So I built an app which loads the news into the tableView cells. Now I want the user to be able to open individual article. To do that I passed the selected cells using prepareForSegue method and it works but partially. It passes the title and image properly but the full text is shown partially, to be precise it is shown as in the cells.
Here is my table of news class:
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!
}
}
}
}
}
And here is my destination view controller for the single article in which I am passing the information
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
}
}
And this is what happens

See? The full text is not shown even though the server is returning full text. I did test this by creating a textView in another view controller and get the text from the server and it worked fine.
The issue looks like it's copying a layout of the label in the cell and displaying what is in that label. Also a tried putting another label in to the cell to load the text init and it worked properly, than after tapping a cell it displayed what was in that label.
What I want is to load a full text when this segue happens.
