从 UITableView 推送数据以编程方式查看控制器

Question

我正在尝试将数据从 tableView 推送到 View 控制器。我可以成功地把一些数据传输过来，但我仍然遗漏了一些关键点。我会尽力说明我的问题。在我的 notificationTableView 中，我存储了 userName、userImage、jobName 和 jobImage 等数据。我可以成功推送用户图像和名称，但是 jobName 和 JobImage 无法传输，如下图所示。

在此图像中，我们可以看到具有 userName、userImage、jobName 和 jobImage 的 tableView 部分。

在第二张图中，我们可以看到usersName和Image推送成功。但是，不会传输 jobImage 和名称。

我用来推送信息的代码是

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

    let notification = notifications[indexPath.row]
    if notification.notificationType != .swipe {

        let acceptWorker = jobProgressViewController()
        acceptWorker.workerUser = myUser
        acceptWorker.workerUser = notification.user
        jobProgressView?.myParentViewController = self
        let navController = UINavigationController(rootViewController: acceptWorker)
                  present(navController, animated: true, completion: nil)

    } else {
   print("something else should go here")
}

下面是我用来检索信息的代码。这是我的 jobProgressViewController

     var notification: userNotifications?
     var workerUser: User? {

didSet {
    let name = workerUser?.name
    workerNameLabel.text = name


    guard let profileImage = workerUser?.profileImageUrl else { return }
    workerImageView.loadImageUsingCacheWithUrlString(profileImage)

    if let post = notification?.poster {
        jobImageView.loadImageUsingCacheWithUrlString(post.imageUrl1!)
        jobLabel.text = post.category
        addressLabel.text = post.category
                      }

}
}

   fileprivate func setupView(){
    let postUser = workerUser.self
    let uid = Auth.auth().currentUser?.uid
    let userName = postUser?.name
    let posterId = postUser?.uid
    let post = notification?.poster

    guard let userImage = workerUser?.profileImageUrl else { return }
    Database.database().reference().child("users").child(uid!).observeSingleEvent(of: .value, with: { (snapshot) in
        guard let dictionary = snapshot.value as? [String : Any] else { return }
        let user = User(dictionary: dictionary as [String : AnyObject])

        let currentUser = MyUser(dictionary: dictionary as [String : AnyObject])
        self.posterImageView.image = #imageLiteral(resourceName: "user")
        self.posterImageView.loadImageUsingCacheWithUrlString(userImage)

        self.userNameLabel.text = userName
        self.userNameLabel.font = UIFont.systemFont(ofSize: 30)
        self.userNameLabel.textColor = UIColor.black

        self.workerImageView.image = #imageLiteral(resourceName: "user")
        self.workerImageView.loadImageUsingCacheWithUrlString(currentUser.profileImageUrl!)

        self.workerNameLabel.text = currentUser.name
        self.workerNameLabel.font = UIFont.systemFont(ofSize: 30)
        self.workerNameLabel.textColor = UIColor.black


        self.addressLabel.text = postUser?.address
        self.addressLabel.font = UIFont.systemFont(ofSize: 30)
        self.addressLabel.textColor = UIColor.black

        self.jobLabel.text = post?.category
        self.jobLabel.font = UIFont.systemFont(ofSize: 30)
        self.jobLabel.textColor = UIColor.black



    }, withCancel: { (err) in
        print("attempting to load information")

    })
     print("this is your uid \(posterId!)")
}

下面是我如何填充我的 notificationCell，它在我的 tableView 中显示用户信息

    var jobProgressView: jobProgressViewController? = nil

 var delegate: NotificationCellDelegate?

var notification: userNotifications? {
    didSet {


       guard let user = notification?.user else { return }
       guard let profileImageUrl = user.profileImageUrl else { return }


        profileImageView.loadImageUsingCacheWithUrlString(profileImageUrl)
        configureNotificationLabel()
        configureNotificationType()

        if let post = notification?.poster {
            postImageView.loadImageUsingCacheWithUrlString(post.imageUrl1!)
        }
    }
}

    func configureNotificationLabel() {
    guard let notification = self.notification else { return }
    guard let user = notification.user else { return }
    guard let poster = notification.poster else { return }
    guard let username = user.name else { return }
    guard let notificationDate =  configureNotificationTimeStamp() else { return }
    guard let jobName = poster.category else { return }

    let notificationMessage = notification.notificationType.description

    let attributedText = NSMutableAttributedString(string: username, attributes: [NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: 14)])

    attributedText.append(NSAttributedString(string: notificationMessage , attributes: [NSAttributedString.Key.font: UIFont.systemFont(ofSize: 14), NSAttributedString.Key.foregroundColor: UIColor.black]))

    attributedText.append(NSAttributedString(string: jobName, attributes: [NSAttributedString.Key.font: UIFont.systemFont(ofSize: 14), NSAttributedString.Key.foregroundColor: UIColor.black]))

    attributedText.append(NSAttributedString(string: " \(notificationDate).", attributes: [NSAttributedString.Key.font: UIFont.systemFont(ofSize: 14), NSAttributedString.Key.foregroundColor: UIColor.gray]))
        notificationLabel.attributedText = attributedText
}

如果我遗漏了任何有助于获得答案的信息，请告诉我。谢谢，麻烦您了。

作为讨论，您忘记为 jobProgressViewController

设置通知

在函数 didSelectRowAt indexPath 中添加以下代码：

acceptWorker.notification = notification

从 UITableView 推送数据以编程方式查看控制器

push data from UITableView to view controller programmatically

ios

xcode

uitableview

push

pushviewcontroller
