Swift - UITableView inside UIViewController, UITableView functions are not called - ios

Question

I inserted a tableview inside a UIViewController. But my code is not working. When I checked I found that none of the tableview functions are not called.
class CustomViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var authorArticlesTableView: UITableView!
var authorid: Int!
var authorname: String!
var articles: [JSON]? = []
func loadArticles(){
let url = "http:here.com/" + String(authorid) + "/"
println(url)
Alamofire.request(.GET, url).responseJSON { (Request, response, json, error) -> Void in
if (json != nil){
var jsonObj = JSON(json!)
if let data = jsonObj["articles"].arrayValue as [JSON]?{
self.articles = data
self.authorArticlesTableView.reloadData()
}
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
self.loadArticles()
println("viewDidLoad")
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
println("numberOfRowsInSection")
return self.articles?.count ?? 0
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("CustomCell") as! CustomTableViewCell
cell.articles = self.articles?[indexPath.row]
println("cellForRowAtIndexPath")
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
performSegueWithIdentifier("WebSegue", sender: indexPath)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
}
Any solution for this?
Thanks,

Answer 1

You have to set your view controller as a table view delegate/datasource:
add to the end of the viewDidLoad:
authorArticlesTableView.delegate = self
authorArticlesTableView.dataSource = self

Answer 2

Set table delegate and dataSource :
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}

Answer 3

Sometimes, if you forget to drap and drop UITableViewCell to UITableView. XCode don't understand TableView has Cell.
By default, when you drap and drop UITableView into UIViewController. I see UITableView has Cell. But you need to drap and drop UITableViewCell into UITableView also.
It is work with me.

Answer 4

Makes sense to do it in your
#IBOutlet weak var authorArticlesTableView: UITableView!
so it will become
#IBOutlet weak var authorArticlesTableView: UITableView! {
didSet {
authorArticlesTableView.delegate = self;
authorArticlesTableView.dataSource = self;
}
}
