将数据从 UITableViewCell 推送到 UINavigationController

我有一个 UISearchDisplaycontroller，我必须将信息推送到文本字段，并需要将其链接到导航视图控制器。

这是我的代码 -

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"showRecipeDetail"]) {
    NSIndexPath *indexPath = nil;
    Recipe *recipe = nil;

    if (self.searchDisplayController.active) {
        indexPath = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
        recipe = [searchResults objectAtIndex:indexPath.row];
    } else {
        indexPath = [self.tableView indexPathForSelectedRow];
        recipe = [recipes objectAtIndex:indexPath.row];
    }

    RecipeDetailViewController *destViewController = segue.destinationViewController;
    destViewController.recipe = recipe;



}

}

您的 UINavigationController 层次结构错误或放置错误。
