title: iOS core data "joining" two "tables"
body: <p>I have to Entity in core data:</p>
  
  <p>GAMES and PLAYERS</p>
  
  <p>GAMES - look like this (simplified):
  board
  userid</p>
  
  <p>PLAYERS
  userid
  name</p>
  
  <p>PLAYERS is unique</p>
  
  <p>I need to select GAMES and add the PLAYERS.name column to this result.</p>
  
  <p>I have set up all core data and relationships, and can select from the "tables" and put it in a array and in a Tableview.</p>
  
  <pre><code>NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
  NSEntityDescription *entity = [NSEntityDescription entityForName:@"GAMES" inManagedObjectContext:context];
  [fetchRequest setEntity:entity];
  GamesARRAY =[context executeFetchRequest:fetchRequest error:&amp;error];
  </code></pre>
  
  <p>and so on....</p>
  
  <p>But HOW do i select, or access the data from players table? I know all the basics and theory, but I really need code examples. Not just answers like: use NSSet or like that..</p>
