Swift Question

Cell from Xib with Swift 3

I already read and saw some videos about this subject but i can't get this to work. Im trying to a cell from a xib instead of the storyboard.

This is my ViewController (where i have the Table View).

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

@IBOutlet var tableView: UITableView!


override func viewDidLoad() {
super.viewDidLoad()

// Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

return 5
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! CellTableView

cell.test.text = "A";

return cell;

}

}


This is my CellTableView (the class where i have my Cell):

import UIKit

class CellTableView: UITableViewCell {

override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}

@IBOutlet var teste: UILabel!

override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)

// Configure the view for the selected state
}

}


I always used the Table View Cell inside the Table View on the StoryBoard but i want to try a XIB approach now.

I added the cell Identifier on the cell XIB to call it with the dequeueReusableCell method.

What i could be doing wrong? I tried to Outlet the dataSource and the delegate of the Table View but i got an error (and i think its not the right steps).

Answer

You need to register your nib object.

In viewDidLoad():

let nib = UINib(nibName: "nameOfYourNibFile", bundle: nil)

tableView.register(nib, forCellReuseIdentifier: "yourIdentifier")

You also need to return the number of sections:

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