Tableview - Swift

  • adding table view to the storyboard.

setup table view DataSource and Delegate

  • table view has two weak objects
    • DataSource - object is responsible for providing cells and their data for a table view
    • Delegate - It handles selection, deletion, header/footer, and other related actions.
    override func viewDidLoad() {
        tableView.delegate = self
        tableView.dataSource = self

- next we need to confirm our delgate and dataSource with our view Controller. This is because the delegate and dataSource objects allow assigning a class that must conform to their protocols.

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource

- adding required method stubs 

> A method stub or simply stub in software development is a piece of code used to stand in for some other programming functionality.

- there are two method stubs that added by Xcode.
	- first number of row in section 
	- cell for row at 

1. First number of row in section return as Int

responsible for drawing the number of cells returned by this method.

``` swift
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        //TODO: Return items count
        return 0

  1. other method is cell for row at

returns an object of UITableViewCell type. This is where we can create a cell and pass data to it to configure its UI.

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        //TODO: Return cell
        return UITableViewCell()
  • we use count of the array as the return object of the first method stub.
return array.count
