Successfully give multiple text fields the same value

Question

My app uses text fields to let users login. The login viewcontroller has a total of 4 text field IBOutlets:

IBOutlet UITextField* fldUsername;

IBOutlet UITextField* fldPassword;

@property (nonatomic, retain) IBOutlet UITextField*  nicknameTextField;
@property (nonatomic, retain) IBOutlet UITextField* secretCodeTextField;

How can one properly string the nickNameTextField with whatever value the fldUsername text field gets from the user? If fldUsername gets a "JohnnyAppleseed" value from the user, I want nicknameTextField to get the exact same value simultaneously. Proper way to achieve this using obkective c?

Thanks a lot for the updates @Jamil: I got it to work with the following line of code:

NSMutableDictionary* params =[NSMutableDictionary dictionaryWithObjectsAndKeys:command, @"command", _nicknameTextField.text = fldUsername.text, @"username", hashedPassword, @"password", nil];

Since it was already being used in for the login function, it worked by adding _nicknameTextField.text = fldUsername.text

Answer 1

you can achieve this, by implementing this delegate method.

first you need set tag of all 4 text field OR you have to check your current textfield other way

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string;{
   //check this  '**textField**' is **fldUsername** textfield 

     if(fldUsername.tag == textField.tag){
       fldUsername.text =  textField.text;
       nicknameTextField.text =  textField.text;  //override what ever it's prevous value
   }
 }
