In fact, this is the very reason we want to use the fetched results controller in this case.

I’d recommend also taking a look at some of the Apple samples out there – they have 5 different Core Data examples currently available and they all show different and interesting aspects of things you can do.
A good exercise would be to continue this example to add in the detail view that we created in the SQLite tutorial, or to add in support for adding/editing/deleting items.

Also, if you have any advice about Core Data or gotchas that you’ve encountered with Core Data in your projects, please share!
We are going to override the get method for our property so that it checks to see if the fetched results controller exists first.
If it does exist, it will return it, otherwise it will create it.
The problem happens when one of those users accepts a request, at which point they should be shown on the list but since they were previously excluded from the fetch request, they won't be added.
