UITextField - return return event

Question

How can I determine when the user clicked the back button while editing a UITextField? I need to do this to remove the keyboard when the user clicks the back button.

Thank.

Answer 1

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

Remember to specify the delegate in the storyboard ...

Answer 2

No delegation is required, here is one-line:

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

Unfortunately, you cannot directly do this in your storyboard (you cannot connect actions to the control that emits them on the Storyboard), but you can do this through an intermediary action.

Answer 3

SWIFT 3.0

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

the enterPressed () function contains all your actions after

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

Answer 4

Now you can do this in the storyboard using the sent event "Made an end on exit."

In your opinion, the controller subclass:

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

In your storyboard for the desired text field:

Answer 5

Swift version using UITextFieldDelegate:

 func textFieldShouldReturn(_ textField: UITextField) -> Bool { resignFirstResponder() return false } 

Answer 6

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

When you press the enter button, this delegate method is called. You can grab the return button from this delegate method.
