self.TableView not working for a TableViewController inside a ViewController?

I am making a ViewController with 2 tableviews inside it. I am structuring it like ViewController -> 2 x TableViewController classes. What I don't understand is that if I do [self.tableView reloadData] in the TableViewControllers it doesn't do anything.

If I do [tableViewA reloadData] in the ViewController it will execute the datasource methods in the TableViewController.

How do I call reloadData within the TableViewControllers?

Thanks, Alan

Edit - This is how I setup the ViewController

if(self.reviewController == nil)
{
    self.reviewController = [[ReviewerTableViewController alloc] init];
}
if(self.approverController == nil)
{
    self.approverController = [[ApproverTableViewController alloc] init];
}
[self.reviewerTableView setDataSource:reviewController];
[self.approversTableView setDataSource:approverController];

[self.reviewerTableView setDelegate:reviewController];
[self.approversTableView setDelegate:approverController];

self.reviewController.view = self.reviewController.tableView;
self.approverController.view = self.approverController.tableView;

It seems like the datasource methods run once when I initialize them, but reloadData does not work inside.

I am basically just using the datasource methods in the UITableViewControllers and I am calling a method to pull data from the net. Once I get the data, I call reloadData, but the datasource methods are not executed.

This seems very strange: you're trying to set the child UITableViewControllers' dataSource and delegates to be some local UITableViews declared (presumably) in your master view controller. It isn't supposed to work like this - the child UITableViewControllers are already the dataSource and delegate to their own implicit table views. There's no need to wired them up to separate UITableViews.

EDIT: I am assuming your "TableViewController" classes are UITableViewControllers. If not, then what you're doing may be valid, but I'd need to see all the code, headers included.

Are you calling reloadData from the rootViewController? if so, you call

[self.reviewerTableView reloadData];

Be sure the TableViewControllers' tableView properties are connected to the correct table views.

I would create a UIVIewController that implements the UITableViewDataSource and UITableViewDelegate protocols. Create two outlets, one for each tableview and make sure to wire them up in the interface builder.

then call [tableView1 reloadData];
