How to make keyboard dismiss when I press out of searchbar on Swift?

I try to make my searchbar on swift, but I have a problem to dismiss keyboard on screen when I pressed out of searchbar. When I try with textfield, it works perfectly fine with this code.

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
        self.view.endEditing(true)
    }   

It work when i press out of my textfield and then the keyboard is gone. I want to make like that with my searchbar, because when I use searchbar and use the same way like textfield, it doesn't work at all. Any reference or code is very useful for me.

try this :

self.mySearchController.searchBar.endEditing(true)

replace mySearchController with your created controller name.. If you did not create it programmatically but instead you just dragged a search bar from library then IBoutlet your searchable to your class and reference it as:

self.mySearchBar.endEditing(true)

I found it easier and simplier to use Table View for dismissal. (If you're using table view)

Swift 4:

self.tableView.keyboardDismissMode = .onDrag

Tested and working!

func searchBarSearchButtonClicked(searchBar: UISearchBar) 
{
    searchActive = false;
    self.mySearchBar.endEditing(true)
}

Edit for Swift 4.2

func searchBarSearchButtonClicked(_ searchBar: UISearchBar)
    {
        searchActive = false
        self.searchBar.endEditing(true)
    }

 func searchBarSearchButtonClicked(searchBar: UISearchBar) {
        
        searchActive = false;
        searchProject.resignFirstResponder()
    }

This method will be invoked when user click search button on keyboard.So here we can dismiss keyboard.I think this is the right method.

Firstly, Apple's UISearchBarDelegate is the correct solution to hide keyboard when users click a search button while UISearchBar's instance is the first responder (learn UIResponder). In short, searchBarSearchButtonClicked(_:) is what you need for this task.

func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
    searchBar.resignFirstResponder() // hides the keyboard.
    doThingsForSearching()
}

If it doesn't work, check, does your controller conform to UISearchBarDelegate and secondly, does UISearchBarDelegate know about your class implementation (if you don't quite understand what am I talking about, you should learn delegation pattern starting to read here):

class YourAwesomeViewController: UIViewController, UISearchBarDelegate { // pay attention here

    @IBOutlet weak var yourSearchBar: UISearchBar!

    override func viewDidLoad() {
        super.viewDidLoad()
        self.yourSearchBar.delegate = self // and it's important too
    }
}

Further, if you need to hide the keyboard touching outside of search bar without touching the search button (the user may change his mind to search something), UITapGestureRecognizer is a simple way too to deal with that.

1. Ctrl-drag a Tap Gesture Recognizer from the Object Library to your View Controller.

2. Ctrl-drag the recently added Tap Gesture Recognizer from the document outline in the storyboard to your class implementation as IBAction.

3. Finally, write a code:

@IBAction func tapToHideKeyboard(_ sender: UITapGestureRecognizer) { self.yourSearchBar.resignFirstResponder() }

Also, don't forget to create @IBOutlet for the search bar to have an access inside your class implementation.

Both variants above work well in my project.

Swift 4+:

You can try, creating a tap gesture and add in the self.view

let singleTapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.singleTap(sender:)))
singleTapGestureRecognizer.numberOfTapsRequired = 1
singleTapGestureRecognizer.isEnabled = true
singleTapGestureRecognizer.cancelsTouchesInView = false
self.view.addGestureRecognizer(singleTapGestureRecognizer)

and in selector func you call self.searchBar.resignFirstResponder

@objc func singleTap(sender: UITapGestureRecognizer) {
    self.searchBar.resignFirstResponder()
}

You can use a general UIViewController extension

1. Just add a new swift file on the project and paste the following code snippet

Code

extension UIViewController {

    func hideKeyboardWhenTappedAround() {
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard(_:)))
        tap.cancelsTouchesInView = false
        view.addGestureRecognizer(tap)
    }
    
    @objc func dismissKeyboard(_ sender: UITapGestureRecognizer) {
        view.endEditing(true)
        
        if let nav = self.navigationController {
            nav.view.endEditing(true)
        }
    }
 }

2. Now call hideKeyboardWhenTappedAround() from viewDidLoad method where you want keyboard hiding feature.

class MaCaveViewController: UIViewController, UISearchBarDelegate {
    
    @IBOutlet weak var searchBar: UISearchBar!

    override func viewDidLoad() {
        super.viewDidLoad()
        searchBar.delegate = self
    }

    // When button "Search" pressed
    func searchBarSearchButtonClicked(_ searchBar: UISearchBar){
        print("end searching --> Close Keyboard")
        self.searchBar.endEditing(true)
    }
}

This works very well for me.

we can do this with following methods

    func searchBarTextDidBeginEditing(searchBar: UISearchBar) {
        searchBar.showsCancelButton = true;
    }
    
    func searchBarTextDidEndEditing(searchBar: UISearchBar) {
        searchBar.showsCancelButton = false;
    }

This works for me in Swift 4

   func searchBarSearchButtonClicked(_ searchBar: UISearchBar){

    self.searchBar.endEditing(true)

    }
