How to hide the keyboard when I press return key in a UITextField?

Question

Clicking in a textfield makes the keyboard appear. How do I hide it when the user presses the return key?

Answer 1

Try this,

[textField setDelegate: self];

Then, in textField delegate method

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    return YES;
}

Answer 2

Define this class and then set your text field to use the class and this automates the whole hiding keyboard when return is pressed automatically.

class TextFieldWithReturn: UITextField, UITextFieldDelegate
{

    required init?(coder aDecoder: NSCoder) 
    {
        super.init(coder: aDecoder)
        self.delegate = self
    }

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

}

Then all you need to do in the storyboard is set the fields to use the class:

Answer 3

In viewDidLoad declare:

[yourTextField setDelegate:self];

Then, include the override of the delegate method:

-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

Answer 4

Swift 4

Set delegate of UITextField in view controller, field.delegate = self, and then:

extension ViewController: UITextFieldDelegate {
    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        // don't force `endEditing` if you want to be asked for resigning
        // also return real flow value, not strict, like: true / false
        return textField.endEditing(false)
    }
}

Answer 5

If you want to hide the keyboard for a particular keyboard use [self.view resignFirstResponder]; If you want to hide any keyboard from view use [self.view endEditing:true];

Answer 6

First make your file delegate for UITextField

@interface MYLoginViewController () <UITextFieldDelegate>

@end

Then add this method to your code.

- (BOOL)textFieldShouldReturn:(UITextField *)textField {        
    [textField resignFirstResponder];
    return YES;
}

Also add self.textField.delegate = self;
