Password and Confirm Password in UITextField Xcode

You can write the code below on your button touch event of either sign up or login. This will check whether the strings/passwords written in both UITextFields are same or not and will prompt an alert message :

iif ([self.pwd.text isEqualToString:self.confirmpwd.text])

    {

        UIAlertView *alert= [[UIAlertView alloc]initWithTitle:@"Message" message:@"successfully" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Cancel", nil];

        

        [alert show];

    }

    

    else

    {

        UIAlertView *alert= [[UIAlertView alloc]initWithTitle:@"Message" message:@"Password mismatch" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];

        

        [alert show];

        

    }
