I have been looking all over for this but I can't seem to find it. I know how to dismiss the keyboard using Objective-C but I have no idea how to do that using Swift? Does anyone know?
override func viewDidLoad() {
super.viewDidLoad()
//Looks for single or multiple taps.
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "dismissKeyboard")
//Uncomment the line below if you want the tap not not interfere and cancel other interactions.
//tap.cancelsTouchesInView = false
view.addGestureRecognizer(tap)
}
//Calls this function when the tap is recognized.
@objc func dismissKeyboard() {
//Causes the view (or one of its embedded text fields) to resign the first responder status.
view.endEditing(true)
}
Here is another way to do this task if you are going to use this functionality in multiple UIViewControllers:
// Put this piece of code anywhere you like
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)
}
}
Now in every UIViewController, all you have to do is call this function:
override func viewDidLoad() {
super.viewDidLoad()
self.hideKeyboardWhenTappedAround()
}
This function is included as a standard function in my repo which contains a lot of useful Swift Extensions like this one, check it out: https://github.com/goktugyil/EZSwiftExtensions
An answer to your question on how to dismiss the keyboard in Xcode 6.1 using Swift below:
import UIKit
class ItemViewController: UIViewController, UITextFieldDelegate {
@IBOutlet var textFieldItemName: UITextField!
@IBOutlet var textFieldQt: UITextField!
@IBOutlet var textFieldMoreInfo: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
textFieldItemName.delegate = self
textFieldQt.delegate = self
textFieldMoreInfo.delegate = self
}
...
/**
* Called when 'return' key pressed. return NO to ignore.
*/
func textFieldShouldReturn(textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
/**
* Called when the user click on the view (outside the UITextField).
*/
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.view.endEditing(true)
}
}
You can call
resignFirstResponder()
on any instance of a UIResponder, such as a UITextField. If you call it on the view that is currently causing the keyboard to be displayed then the keyboard will dismiss.
Swift 4 working
Create extension as below & call hideKeyboardWhenTappedAround() in your Base view controller.
//
// UIViewController+Extension.swift
// Project Name
//
// Created by ABC on 2/3/18.
// Copyright © 2018 ABC. All rights reserved.
//
import UIKit
extension UIViewController {
func hideKeyboardWhenTappedAround() {
let tapGesture = UITapGestureRecognizer(target: self,
action: #selector(hideKeyboard))
view.addGestureRecognizer(tapGesture)
}
@objc func hideKeyboard() {
view.endEditing(true)
}
}
//Simple exercise to demonstrate, assuming the view controller has a //Textfield, Button and a Label. And that the label should display the //userinputs when button clicked. And if you want the keyboard to disappear //when clicken anywhere on the screen + upon clicking Return key in the //keyboard. Dont forget to add "UITextFieldDelegate" and
//"self.userInput.delegate = self" as below
import UIKit
class ViewController: UIViewController,UITextFieldDelegate {
@IBOutlet weak var userInput: UITextField!
@IBAction func transferBtn(sender: AnyObject) {
display.text = userInput.text
}
@IBOutlet weak var display: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
//This is important for the textFieldShouldReturn function, conforming to textfieldDelegate and setting it to self
self.userInput.delegate = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//This is for the keyboard to GO AWAYY !! when user clicks anywhere on the view
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.view.endEditing(true)
}
//This is for the keyboard to GO AWAYY !! when user clicks "Return" key on the keyboard
func textFieldShouldReturn(textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
}
for Swift 3 it is very simple
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
self.view.endEditing(true)
}
if you want to hide keyboard on pressing RETURN key
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
but in second case you will also need to pass delegate from all textFields to the ViewController in the Main.Storyboard
Dash's answer is correct and preferred. A more "scorched earth" approach is to call view.endEditing(true). This causes view and all its subviews to resignFirstResponder. If you don't have a reference to the view you'd like to dismiss, this is a hacky but effective solution.
Note that personally I think you should have a reference to the view you'd like to have resign first responder.
.endEditing(force: Bool)is a barbaric approach; please don't use it.
Swift 3: Easiest way to dismiss keyboard:
//Dismiss keyboard method
func keyboardDismiss() {
textField.resignFirstResponder()
}
//ADD Gesture Recignizer to Dismiss keyboard then view tapped
@IBAction func viewTapped(_ sender: AnyObject) {
keyboardDismiss()
}
//Dismiss keyboard using Return Key (Done) Button
//Do not forgot to add protocol UITextFieldDelegate
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
keyboardDismiss()
return true
}
In storyboard:
- select the TableView
- from the the right-hand-side, select the attribute inspector
- in the keyboard section - select the dismiss mode you want
Swift 3:
Extension with Selector as parameter to be able to do additional stuff in the dismiss function and cancelsTouchesInView to prevent distortion with touches on other elements of the view.
extension UIViewController {
func hideKeyboardOnTap(_ selector: Selector) {
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: selector)
tap.cancelsTouchesInView = false
view.addGestureRecognizer(tap)
}
}
Usage:
override func viewDidLoad() {
super.viewDidLoad()
self.hideKeyboardOnTap(#selector(self.dismissKeyboard))
}
func dismissKeyboard() {
view.endEditing(true)
// do aditional stuff
}

import UIKit
class ViewController: UIViewController,UITextFieldDelegate {
@IBOutlet weak var username: UITextField!
@IBOutlet weak var password: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
username.delegate = self
password.delegate = self
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func textFieldShouldReturn(textField: UITextField!) -> Bool // called when 'return' key pressed. return NO to ignore.
{
textField.resignFirstResponder()
return true;
}
override func touchesBegan(_: Set<UITouch>, with: UIEvent?) {
username.resignFirstResponder()
password.resignFirstResponder()
self.view.endEditing(true)
}
}
If you use a scroll view, It could be much simpler.
Just select Dismiss interactively in storyboard.
I found the best solution included the accepted answer from @Esqarrouth, with some adjustments:
extension UIViewController {
func hideKeyboardWhenTappedAround() {
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "dismissKeyboardView")
tap.cancelsTouchesInView = false
view.addGestureRecognizer(tap)
}
func dismissKeyboardView() {
view.endEditing(true)
}
}
The line tap.cancelsTouchesInView = false was critical: it ensures that the UITapGestureRecognizer does not prevent other elements on the view from receiving user interaction.
The method dismissKeyboard() was changed to the slightly less elegant dismissKeyboardView(). This is because in my project's fairly old codebase, there were numerous times where dismissKeyboard() was already used (I imagine this is not uncommon), causing compiler issues.
Then, as above, this behaviour can be enabled in individual View Controllers:
override func viewDidLoad() {
super.viewDidLoad()
self.hideKeyboardWhenTappedAround()
}
In Swift 4, add @objc:
In the viewDidLoad:
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.dismissKeyboard))
view.addGestureRecognizer(tap)
Function:
@objc func dismissKeyboard() {
view.endEditing(true)
}
import UIKit
class ItemViewController: UIViewController, UITextFieldDelegate {
@IBOutlet weak var nameTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
self.nameTextField.delegate = self
}
// Called when 'return' key pressed. return NO to ignore.
func textFieldShouldReturn(textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
// Called when the user click on the view (outside the UITextField).
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
self.view.endEditing(true)
}
}
As a novice programmer it can be confusing when people produce more skilled and unnecessary responses...You do not have to do any of the complicated stuff shown above!...
Here is the simplest option...In the case your keyboard appears in response to the textfield - Inside your touch screen function just add the resignFirstResponder function. As shown below - the keyboard will close because the First Responder is released (exiting the Responder chain)...
override func touchesBegan(_: Set<UITouch>, with: UIEvent?){
MyTextField.resignFirstResponder()
}
This one liner resigns Keyboard from all(any) the UITextField in a UIView
self.view.endEditing(true)
In swift you can use
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
view.endEditing(true)
}
Add this extension to your ViewController :
extension UIViewController {
// Ends editing view when touches to view
open override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
super.touchesBegan(touches, with: event)
self.view.endEditing(true)
}
}
I have use IQKeyBoardManagerSwift for keyboard. it is easy to use. just Add pod 'IQKeyboardManagerSwift'
Import IQKeyboardManagerSwift and write code on didFinishLaunchingWithOptions in AppDelegate.
///add this line
IQKeyboardManager.shared.shouldResignOnTouchOutside = true
IQKeyboardManager.shared.enable = true
I always use the following:
UIApplication.shared.keyWindow?.endEditing(true)
Or even as an extension:
extension UIApplication {
/// Dismiss keyboard from key window.
/// Example Usage: `UIApplication.endEditing(true)`.
///
/// - Parameters:
/// - force: specify `true` to force first responder to resign.
open class func endEditing(_ force: Bool = false) {
shared.keyWindow?.endEditing(force)
}
}
This way, in case the class I am trying to cancel the editing in does not have a view property or is not a subclass of UIView I can just call UIApplication.endEditing(true).
For Swift3
Register an event recogniser in viewDidLoad
let tap = UITapGestureRecognizer(target: self, action: #selector(hideKeyBoard))
then we need to add the gesture into the view in same viewDidLoad.
self.view.addGestureRecognizer(tap)
Then we need to initialise the registered method
func hideKeyBoard(sender: UITapGestureRecognizer? = nil){
view.endEditing(true)
}
swift 5 just two lines is enough. Add into your viewDidLoad should work.
let tapGesture = UITapGestureRecognizer(target: view, action: #selector(UIView.endEditing))
view.addGestureRecognizer(tapGesture)
If your tap gesture blocked some other touches, then add this line:
tapGesture.cancelsTouchesInView = false
Another possibility is to simply add a big button with no content that lies underneath all views you might need to touch. Give it an action named:
@IBAction func dismissKeyboardButton(sender: AnyObject) {
view.endEditing(true)
}
The problem with a gesture recognizer was for me, that it also caught all touches I wanted to receive by the tableViewCells.
If you have other views that should receive the touch as well you have to set
cancelsTouchesInView = false
Like this:
let elsewhereTap = UITapGestureRecognizer(target: self, action: #selector(dismissKeyboard))
elsewhereTap.cancelsTouchesInView = false
self.view.addGestureRecognizer(elsewhereTap)
override func viewDidLoad() {
super.viewDidLoad()
self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(tap)))
}
func tap(sender: UITapGestureRecognizer){
print("tapped")
view.endEditing(true)
}
Try this,It's Working
You can also add a tap gesture recognizer to resign the keyboard. :D
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let recognizer = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
backgroundView.addGestureRecognizer(recognizer)
}
func handleTap(recognizer: UITapGestureRecognizer) {
textField.resignFirstResponder()
textFieldtwo.resignFirstResponder()
textFieldthree.resignFirstResponder()
println("tappped")
}
When there is more than one text field in the view
To follow @modocache's recommendation to avoid calling view.endEditing(), you could keep track of the text field that became first responder, but that is messy and error-prone.
An alternative is to call resignFirstResponder() on all text fields in the viewcontroller. Here's an example of creating a collection of all text fields (which in my case was needed for validation code anyway):
@IBOutlet weak var firstName: UITextField!
@IBOutlet weak var lastName: UITextField!
@IBOutlet weak var email: UITextField!
var allTextFields: Array<UITextField>! // Forced unwrapping so it must be initialized in viewDidLoad
override func viewDidLoad()
{
super.viewDidLoad()
self.allTextFields = [self.firstName, self.lastName, self.email]
}
With the collection available, it's a simple matter to iterate through all of them:
private func dismissKeyboard()
{
for textField in allTextFields
{
textField.resignFirstResponder()
}
}
So now you can call dismissKeyboard() in your gesture recognizer (or wherever is appropriate for you). Drawback is that you must maintain the list of UITextFields when you add or remove fields.
Comments welcome. If there is a problem with calling resignFirstResponder() on controls that aren't first responder, or if there's an easy and guaranteed non-buggy way to track the current first responder, I'd love to hear about it!
I worked out on uisearchbar . See mine.
import UIKit
class BidderPage: UIViewController,UISearchBarDelegate,UITableViewDataSource {
let recognizer = UITapGestureRecognizer()
// Set recogniser as public in case of tableview and didselectindexpath.
func searchBarTextDidBeginEditing(searchBar: UISearchBar)
{
recognizer.addTarget(self, action: "handleTap:")
view.addGestureRecognizer(recognizer)
}
func handleTap(recognizer: UITapGestureRecognizer) {
biddersearchbar .resignFirstResponder()
}
func searchBarTextDidEndEditing(searchBar: UISearchBar)
{
view .removeGestureRecognizer(recognizer)
}
I prefer this one-liner:
view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: "dismissKeyboardFromView:"))Just put that in the override viewDidLoad function in whichever subclassed UIViewController you want it to occur, and then put the following code in a new empty file in your project called "UIViewController+dismissKeyboard.swift":
import UIKit
extension UIViewController {
// This function is called when the tap is recognized
func dismissKeyboardFromView(sender: UITapGestureRecognizer?) {
let view = sender?.view
view?.endEditing(true)
}
}
