NSfetchedResultsControllerDelegate écrasé tableview

Question

Bonjour à tous, J'utilise le NSFetchedResultsControllerDelegate pour mettre à jour ma tableview. Par exemple,

// La tableview n'a aucun enregistrement.

2009-11-15 12: 25: 48,328 XXX [36890: 207] 0 // sections num avant la mise à jour // appel tableview begin mise à jour

2009-11-15 12:25: 54,277 XXX [36890: 207] insérer 0 // insérer une nouvelle section // commence à insérer des données

Answer 2

bien, alors quand nsfetchedresultscontroller voulez insérer plusieurs sections, il envoie appel à la fois d'insérer de nouvelles sections et insérer de nouvelles lignes que de nouvelles sections à son délégué; cependant, la vue de table ne veut que l'insertion de nouvelles sections. Pour résoudre cela, nous devons créer un ensemble qui a toutes les nouvelles sections. Lorsque nous insérons une nouvelle ligne, vous pouvez dire si nous devons insérer ou maintenant.
