Question

I\'m trying to recognize left/right swipe gesture in a UIScrollView. I\'ve tried to create UISwipeGestureRecognizers and associate them with the sc

Answer 1

For those who want to animate and customize their swipe gesture recognizers.

We can use UIScrollView and UIGestureRecognizer delegates:

 Class ViewController: UIViewController, UISCrollViewDelegate, UIGestureRecognizerDelegate { 


   override func viewDidLoad() {
    super.viewDidLoad()

    scrollView.delegate = self
    swipeLeft.delegate = self
    swipeRight.delegate = self

  }


  func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
    return true
  }

  func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
    return true
  }

  func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
    return scrollView.alwaysBounceHorizontal
  }


  func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer) {

    // Your custom animation at the end of scrolling.
  }
}
