Question

Did you notice that UINavigationBar is not set anymore when creating a UITableView, even after giving it a title or a button?

Now i’m going mad on how to put a navigation bar over my UITableView. It seems really impossible. I tried to add to my tableView a subview with the Navigation Bar, but seems worthless, because when I scroll down, the navigation bar scrolls down as wellm and it shouldn’t.

Any ideas on how to implement it?

EDIT

Well, as always I went on File -> New -> File.. -> UITableView. Then i set a bit of code and when I wrote

self.navigationItem.title = @"MyTitle";
self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;

and tried to test on Simulator, no Navigation Bar appeared.

My init code:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = @"TabTitle";
        self.tabBarItem.image = [UIImage imageNamed:@"img.png"];
        self.view.backgroundColor = [UIColor scrollViewTexturedBackgroundColor];

    }
    return self;
}

I can’t explain why it doesn’t appear anymore. I also tried to create a new project and import my classes from a project where the navigation bar appeared, but same result there too.

EDIT2*

The app is a tabBased application.
Here is the code took from the App delegate used to set up the tabBar.

 UIViewController *viewController1, *viewController4;
    UITableViewController *viewController2, *viewController3;
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        viewController1 = [[FirstViewController alloc] initWithNibName:@"First_iPhone" bundle:nil];
        viewController2 = [[Tips alloc] initWithNibName:@"Table" bundle:nil];
        viewController3 = [[Favorites alloc] initWithNibName:@"Test_iPhone" bundle:nil];
        viewController4 = [[SecondViewController alloc] initWithNibName:@"Second_iPhone" bundle:nil];
    }

You are initing an UITabBarController and set 4 UIViewControllers as the corresponding UITabbarViewControllers. Since two of them are normal UIViewControntroller and two are UITableViewController there can not be a navigation bar. You have to load the viewController where you’d like the navbar form a UINavigationController. The correct way would be (assuming vc3 is the one where you’d like the navbar):

UIViewController *viewController1, *viewController4;
UITableViewController *viewController2, viewController3;
UINavigationController *vc3NavController;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
    viewController1 = [[FirstViewController alloc] initWithNibName:@"First_iPhone" bundle:nil];
    viewController2 = [[Tips alloc] initWithNibName:@"Table" bundle:nil];
    viewController3 = [[Favorites alloc] initWithNibName:@"Test_iPhone" bundle:nil];
    vc3NavController = [[UINavigationController alloc] initWithRootViewController:viewController3];        
    viewController4 = [[SecondViewController alloc] initWithNibName:@"Second_iPhone" bundle:nil];
}

Then load the vc3NavController instead of viewController3 as the corresponding tab.
So you have: UITabBarController -> UINavigationController -> YourViewController

Maybe Creating a Navigation Interface will help you too.
