UITextField - capture return button event

Question

How can I detect when a user pressed "return" keyboard button while editing UITextField? I need to do this in order to dismiss keyboard when user pressed the "return" button.

Thanks.

Solution 1

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    return NO;
}

Don't forget to set the delegate in storyboard...

Solution 2

Delegation is not required, here's a one-liner:

- (void)viewDidLoad {
    [textField addTarget:textField
                  action:@selector(resignFirstResponder)
        forControlEvents:UIControlEventEditingDidEndOnExit];
}

Sadly you can't directly do this in your Storyboard (you can't connect actions to the control that emits them in Storyboard), but you could do it via an intermediary action.

Solution 3

SWIFT 3.0

override open func viewDidLoad() {
    super.viewDidLoad()    
    textField.addTarget(self, action: #selector(enterPressed), for: .editingDidEndOnExit)
}

in enterPressed() function put all behaviours you're after

func enterPressed(){
    //do something with typed text if needed
    textField.resignFirstResponder()
}

Solution 4

You can now do this is storyboard using the sent event 'Did End On Exit'.

In your view controller subclass:

 @IBAction func textFieldDidEndOnExit(textField: UITextField) {
    textField.resignFirstResponder()
}

In your storyboard for the desired textfield:

textField.addTarget(textField, action: #selector(resignFirstResponder), for: .editingDidEndOnExit)

Make sure your view controller is set as the textfield's delegate.

I just want to point out that UIControlEventEditingDidEndOnExit event gets sent only if textFieldShouldReturn: delegate method returns YES (without prior resigning the text field).

You don't have to implement delegation. But maybe if you do you have to return YES for this method.

Thank you. For me I set the delegate via self.yourTextField.delegate = self;. Even multiple of text fields also work.

@Praxiteles This can now be done in storyboard without requiring delegation please check answer below.
