hide keyboard for text field in swift programming language

Here we go:

1. Add a textField to your View
2. Create a new Swift file
3. Set this new file as a Class for that particular View
4. Add a TextField to your View
5. Create an Outlet for the textfield (my is named "txtField" !)
6. Substitute any code in the Swift Class file with this:


import Foundation
import UIKit

//01 create delegation
class MyViewController2: UIViewController,UITextFieldDelegate {

@IBOutlet weak var txtField: UITextField!=nil

override func viewDidLoad() {
super.viewDidLoad()
// additional setup after loading the view

//02 set delegate to textfield
txtField.delegate = self
}

//03 textfield func for the return key
func textFieldShouldReturn(textField: UITextField) -> Bool {
txtField.resignFirstResponder()
return true;
}

//textfield func for the touch on BG
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
txtField.resignFirstResponder()
self.view.endEditing(true)
}

override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
//dispose of any resources that can be recreated
}
}


7. Try it out, be happy & say thanks !

Like @spfursich said, The best way is, when user touch anywhere above the keyboard the keyboard will disappear. Here is the code :

override func viewDidLoad() {
super.viewDidLoad()

var tap:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "DismissKeyboard")
self.view.addGestureRecognizer(tap)
}

func DismissKeyboard(){
self.view.endEditing(true)
}

You can try this code to have the "return" key execute code.

func textFieldShouldReturn(textField: UITextField) -> Bool{
textField.resignFirstResponder()
performAction()
return true;
}

func performAction(){

//execute code for your action inside this function

}

Hope this can help you.

Just override the UIViewController method called "touchesBegan" and set endEditing to true. Just like this:

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

First you need to set `delegate` for your textfield then you need to include `resignFirstResponder()` to hide keyboard when press return button of keybaord.

func textFieldShouldReturn(textField: UITextField!) -> Bool // called when 'return' key pressed. return NO to ignore.
{
textField .resignFirstResponder()
return true;
}
