无法将自定义单元格值传递给 swift 中的新 viewController

Question

我有一个使用自定义单元格的表格视图。问题是我不知道如何使用 prepareForSegue 将自定义单元格中的 textField 值传递到下一个视图控制器。我使用的代码是：

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject) -> PFTableViewCell {

    var cell = tableView.dequeueReusableCellWithIdentifier("StaffCell") as StaffCustomCell!
    if cell == nil {
        cell = StaffCustomCell(style: UITableViewCellStyle.Default, reuseIdentifier: "StaffCell")
    }

    // Extract values from the PFObject to display in the table cell
    cell?.staffNic?.text = object["Nic"] as String!
    cell?.staffApellido?.text = object["Apellido"] as String!

    var initialThumbnail = UIImage(named: "iboAzul")
    cell.staffFoto.image = initialThumbnail
    if let thumbnail = object["FotoStaff"] as? PFFile {
        cell.staffFoto.file = thumbnail
        cell.staffFoto.loadInBackground()
    }

    return cell
}


// Pass the custom cell value to the next view controller
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

    if segue.identifier == "segueStaffSeleccionado" {
        let detailViewController = segue.destinationViewController.visibleViewController as StaffDetailViewController

        // This is the code I have no idea how to write. I need to get a value from the selected customCell


    }

有什么想法吗？非常感谢

您通过 tableView.indexPathForSelectedRow 获取选定的单元格。使用该 indexPath，您可以访问单元格：

// Pass the custom cell value to the next view controller 
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

    if segue.identifier == "segueStaffSeleccionado" {
        let detailViewController = segue.destinationViewController.visibleViewController as StaffDetailViewController

    if let indexPath = self.tableView.indexPathForSelectedRow() {
        let cell = self.tableView.cellForRowAtIndexPath(indexPath)

        // path the cell's content to your detailViewController
        detailViewController.myProperty = cell.textLabel?.text
    }
}

另一种解决方案：如果直接从 tableViewCell 执行转场（通过按住 Ctrl 并从 InterfaceBuilder 中的单元格拖动转场），那么 sender 是单元格：

// Pass the custom cell value to the next view controller
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    ...

    if let cell = sender as StaffCustomCell {
        // path the cell's content to your detailViewController
        detailViewController.myProperty = cell.textLabel?.text
    }
}
