Я использую прототип Storyboard UITableViewCell и получаю нуль, когда вызывается dequeueReusableCellWithIdentifier в cellForRowAtIndexPath. Я трижды проверил, что Идентификатор Xcode для прототипа tableviewcell является "PersonCell", удалил ячейку прототипа и снова добавил ее, закомментировал наследование UISearchDisplyDelegate и UISearchBarDelegate для UITableViewController и по-прежнему получает нуль. Я в тупике. Кто-нибудь сталкивался с этим?
