Create UITableView programmatically in Swift

Question

I try to implement UITableView programmatically without use of xib or Storyboards. This is my code:

ViewController.swift

import UIKi         


        

Answer 1

It makes no sense that you are using a UITableViewController as the data source and delegate for your view controller's table view. Your own view controller should be the table view's data source and delegate.

Since you seem to want a view controller with a table view that doesn't take up the entire view, move every thing to your view controller as follows:

ViewController.swift:

import UIKit

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        let tableView: UITableView = UITableView()
        tableView.frame = CGRect(x: 10, y: 10, width: 100, height: 500)
        tableView.dataSource = self
        tableView.delegate = self

        self.view.addSubview(tableView)
    }

    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        NSLog("sections")
        return 2
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        NSLog("rows")
        return 3
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        NSLog("get cell")
        let cell = UITableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: "Cell")
        cell.textLabel!.text = "foo"
        return cell
    }  
}
