从过滤的tableView执行Segue

Question

我为tableView构建了一个UISearchBar，它可以过滤用户名...到目前为止非常好，但是现在我想在tableView的单元格被过滤时执行搜索，但是只要我单击一个单元格，回到originViewController

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    dismiss(animated: true) {
        print("Dismiss completed")
        let user = self.users[indexPath.row]
        self.messagesController?.showChatControllerForUser(user)
        }
    searchController.isActive = false
    }

searchBar函数

func searchBarIsEmpty() -> Bool {
    // Returns true if the text is empty or nil
    return searchController.searchBar.text?.isEmpty ?? true
}

func isFiltering() -> Bool {
    return searchController.isActive && !searchBarIsEmpty()
}

func filterContentForSearchText(_ searchText: String, scope: String = "All") {
    filtered = users.filter({( user : User) -> Bool in
        return (user.name?.lowercased().contains(searchText.lowercased()))!
    })
    tableView.reloadData()
}

编辑：

func showChatControllerForUser(_ user: User) {
    let chatLogController = ChatLogController(collectionViewLayout: UICollectionViewFlowLayout())
    chatLogController.user = user
    navigationController?.pushViewController(chatLogController, animated: true)
}
