Strange behavior of a UITableViewController

I'm creating an application (TabBar based) and I'm adding in the first view an UINavigationController with a UITableViewController as its rootViewController.

In the documentation I read that a TableView owned by a UITableViewController, if not stated differently, has as delegate and dataSource his own tableViewController.

The problem is that the methods of the two protocols (UITableViewDelegate, UITableViewDataSource) are never called (figured out using NSLog()).

I know I've made an error at some point, can't understand where.

I'm not sure if I understand you question correctly but here's a rough guess.

Have you set your datasource and delegate for your UITableView like somewhere in your viewDidLoad method?

Like say you got something declared like this:

@interface MyViewController <UITableViewDelegate,UITableViewDataSource>
{
    UITableView *myTableView;
}

@property (nonatomic, retain) UITableView *myTableView;

@end

In your viewDidLoad method in the implementation file, you should have something similar like:

-(void) viewDidLoad
{
    myTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];

    [myTableView setDelegate:self]; //this view controller (MyViewController) will be the delegate
    [myTableView setDataSource:self]; // data will come from this view controller itself

    ...

    [super viewDidLoad];
}

Is that what you were after?
