title: Core Data Fetching Objects That Are in Relationship to another object
body: <p>I want to fetch objects B which has a to-many relationship with object A (ie. A -->> B). I already have A in memory. I know I could get a NSSet of the B objects from A, but would it be better to make a fetch request of the B objects (especially if I want to sort sections by date in a UITableView)?</p>
  
  <p>How would I make such a request that only gets the B objects belonging to a single object A?</p>
