Need to set reuseIdentifier, but not possible - ios

Question

my App is kind of a FileManager like the Finder under MAC OS. I can show up the root of the filesystem. But the Navigation through the directories makes problems.
In the method didSelectRowAtIndexPath i create a new instance of the current TableViewController. I set the Delegate and DataSource toself. Now the Problem that i have: The TableViewCells of the new created instance do not have a resueIdentifier. The value is NULL. And i cant set it because its read-only. So, how can i get the new cells to have a specific reuseIdentifier?
Below is my Code from the didSelectRowAtIndexPath- Method
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
if(cell.accessoryType == UITableViewCellAccessoryDisclosureIndicator)
{
NSLog(#"Entered Directory");
NSLog(#"reuseIdentifier: %#",cell.reuseIdentifier); // <- value: "fileCell"
FileTableViewController *newDir = [[FileTableViewController alloc] init];
newDir.tableView.dataSource = self;
newDir.tableView.delegate = self;
[newDir setDirectory:cell.textLabel.text];
UITableViewCell *newCell = [newDir.tableView cellForRowAtIndexPath:indexPath];
NSLog(#"reuseIdentifier NewCell: %#",newCell.reuseIdentifier); // <- is NULL
//[newDir setTitle: [fileManager currentDirectoryPath]];
/*[self setDirectory:cell.textLabel.text];
self.title = [NSString stringWithFormat:#"%#", [fileManager currentDirectoryPath]];
[self.tableView reloadData];
*/
[self.navigationController pushViewController:newDir animated:YES];
}
}
if you need more Code to help me, just let me know.
Thanks, Chris

Maybe I'm too late with this answer. But here're my thoughts.
UITableViewCell *newCell = [newDir.tableView cellForRowAtIndexPath:indexPath];
NSLog(#"reuseIdentifier NewCell: %#",newCell.reuseIdentifier); // <- is NULL
It is NULL because the tableView is not created. It will be created just after you make a push.
If you want to pass some params to your table, you should implement the variables in the FileTableViewController.h, and then in your didSelectRowAtIndexPath make use of this like:
FileTableViewController *newDir = [[FileTableViewController alloc] init];
newDir.SomeData = cell.textLabel.text;
One more important thing - if the FileTableViewController is a UITableViewController, you should not set the dataSource and delegate, especially in your current viewController. Because doing this, you set delegate to self of current viewController (not the FileTableVC that was created).
Otherwise, if FileTableVC is not UITAbleViewController Class, you should make the delegate and datasource in FileTableVC's viewDidLoad.
