Do something when click on Return Button

[nahouto]

Hi,

I don't understand how to do something when the user press on return button.
I tried that in viewDidLoad :

    returnKeyHandler = IQKeyboardReturnKeyHandler(controller: self)
    emailTextField.delegate = returnKeyHandler
    passwordTextField.delegate = returnKeyHandler
    self.view.setCustomDoneTarget(self, selector: "loginButton:")

But it doesn't work...

Something else, I am confused about the custom Done Button (in the bar above the keyboard) and the keyboard Return button (bottom right).

Thank your for this pod !

For the return button. Either you can use IQKeyboardReturnHandler, and set it's delegate to self. You don't need to set email, password textfield delegate to returnKeyHandler. Now you can implement textfieldShouldReturn and you can do your custom work there.

CustomDoneTarget is a different thing and doesn't bound with return key.

It doesn't work. I tried to use your keyboardManager for tableView with textViews in cells. Arrow button works perfectly, but return key doesn't work as expected.
I was forced to implement it manually:

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
    if([text isEqualToString:@"\n"]) {
        IQKeyboardManager *keyboardManager = [IQKeyboardManager sharedManager];
        if (keyboardManager.canGoNext) {
            [keyboardManager goNext];
        } else {
            [keyboardManager resignFirstResponder];
        }
        return NO;
    }

    return YES;
}

I tried that :

    var returnKeyHandler: IQKeyboardReturnKeyHandler!
    override func viewDidLoad() {
        returnKeyHandler = IQKeyboardReturnKeyHandler(controller: self)
        returnKeyHandler.delegate = self
    }

    // do when click on bottom right button (next button or done button)
    func textFieldShouldReturn(textField: UITextField) -> Bool {
        switch textField {
            // move to the next text field
        case emailTextField:
            passwordTextField.becomeFirstResponder()
            // press the final button
        case passwordTextField:
            loginButton.sendActionsForControlEvents(UIControlEvents.TouchUpInside)
        default: break
        }
        return true
    }

but the textfields do not respond at all ! it is impossible to type anything in them.

Finally, I did it manually :

    override func viewDidLoad() {
        emailTextField.delegate = self
        passwordTextField.delegate = self
    }

    // do when click on bottom right button (next button or done button)
    func textFieldShouldReturn(textField: UITextField) -> Bool {
        switch textField {
            // move to the next text field
        case emailTextField:
            passwordTextField.becomeFirstResponder()
            // press the final button
        case passwordTextField:
            loginButton.sendActionsForControlEvents(UIControlEvents.TouchUpInside)
        default: break
        }
        return true
    }

and it works as expected

Write something like this, And It will work Perfectly.

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

You just need to add this code on the textFieldShouldReturn method:

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
  if IQKeyboardManager.shared.canGoNext {
    IQKeyboardManager.shared.goNext()
  } else {
    textField.resignFirstResponder()
  }
  return true
}
