Core Data one-to-many relationship save
<p>Have a problem with relationships one-to-many. </p>

<p>How implement tables something like this.</p>

<p>I have a 3 lists of users,</p>

<p>1 - matched users, </p>

<p>2-all users,</p>

<p>3- selected users. </p>

<p>How i must link object to for example to <strong>Matched_users</strong> table? And after that download data from Core Data? 
I'm using NSFetchResultController in tableView, and I must link my fetch request to User table or to <strong>Matched_users</strong> table?</p>
