Answer 1

We succeeded in having a UISplitViewController inside a UITabViewController on iPad with iOS5+.

to make a long story short: it works:

• out of the box if you accept a split also in portrait;
• with a bit of work, if you want to have the master view hidden in portrait, and have it appear only upon tapping a button.

The trick in the second case is to use the IntelligentSplitViewController (see a few posts up, thanx Greg Combs) or similarly extend a UISplitVC, and be careful that the delegate of the subclass of the splitview controller is always a live object.

We have detailed the process on:

I made a sample application. and found we can do it programmatically like:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

        NSMutableArray *array = [NSMutableArray array];

        NSMutableArray *tabArray = [NSMutableArray array]; 

        UISplitViewController *splitViewConntroller = [[UISplitViewController alloc] init];

        MainViewController *viewCont = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil];
        [array addObject:viewCont];
        [viewCont release];

        viewCont = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
        [array addObject:viewCont];
        [viewCont release];




        [splitViewConntroller setViewControllers:array];

        [tabArray addObject:splitViewConntroller];

        [splitViewConntroller release];

        array = [NSMutableArray array];

        splitViewConntroller = [[UISplitViewController alloc] init];

        viewCont = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil];
        [array addObject:viewCont];
        [viewCont release];

        viewCont = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
        [array addObject:viewCont];
        [viewCont release];

        [splitViewConntroller setViewControllers:array];

        [tabArray addObject:splitViewConntroller];

        [splitViewConntroller release];

        // Add the tab bar controller's current view as a subview of the window
        [tabBarController setViewControllers:tabArray];

        [window addSubview:tabBarController.view];
        [window makeKeyAndVisible];

        return YES;
    }

Hope this helps.

See my post about retrofitting split view controllers to an existing tab bar interface: http://markivsblog.blogspot.com/2010/04/retrofitting-ipad-uisplitviewcontroller.html
