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.
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return NO;
}
Don't forget to set the delegate in storyboard...

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.
UIControlEventEditingDidEndOnExit
event gets sent only if textFieldShouldReturn:
delegate method returns YES (without prior resigning the text field).
YES
for this method.
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()
}
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:

Swift 5
textField.addTarget(textField, action: #selector(resignFirstResponder), for: .editingDidEndOnExit)
Swift version using UITextFieldDelegate :
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
resignFirstResponder()
return false
}
- (BOOL)textFieldShouldReturn:(UITextField *)txtField
{
[txtField resignFirstResponder];
return NO;
}
When enter button is clicked then this delegate method is called.you can capture return button from this delegate method.
Success story sharing
self.yourTextField.delegate = self;
. Even multiple of text fields also work.
