Добавление нового контроллера вида в пользовательский скользящий ViewController с левым, правым и основным контроллером представления

Question

Я создал SlidingViewController с главными, правыми и левыми контроллерами. Теперь я хочу добавить новую функцию/метод, которая вызывается всякий раз, когда нажимается одна из ячеек таблицы видения RightViewController, чтобы переключить главный контроллер представления на то, что когда-либо контроллер просмотра связан с этой ячейкой просмотра таблицы в indexpath.row. Новый контроллер просмотра должен все же иметь доступ к этому доступному контроллеру справа и слева. У кого-нибудь есть опыт создания собственного SlidingViewController или MenuViewController, который может помочь в том, как я должен подходить к этому? Любая помощь будет с благодарностью оценена. Заранее спасибо.

Answer 1

Вы можете просто сделать это "Делегирование Design Pattern"

В RightViewController.h добавить следующие строки.

@protocol RightViewControllerDelegate <NSObject> 

@required 
    - (void)somethingClicked : (id)theObject; 

@end 

@interface RightViewController : UIViewController 

@property (nonatomic, assign) id<RightViewControllerDelegate> delegate; 

@end 

В RightViewController.m добавить следующие строки.

- (void)somethingClicked : (id)theObject 
{ 
    [_delegate somethingClicked:theObject]; 
} 

Обновление MainViewController.h со следующим кодом.

@interface MainViewController : UIViewController <RightViewControllerDelegate> 

И наконец добавить следующий код в MainViewController.m

- (void)somethingClicked : (id)theObject 
{ 
    // Perform Your Task 
}
