Why can't my Table View Cell be shown? - ios

Question

I was learning storyboards tutorial, which is mainly about the use of Tab Bar Controller,Navigation Controller,and Table View Controller. The Table View Controller is embedded in the Navigation Controller.
However, when I ran this app,the Table View Cell can not be seen.I've double checked my code,but still couldn't find the reason.Here are two mages of storyboard.
Document Outline,click here.
View Controller Scene, here.
Code in ViewController.swift is here.
import UIKit
import Foundation
struct Player
{
var name:String?
var game:String?
var rating:Int
init(name:String?, game:String?,rating:Int)
{
self.name = name
self.game = game
self.rating = rating
}
}
let playersData = [
Player(name: "Bill Evans", game: "TTT", rating: 4),
Player(name: "OD", game: "Spin the Bottle", rating: 5),
Player(name: "DB", game: "Texas Holder", rating: 2)]
class PlayersViewController: UITableViewController {
var players:[Player] = playersData
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return players.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
//This method will check to see if there is an existing cell that can be recycled.If not, it will automatically allocate a prototype cell and return it to you.
let cell = tableView.dequeueReusableCellWithIdentifier("PlayerCell", forIndexPath: indexPath)
let player = players[indexPath.row]as Player
cell.textLabel?.text = player.name
cell.detailTextLabel?.text = player.game
return cell
}
}

Answer 1

In your screenshot ("Document Outline"), there is PlayersViewController Scene.
But this should be Players View Controller (with spaces).
This means that you set PlayersViewController as title of ViewController.
You should set this as custom class for this scene (ViewController).
So your scene is handled by UITableViewController which has no data to present, at the moment.
To fix this, select your view controller or scene, go to Identity Inspector and set PlayersViewController in Class property.

Answer 2

//register your cell(nib) in viewdidload
let customCellNib: UINib = UINib(nibName:#"nibName", bundle: nil)
yourTableView.registerNib(customCellNib, forCellReuseIdentifier:#"PlayerCell")
