Question

I am stuck with this problem for a while now and I am hoping that someone can help me with this.

This is what I’ve got:

An iPad App with the following screens:

1. Homescreen with 4 buttons (no Tabbar or Navigationbar) which points to several Tabs in a coded Tabbar.
2. Screen 1 Tableview
3. Screen 2 Tableview
4. Screen 3 Tableview
5. Screen 4 Sectioned TableView

My Homescreen supports Portrait as well as Landscape rotation. When I choose an option on the homescreen (which opens a new view with a tabbar), the view gets reset to PortraitView and doesn’t support Landscape view anymore.

Ive added this code in all the viewcontrollers .m files:

- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation {
    return YES;
}

Even a default tableview gets reset to portraitview and no longer supports landscapeview.

In my firstviewcontroller I have this code which creates the Tabbar when a Button on the homescreen has been pressed.

    UITabBarController *tabbarController = [[UITabBarController alloc] init];

CategoriesOverviewController *productView = [[CategoriesOverviewController alloc] initWithNibName:@"CategoriesOverviewController" bundle:nil];
UINavigationController *TabBarItem_1 = [[UINavigationController alloc] initWithRootViewController:productView];
productView.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque; 
[productView  setTitle:@"Producten"];
productView.tabBarItem.image = [UIImage imageNamed:@"products.png"];

ShowcaseViewController *showcaseView = [[ShowcaseViewController alloc] initWithNibName:@"ShowcaseViewController" bundle:nil];
UINavigationController *TabBarItem_2 = [[UINavigationController alloc] initWithRootViewController:showcaseView];
showcaseView.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque; 
[showcaseView  setTitle:@"Showcase"];
showcaseView.tabBarItem.image = [UIImage imageNamed:@"showcase.png"];

EventMainmenuViewController *expoView = [[EventMainmenuViewController alloc] initWithNibName:@"EventMainmenuViewController" bundle:nil];
UINavigationController *TabBarItem_3 = [[UINavigationController alloc] initWithRootViewController:expoView];
expoView.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque; 
[expoView  setTitle:@"Beursagenda"];
expoView.tabBarItem.image = [UIImage imageNamed:@"calendar.png"];

CompanyViewController *companyView = [[CompanyViewController alloc] initWithNibName:@"CompanyViewController" bundle:nil];
UINavigationController *TabBarItem_5 = [[UINavigationController alloc] initWithRootViewController:companyView];
companyView.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque; 
[companyView  setTitle:@"About"];
companyView.tabBarItem.image = [UIImage imageNamed:@"About.png"];

FavoritesViewController *favoritesView = [[FavoritesViewController alloc] initWithNibName:@"FavoritesViewController" bundle:nil];
UINavigationController *TabBarItem_4 = [[UINavigationController alloc] initWithRootViewController:favoritesView];
favoritesView.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque; 
[favoritesView  setTitle:@"Favorieten"];
favoritesView.tabBarItem.image = [UIImage imageNamed:@"favorites.png"];


tabbarController.viewControllers = [NSArray arrayWithObjects: TabBarItem_1, TabBarItem_2, TabBarItem_3, TabBarItem_4, TabBarItem_5, nil];

[self presentModalViewController:tabbarController animated:YES];

tabbarController.selectedIndex = 0;

(if there is another way of doing this, please say so!)

Whats missing here!! Do I have to send some extra information with the viewcontroller?

Plz help me!! I would appreciate it very much!!

With Kind Regards,

In order for the UITabBarController to support landscape orientation, each of its view controllers needs to support it as well.

In this case, you would need to subclass UITabBarController have its shouldAutorotateToInterfaceOrientation method return YES, and then have each of its managed view controllers return YES for that orientation as well.
