hide keyboard for text field in swift programming language

Question

I have little experience in Objective-C. I want to hide the keyboard for a text field using the Swift programming language.

I also tried this

func te         


        

Answer 1

I think the Problem is with setting the Delegate.

Please set textfield Delegate to your ViewController like this

class ViewController: UIViewController,UITextFieldDelegate {

and then create the IBOutlet for your text field like this

@IBOutlet var txtTest : UITextField = nil

make sure that it is connected to your text field on your view in storyboard.

finally set its Delegate using

txtTest.delegate=self

We are almost done. Now place this delegate function into your class.

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

Hope this will solve your issue.

Answer 2

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
       }
     }
