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