Uitextfielddelegate does not hide the keyboard

Question

Good night, fellas

I’m having a little trouble with Uitextfielddelegate. I intend that when the user clicks the return key (Back) the keyboard disappears for a few moments and goes back to textField to write something again. But the Return key is ignored in the execution act and the keyboard does not disappear. from a look at the terminal

import UIKit

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, UITextFieldDelegate {

    @IBOutlet weak var itextField: UITextField!

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

Answer 1

Hello

Try:

itextField.endEditing(true) 

Answer 2

In his Main.storyboard, click on Textfield, go to Attributes Inspector and look for the Keyboard option.

There you have the option to make it disappear:

Try the option Dismiss.

Unfortunately I do not know how to make the keyboard disappear for a few moments, but using code below, I think the keyboard will descend very fast and soon return.

  func dismissKeyboard(){

    view.endEditing(true)
                   }

 func textFieldShouldReturn(_ textField: UITextField) -> Bool {

    if (textField == self.itextfield) {

        dismissKeyboard()
        itextfield.becomeFirstResponder()

    }else{

    return true

}
}

Answer 4

I solved the problem of hiding the keyboard only in delegate to textField in the View controller. Click on Textfield Press control+click drag the web to the view controller shortcut at the top of the Scene view controller. choose the delegate option.

Answer 5

To use delegate functions you need to assign item delegate.

Just make itextField.delegate = self
