Need to know when textField text is edited, and with what text?
===

I just asked this question and received this response :

    - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)replacementStr {
    // Enable "Next" if you like what's entered in the replacementStr
}

This works but the replacement string is not the whole string, just what it is adding. How can I get the whole string. My objective is to see if the string in the textField is blank or equal to a certain number (in different scenarios). Please note that the outlet to the textField doesn't work in this case because this method is being called before the text in the field changes. Please help me out if you can!
