Segues不会将用户从“滑出”菜单带到下一个视图

Question

所以，我开发了一个带有滑出式菜单的应用程序，我在那里使用了AppCoda（http://www.appcoda.com/ios-programming-sidebar-navigation-menu/）中的教程和项目文件。

这个滑出式菜单是由JSON从数据库创建的，并且正在按预期工作，但是，当我按下其中一个单元格时，它将不会加载新的ViewController。

我尝试过使用此代码，以使其正常工作：

- (void) prepareForSegue: (UIStoryboardSegue *) segue sender: (id) sender {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
Rules *currentRule = [rulesArray objectAtIndex:indexPath.row];
UINavigationController *destViewController = (UINavigationController*)segue.destinationViewController;
destViewController.title = [currentRule.ruleTitle capitalizedString];

if ([segue.identifier isEqualToString:@"showRule"]) {
    PhotoViewController *pvc = (PhotoViewController*)segue.destinationViewController;
    pvc.people = currentRule.rulePeople;
    pvc.content = currentRule.ruleText;

    [self.navigationController pushViewController:pvc animated:YES];
}

if ([segue isKindOfClass: [SWRevealViewControllerSegue class]]) {
    SWRevealViewControllerSegue *swSegue = (SWRevealViewControllerSegue*) segue;

    swSegue.performBlock = ^(SWRevealViewControllerSegue* rvc_segue, UIViewController* svc, UIViewController* dvc) {
        UINavigationController* navController = (UINavigationController*)self.revealViewController.frontViewController;
        [navController setViewControllers: @[dvc] animated: NO ];
        [self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];
    };
} }

结合两个视图的segue附加到TableView（菜单）和PhotoView。谁能看到我做错了什么？
