Swift 如何从自定义单元格转到imageView？

我已经有了一个自定义表视图单元格的数据数组。目前只包括一个imageView和标签

我想使用imageView创建一个单独的视图控制器，将小缩略图显示为大版本。但是，当然，使用我的数据数组，以便在宿主imageView中加载正确的图像

基本上，我想创建一个HostImageView，当我从列表中选择数据数组时，它将加载我的数据数组

我当前的阵列如下所示：

import UIKit

class PictureViewController: UIViewController {

    @IBOutlet weak var tableView: UITableView!
    var pictures: [picture] = []

    override func viewDidLoad() {
        super.viewDidLoad()
        pictures = createArray()

        tableView.rowHeight = 120


        tableView.delegate = self
        tableView.dataSource = self
    }
    func createArray() -> [picture] {

        var tempPictures: [picture] = []

        let picture1 = picture(image: #imageLiteral(resourceName: "Arteries Hand"), title: "Arteries Hand")
        let picture2 = picture(image: #imageLiteral(resourceName: "Arteries Upper Arm"), title: "Arteries Upper Arm")
        let picture3 = picture(image: #imageLiteral(resourceName: "Arteries Shoulder"), title: "Arteries Shoulder")
        let picture4 = picture(image: #imageLiteral(resourceName: "Arteries Upper Limb"), title: "Arteries Upper Limb")

    tempPictures.append(picture1)
    tempPictures.append(picture2)
    tempPictures.append(picture3)
    tempPictures.append(picture4)

        return tempPictures
    }
}


extension PictureViewController: UITableViewDataSource, UITableViewDelegate {



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

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let picture = pictures[indexPath.row]

        let cell = tableView.dequeueReusableCell(withIdentifier: "pictureCell") as! pictureCell

     cell.setPicture(picture: picture)

        return cell
    }


    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        performSegue(withIdentifier: "segue", sender: self)

    }
}

PictureCell：

import UIKit

class pictureCell: UITableViewCell {

    @IBOutlet weak var pictureImageView: UIImageView!
    @IBOutlet weak var pictureTitleLabel: UILabel!

    func setPicture(picture: picture) {
        pictureImageView.image = picture.image
        pictureTitleLabel.text = picture.title
    }

}

上述方法触发以下类方法，您可以使用它来传输数据：

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    guard let segueId = segue.identifier else { return }

    switch segueId {
    case "segue":

        let destinationVC = segue.destination as! YournextVC
        destVC.pictures = self.pictures // This is how you transfer info to the next View Controller 

    default:
        break
    }
}

---

你能展示你在picture cell类中写的东西吗？你的问题不清楚。你的

didSelectRowAt

实现现在是不必要的，因为你所做的只是调用

performSegue

，你可以直接在情节提要中配置它。

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    guard let segueId = segue.identifier else { return }

    switch segueId {
    case "segue":

        let destinationVC = segue.destination as! YournextVC
        destVC.pictures = self.pictures // This is how you transfer info to the next View Controller 

    default:
        break
    }
}
