带有UIImage的“detail view controller”,以及一个包含所选单元格信息的标签。

这是我的代码:

import UIKit


class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

@IBOutlet weak var dataTableView: UITableView!

var myList = [dataList]()

var textToBeSent: String = ""

var selectedImage: UIImage?
var selectedLabel: String?

//Load Items To List

func loaditems(){
    let item1 = dataList(photoList: UIImage.self(), itemDescription: "Descripcion Aqui")
    let item2 = dataList(photoList: UIImage.self(), itemDescription: "Aqui tmb")

    myList += [item1,item2]
}

//var list = ["Documento 1", "Documento 2", "Documento 3"]

override func viewDidLoad() {
    super.viewDidLoad()

    if let savedData = loadSavedItems(){
        myList += savedData
    } else {

    loaditems()
    }


    //dataTableView.register(UITableViewCell.self, forCellReuseIdentifier: "reusablecell")


    // Do any additional setup after loading the view, typically from a nib.
}

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

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "prototype", for: indexPath) as! PrototypeCell

    let itemsinCell = myList[indexPath.row]

    cell.imageItem.image = itemsinCell.photoList
    cell.itemDescription.text = String(itemsinCell.itemDescription)

    return cell
}

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == .delete{
        myList.remove(at: indexPath.row)
        dataTableView.reloadData()
    }

    saveToSavedData()
}

这是我想传递某个单元格数据的函数。 数据来自使用aDecoder NSCoder存储在“数据列表”中的Swift文件。

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {


    print("Row \(indexPath.row) selected")
    selectedImage! = myList[indexPath.row].photoList
    selectedLabel! = myList[indexPath.row].itemdescription
    performSegue(withIdentifier: "selectedRowSegue", sender: myList[indexPath.row])
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if(segue.identifier == "selectedRowSegue"){
        let chosenRowViewController = segue.destination as! chosenRowViewController
        chosenRowViewController.image3 = selectedImage?.photoList
        chosenRowViewController.label3 = selectedLabel?.itemDescription
    }
}

展开一段,以便用上一段的数据填充单元格 视图控制器:

//Unwinde Segue
@IBAction func unWindlToList(sender: UIStoryboardSegue){
    if let sourceViewController = sender.source as? ProcessViewController, let item = sourceViewController.item{
        let newIndexPath = IndexPath(row: myList.count, section: 0)
        myList.append(item)
        dataTableView.insertRows(at: [newIndexPath], with: .automatic)
    }
    saveToSavedData()
}
//Archive Data
func saveToSavedData(){
    NSKeyedArchiver.archiveRootObject(myList, toFile: (dataList.fileFolder?.path)!)
}
//Unarchive Data
func loadSavedItems() -> [dataList]?{
    return NSKeyedUnarchiver.unarchiveObject(withFile: (dataList.fileFolder?.path)!) as? [dataList]
}

}

class PrototypeCell: UITableViewCell {

    @IBOutlet weak var itemDescription: UILabel!

    @IBOutlet weak var imageItem: UIImageView!

}
