prepareForSegue（swift 3）

Question

之后文本没有完全传递所以我构建了一个应用程序，它将消息加载到tableView单元格中。 现在我希望用户能够打开个别文章。 为了做到这一点，我使用prepareForSegue方法传递了选定的单元格，它可以工作，但部分工作。 它正确地传递了标题和图像，但部分显示了全文，准确地说它显示在单元格中。

这里是我的新闻类的表：

import Alamofire //Framework for handling http requests 
    import UIKit 
    import AlamofireImage 


    class NewsTableViewController: UITableViewController { 

//Custom struct for the data 
struct News { 
    let title : String 
    let text : String 
    let link : String 
    let imgUrl : String 

    init(dictionary: [String:String]) { 
     self.title = dictionary["title"] ?? "" 
     self.text = dictionary["text"] ?? "" 
     self.link = dictionary["link"] ?? "" 
     self.imgUrl = dictionary["imgUri"] ?? "" 
    } 
} 

//Array which holds the news 
var newsData = [News]() 

// Download the news 
func downloadData() { 
    Alamofire.request("https://api.sis.kemoke.net/news").responseJSON { response in 
     print(response.request as Any) // original URL request 
     print(response.response as Any) // HTTP URL response 
     print(response.data as Any)  // server data 
     print(response.result) // result of response serialization 

     //Optional binding to handle exceptions 
     self.newsData.removeAll() // clean the data source array 
     if let json = response.result.value as? [[String:String]] { 
      for news in json { 
       self.newsData.append(News(dictionary: news)) 
      } 
      self.tableView.reloadData() 
     } 
    } 
} 

override func viewDidLoad() { 
    super.viewDidLoad() 
    downloadData() 
    tableView.rowHeight = 100 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
} 

override func numberOfSections(in tableView: UITableView) -> Int { 
    return 1 
} 

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

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as? newsCellTableViewCell 
    let news = newsData[indexPath.row] 
    cell?.headline.text = news.title 

    Alamofire.request(news.imgUrl).responseImage { response in 
     debugPrint(response) 
     print(response.request as Any) 
     print(response.response as Any) 
     debugPrint(response.result) 
     let cellImage = response.result.value 
     if let image = response.result.value { 
      print("image downloaded: \(image)") 
     } 
     cell?.thumbnailImage.image = cellImage 
    } 
    print(news.imgUrl) 
    return cell! 
    } 


     // MARK: - Navigation 

override func prepare(for segue: UIStoryboardSegue, sender: Any?) { 
    if segue.identifier == "showArticle" { 
     let nextScene = segue.destination as! ArticleViewController 
     // Pass the selected object to the new view controller. 
     if let indexPath = self.tableView.indexPathForSelectedRow { 
      let selectedCells = newsData[indexPath.row] 
      nextScene.articleTitleString = selectedCells.title 
      nextScene.receiveFullText = selectedCells.title 

      //Downloading an image to be displayed in a single article 
      Alamofire.request(selectedCells.imgUrl).responseImage { response in 
       debugPrint(response) 
       print(response.request as Any) 
       print(response.response as Any) 
       debugPrint(response.result) 
       let cellImage = response.result.value 
       nextScene.articleImage.image = cellImage! 
      } 
     } 
    } 
} 
} 

，这里是我的单篇文章的目的地视图控制器中，我传递的信息

class ArticleViewController: UIViewController { 

@IBOutlet weak var articleTitle: UILabel! 
var articleTitleString = "" 
@IBOutlet weak var articleImage: UIImageView! 
@IBOutlet weak var fullText: UITextView! 
var receiveFullText = "" 

override func viewWillAppear(_ animated: Bool) { 
    articleTitle.text = articleTitleString 
    fullText.text = receiveFullText 
} 
} 

这是什么情况

请参阅？即使服务器正在返回全文，也不会显示全文。 我做了测试，通过在另一个视图控制器中创建一个textView并从服务器获取文本，它工作正常。

问题看起来像它的复制单元格中的标签的布局和显示的是在该标签。 也尝试将另一个标签放入单元格以加载文本init，并且它正常工作，比单击单元格后显示的是该标签中的内容。

我想要的是在发生这种情况时加载全文。

Answer 1

nextScene.articleTitleString = selectedCells.title 
nextScene.receiveFullText = selectedCells.title 

你两次传递，而不是全文标题...
