Your First Core Data App - Core Data - page 5

Replace the implementation of viewDidLoad with the following:
override func viewDidLoad() {
super . viewDidLoad ()
title = "\"The List\""
tableView . registerClass ( UITableViewCell . self ,
forCellReuseIdentifier: "Cell" )
}
This will set a title and register the UITableViewCell class with the table view. You
do this so that when you dequeue a cell, the table view will return a cell of the
correct type.
Still in ViewController.swift , declare that ViewController will conform to the
UITableViewDataSource protocol by editing the class declaration:
//Add UITableViewDataSource to class declaration
class ViewController: UIViewController , UITableViewDataSource {
Immediately, Xcode will complain about ViewController not conforming to the
protocol. Below viewDidLoad , implement the following data source methods to fix
the error:
// MARK: UITableViewDataSource
func tableView(tableView: UITableView ,
numberOfRowsInSection section: Int ) -> Int {
return names . count
}
func tableView(tableView: UITableView ,
cellForRowAtIndexPath
indexPath: NSIndexPath ) -> UITableViewCell {
let cell =
tableView. dequeueReusableCellWithIdentifier ( "Cell" )
as UITableViewCell
cell. textLabel !. text = names [indexPath. row ]
return cell
}
If you've ever worked with UITableView , this code should look very familiar. The
first method says that the table view will have as many rows as the names array has
strings.
