ios - 将单元格名称传递给 View Controller 旁边

Question

首先，感谢您阅读我的问题!

因此，我遇到了一些有关将单元格名称传递到下一个 View 的问题。现在它会传递它，但只会显示最近加载的单元格。

现在的编程方式如下:

var passName = ""
var passAuthor = ""
var passLikes = 0
var passDescrip = ""

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)!

    // Configure the PFQueryTableView
    self.parseClassName = "Location"
    self.textKey = "Name"
    self.pullToRefreshEnabled = true
    self.paginationEnabled = true
    self.objectsPerPage = 5

}
override func queryForTable() -> PFQuery {
    let query = PFQuery(className: "Location")
    query.orderByAscending("Name")
    return query
}

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

    let cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! CustomPFTableViewCell!

    print("Loading Parse Database Files...")
    // Extract values from the PFObject to display in the table cell
    if let name = object?["Name"] as? String {
        cell?.nameTextLabel?.text = name
        passName = name
        print("Loading " + name)
    }
    if let author = object?["authorName"] as? String {
        cell?.authorTextLabel?.text = author
        passAuthor = author
    }
    if let likes = object?["Likes"] as? Int {
        let stringVal = String(likes)
        cell?.numLikes.text = stringVal
        passLikes = likes
    }
    if let descrip = object?["Description"] as? String {
        passDescrip = descrip

    }
    let initialThumbnail = UIImage(named: "Unloaded")
    cell.customFlag.image = initialThumbnail
    if let thumbnail = object?["imageCover"] as? PFFile {
        cell.customFlag.file = thumbnail
        cell.customFlag.loadInBackground()


    }
    print("Finished loading!")


    return cell
}

//Original prepareForSegue
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if (segue.identifier == "toDetailScene") {

        // initialize new view controller and cast it as your view controller
        let viewController = segue.destinationViewController as! DetailViewController




        viewController.tripName = passName
        viewController.tripAuthor = passAuthor
        viewController.tripLikes = passLikes
        viewController.tripDescrip = passDescrip
    }
}

稍后，下一个 View Controller 使用以下简单代码接收它: @IBOutlet 弱变量名称:UILabel! @IBOutlet 弱变量喜欢:UILabel! @IBOutlet 弱变量作者:UILabel! @IBOutlet 弱变量描述:UITextView!

var currentObject : PFObject?

var tripName = ""
var tripAuthor = ""
var tripLikes = 0
var tripDescrip = ""

override func viewDidLoad() {
    super.viewDidLoad()



    //Hookup
    name.text = tripName
    likes.text = String(tripLikes)
    author.text = tripAuthor
    descrip.text = tripDescrip

}

我需要修复它，这样它就不会一直尴尬地显示错误的文章/信息。

如果我可以简单地拉出他们单击的正确单元格，那么我可以从每个标签中拉出文本吗？那么我怎样才能获得正确的细胞呢？

顺便说一句:它通过 show segue 从单元格转移到下一个 View Controller 。 (在导航 Controller 中)

非常感谢!

@Paulw11 在评论中回答了这个问题，它解决了我的问题。

发件人:AnyObject？允许我添加:

let cell = sender as! CustomPFTableViewCell

然后我所要做的就是更新方法以直接从单元格连接文本字段的新值。

这是代码:

let viewController = segue.destinationViewController as! DetailViewController         
let cell = sender as! CustomPFTableViewCell

        viewController.tripName = cell.nameTextLabel.text!
        viewController.tripAuthor = cell.authorTextLabel.text!
        viewController.tripLikes = Int(cell.numLikes.text!)!
