J'ai regardé un exemple de code de searchBar et l'ai suivi jusqu'au départ, mais mon searchBar ne fonctionne pas. J'ai une application Master-Detail, et la recherche est sur le maître qui a un searchBar et un UITableView. Chaque fois que je tape quelque chose, je m'attends à ce que la vue de table diminue. Exemple quand je tape "G", il devrait montrer "Gerbera" ou des fleurs qui commencent par "G".searchBar not search
