проблема с performSegueWithIdentifier и RootViewController

Question

им с помощью этой строки кода, чтобы выполнить SEGUE

[self.window.rootViewController performSegueWithIdentifier:@"viewMessage" sender:self];

, но так как я зову rootViewController его попытки искать viewMessage idenifier в моем loginViewController, когда мне это нужно, чтобы быть ищет его в friendsListTableViewController Я пробовал просто объявить [self performSegueWithIdentifier:@"viewMessage" sender:self];, но у меня есть два @implementations и self продолжает распознаваться как JBSlidingTableViewCell1, и поскольку его UITableView не распознает performSeguqWithIdentifier, я пробовал [friendsListTableViewController performSegueWithIdentifier:@"viewMessage" sender:self];, но все, что я получаю, это t hat performSegueWithIdentifier не является исключением этого класса, когда на самом деле это UIViewController ...

Im пытается воздержаться от публикации кода как можно больше, так как есть слишком много, но я просто хотел посмотреть, есть ли способ заставить performSeguqWithIdentifier, чтобы указать на мою friendsListTableViewController вместо моего loginViewController

Answer 1

Учитывая структуру вашего приложения, похоже, единственным способом, чтобы получить ссылку на friendsListTableViewController чтобы посмотреть цепочку представлений. Так, методом nextResponder будет возвращать контроллер представления о целях, что он отвечает за следующее вы должны получить ссылку на требуемый контроллер представления из файла реализации пользовательского элемента ячейки:

self.superview.superview.nextResponder 

В этом случае SuperView ячейки является табличным представлением, и это представление таблицы находится в подчинении основного вида контроллера, поэтому self.superview.superview доставит вас к self.view контроллера. В документации для следующегоResponder сказано следующее: «UIView реализует этот метод, возвращая объект UIViewController, который управляет им (если он есть)». Итак, вызывая nextResponder на self.view контроллера, вы получаете контроллер.
