Make keyboard disappear when clicking outside of Search Bar - SWIFT

问题

I have a UIViewController and I have embedded a Search Bar and a Collection View. When I press on the searchbar, the keyboard appears. I would like to hide this keyboard if the user decides to change his mind by tapping any where on the screen but the search bar. I have tried the following without success:

Adding a Tap Gesture Recognizer

using 'self.mySearchBar.endEditing(true)'

class CollectionViewFolder: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate ,UICollectionViewDelegateFlowLayout, UISearchBarDelegate{

/*** OUTLETS ***/
@IBOutlet weak var mySearchBar: UISearchBar!


// 1. I have tried adding a Tap Gesture Recognizer
// TAP ON SCREEN LISTENER
@IBAction func tapOnScreen(_ sender: UITapGestureRecognizer) {
   print("tap tap ...")
   self.mySearchBar.resignFirstResponder()
}



// 2.  Added the following to the viewDidLoad:
override func viewDidLoad() {
   super.viewDidLoad()

   self.mySearchBar.endEditing(true)
 }

}

You can use this extension.

extension UIViewController {
    func hideKeyboardWhenTappedAround() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard))
        tap.cancelsTouchesInView = false
        view.addGestureRecognizer(tap)
    }

    @objc func dismissKeyboard() {
        view.endEditing(true)
    }
}

Usage. In your viewController:

override func viewDidLoad() {
    super.viewDidLoad()

    hideKeyboardWhenTappedAround()
}
