Updating PrepareTVC
Being a CoreDataTVC subclass, most of the legwork in configuring PrepareTVC for search has already been done. The remaining configuration will be specific to the data the table view displays. A UISearchDisplayController delegate method will also be implemented in PrepareTVC. This method will be called every time the user types text into the search bar. Provided it has a length greater than zero, a predicate will be created from the given search string. This predicate will be given to the reloadSearchFRCForPredicate method so it can reload searchFRC. The section name key path and sort descriptors provided should match those used to populate the PrepareTVC. Listing 12.10 shows the code involved.
