ios - prepareForSegue 从未调用过

Question

我正在使用 SWRevealViewController 构建侧边栏菜单。从菜单(UITableView)中选择一个元素时，我有选择正确 Controller 的方法。 segue 标识符/名称在 Storyboard中配置。

- (void) prepareForSegue: (UIStoryboardSegue *) segue sender: (id) sender
{
    NSLog(@"Tapped");
    // Set the title of navigation bar by using the menu items
    NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
    UINavigationController *destViewController = (UINavigationController*)segue.destinationViewController;
    destViewController.title = [[_menuItems objectAtIndex:indexPath.row] capitalizedString];

    // Set the photo if it navigates to the PhotoView
    if ([segue.identifier isEqualToString:@"showToday"]) {
        [segue destinationViewController];

    }
    if ([segue.identifier isEqualToString:@"showCountries"]) {
        [segue destinationViewController];

    }


    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];
        };

    }

}

但是从侧栏菜单中选择项目时没有任何反应。可能是什么问题？谢谢您的帮助。

我的错是选择“附件操作”而不是“选择继续”“显示 View Controller ”。
