Close iOS Keyboard by touching anywhere using Swift

Question

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?

Answer 1

override func viewDidLoad() {     super.viewDidLoad()                //Looks for single or multiple taps.       let tap = UITapGestureRecognizer(target: self, action: #selector(UIInputViewController.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(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)     }  }
