title: Login ID and Password using core data iOS
body: <p>I am creating doing a project with core data.</p>
  
  <p>Now my first view is Login/password in table view controller.</p>
  
  <p>As soon as the user hits done, i want my app to compare the login and password text fields with the Entity Login (with attributes : userid and password) and then display another view with the informations associated with that user (1 to 1) relationship.</p>
  
  <p>Can any one help me with how to validate the login password and then display only the information associated with that user?</p>
  
  <p>Any help would be really appreciated. I am totally new to this.</p>
