Make sure your UITextField has a return key type set to UIReturnKeyGo (this is for the image on the keyboard):

theTextField.returnKeyType = UIReturnKeyGo;

Then use this method to do what ever you want to do:

- (BOOL) textFieldShouldReturn:(UITextField *)textField
{
    // Tell the keyboard where to go on next / go button.
    if(textField == theTextField)
    {
        // do stuff
    }

    return YES;
}

To get the text from the textfield just call theTextField.text and save as you wish!

Swift Version

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    // Tell the keyboard where to go on next / go button.
    if textField == theTextField {
        // do stuff
    }

    return true
}

If you are adding UITextField to an UITableCell dynamically, you need to also set delegate for it:

    self.textfield.delegate = self;

also on the the header file you need to add this:

    @interface YourController: UIViewController <UITextFieldDelegate>
