How to create UITableView in iOS storyboard

To populate a list of items in the iPhone you can use UITableView which provides vertical scrolling over the items. In this article we will UITableView in iOS with storyboard and add some items to it.

Let’s Code

Step 1: Create New Xcode Project & jump towards Main.StoryBoard

Step 2: Click on + icon(Object Library) & Drag UITableView to StoryBoard

Step 3: Add leading, trailing top bottom constraints to the tableView, deselect the Constraint to margin Option.

Step 4:  Create a IBOutlet of UITableView. By clicking right click on UITableView & drag the line to ViewController.swift file

Step 5: To link Data/Array to the UItableView we have Make dataSource conformance to self Means The current ViewController class will adopt the methods of UITableViewDataSouce & we can provide data objects to the UITableView

– numberOfRowsInSection used for how many rows to present in UITableView 

–cellForRowAt used for designing the cell items 

Step 6: To listen click events of UITableView we have Make delegate conformance to self

The Complete Code is here –

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var customTableView: UITableView!
    
    var programmingLanguagesArray = ["Swift", "Objective C", "Java", "Pyton", "C", "C++", "Visual Basic", "PHP", "SQL", "R", "Groovy", "Assembly language", "Pascal", "Basic", "Lisp", "COBOL"]
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setUpUItableView()
    }

    // Setting UItableview 
    func setUpUItableView() {
        customTableView.dataSource = self
        customTableView.delegate = self
        customTableView.estimatedRowHeight = 80// To make resizable cells
        customTableView.rowHeight = UITableView.automaticDimension
        //To register Fresh cell to the TableView
        customTableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
    }

}

// MARK: UITableViewDataSource
extension ViewController: UITableViewDataSource {
    
    // Return a list of item in array
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return programmingLanguagesArray.count
    }
    
    // return a cell for specific row
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        guard let cell = tableView.dequeueReusableCell(withIdentifier: "cell") else {
            return UITableViewCell()
        }
        var content = cell.defaultContentConfiguration()
        content.text = programmingLanguagesArray[indexPath.row]
        cell.contentConfiguration = content
        return cell
    }
}

// MARK: UITableViewDelegate
extension ViewController: UITableViewDelegate {
    
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("Clicked on row -->", indexPath.row)
    }
}
