Thanx in advance for reply.

Answer 1

it's simple

1. youPasswordtextField.delegate = self ; // in viewDidLoad or any suitable place

2. in your controllers .h file conform to UITextFieldDelegate protocol

3.implement delegate method

- (BOOL)textFieldShouldReturn:(UITextField *)textField // this method get called when you tap "Go"
{
    [self loginMethod];
    return YES;
}

-(void) loginMethod
{
    // implement login functionality and navigate user to next screen
}

Answer 2

You could use the TextField Delegate method as below:-

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
  if(self.passwordTextField isFirstResponder){
     [self.passwordTextField resignFirstResponder];    //Resign the keyboard.
     [self loginMethod];     //call your login method here.
  }
  //Below case when user tap return key when done with login info then we move focus from login textfield to password textfield so as not making user to do this and for ease of user.
  else{
     [self.loginTextField resignFirstResponder];
     [self.passwordTextField becomeFirstResponder];
  }
 return YES;
}

Also, don't forgt to set delegate as below along with setting UITextFieldDelegate in yourClass.h

 self.passwordTextField.delegate = self;
 self.loginTextField.delegate = self;
