Question

I would like to know how to create a horizontal scrollview in swift programmatically without using storyboards, with a page controller.

Answer 1

import UIKit
class SecondViewController: UIViewController, UIScrollViewDelegate {
var scrollview = UIScrollView()
var imageview = UIImageView()
var view1 = UIView()
override func viewDidLoad() {
super.viewDidLoad()
imageview.frame = CGRect(x: 0, y: 0, width: view.frame.size.width , height: 1000)
imageview.image = UIImage(named: "image")
scrollview.delegate = self
scrollview.contentSize = CGSize(width: imageview.frame.width, height: imageview.frame.height)
scrollview.backgroundColor = UIColor.red
imageview.backgroundColor = UIColor.green
self.scrollview.addSubview(imageview)
view.addSubview(scrollview)
scrollview.translatesAutoresizingMaskIntoConstraints = false
scrollview.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
scrollview.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
scrollview.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
scrollview.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
// Do any additional setup after loading the view.
}

Answer 2

Try This
import UIKit
class ViewController: UIViewController, UIScrollViewDelegate {
var scrollView: UIScrollView!
let textData: String = "Just to add onto the already great answers, you might want to add multiple labels in your project so doing all of this (setting size, style etc) will be a pain. To solve this, you can create a separate UILabel class."
override func viewDidLoad() {
super.viewDidLoad()
let textLable = UILabel(frame: CGRect(x: 0, y: 0, width: 1000, height: 200))
textLable.text = textData
self.scrollView = UIScrollView()
self.scrollView.delegate = self
self.scrollView.contentSize = CGSize(width: textLable.frame.width, height: textLable.frame.height)
scrollView.addSubview(textLable)
view.addSubview(scrollView)
}
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
scrollView.frame = view.bounds
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
