import UIKit
class ViewController: UIViewController {
@IBOutlet weak var movieImageView: UIImageView!
    @IBOutlet weak var titleLabel: UILabel!
    @IBOutlet weak var pageControl: UIPageControl!
    @IBOutlet weak var segmentedControl: UISegmentedControl!
    
    let movies = ["spiderMan01", "spiderMan02", "spiderMan03"]
    let movieTitle = ["Home Coming", "Far From Home", "No Way Home"]
    var index = 0
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        
        
    }
func movieChange () {
        movieImageView.image = UIImage(named: movies[index])
        titleLabel.text = movieTitle[index]
        pageControl.currentPage = index
        segmentedControl.selectedSegmentIndex = index
        
    }
    
    @IBAction func pre(_ sender: Any) {
        index = (index + movies.count - 1 ) % movies.count
        movieChange()
    }
    
    @IBAction func next(_ sender: Any) {
        index = (index + 1) % movies.count
       movieChange()
        
    }
    
    @IBAction func moviePageControl(_ sender: UIPageControl) {
        index = (index + 1) % movies.count
        movieChange()
    }
    
    @IBAction func movieSegmentedControl(_ sender: UISegmentedControl) {
        index = segmentedControl.selectedSegmentIndex
        movieChange()
    }
    
    @IBAction func swipeLeft(_ sender: UISwipeGestureRecognizer) {
        index = (index + movies.count - 1) % movies.count
        movieChange()
    }
    
    
    @IBAction func swipeRight(_ sender: UISwipeGestureRecognizer) {
        index = (index + 1) % movies.count
        movieChange()
    }
