Calling reloadData in UITableViewController not working - ios

Question

When my app loads up it builds a menu using a UITableViewController, this menu is split in two parts. The first part has 4 items from a 'hard-coded' array, the second part is made dynamically from a list of all text files in the documents folder.
When my app runs it builds the menu and then gets files if they're needed (which the menu needs to be complete). So the second part of my menu is blank. If I run the app again the menu is fine as the files now exist.
What I want is, when the file has finished downloading, for the UITableViewController to be reloaded and so the menu rebuilt.
The number of files can and will change and will be updated often with a timestamp check carried out just before the file is downloaded.
Where the file is downloaded:
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
MenuViewController *refreshedMenu = [[MenuViewController alloc]init];
[refreshedMenu reloadTableView];
// Have also tried:
// [refreshedMenu performSelectorOnMainThread:#selector(reloadTableView)withObject:nil waitUntilDone:NO ];
[file closeFile];
}
The UITableViewController's code:
-(void)reloadTableView{
NSLog(#"reloadTableView has been run");
[self buildMenuArrays];
[self.tableView reloadData];
}
-(void)buildMenuArrays{
self.mainMenu = [NSMutableArray arrayWithObjects:#"Home", #"Exhibitor", #"Speaker", #"Workshop", nil];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDirectory = [paths objectAtIndex:0];
NSFileManager *fileManager = [[NSFileManager alloc] init];
NSArray *files = [fileManager contentsOfDirectoryAtPath:docDirectory error:nil];
self.infoMenu = [[NSMutableArray alloc] init];
for (int count = 0; count < files.count; count++) {
NSString *currentFile = [files objectAtIndex:count];
if ([currentFile rangeOfString:#".txt"].location == NSNotFound) {
NSLog(#"File %# does not contain .txt", currentFile);
} else {
NSLog(#"File %# DOES contain .txt", currentFile);
[self.infoMenu addObject:[files objectAtIndex:count]];
}
}
NSLog(#"File array = %#", self.infoMenu);
}
At the moment, the array is updated and the correct file names are there but [self.tableView reloadData]; seems to do nothing.
Any ideas?
EDIT
This seems like such a simple process but I see many other people have the same problem. IS the approach I'm taking fundamentally wrong? It seems like calling a UITableViewController's reloadData method should be very easy to do, but isn't?

Answer 1

You seem to be making a new object of MenuViewController in connectionDidFinishLoading method. This will give you a new object allright but where have you added the view of this new TableViewController object into the existing ViewController?
You need to add view of this newly created TableViewController object onto your view hierarchy.
