纵向和横向iPad的差异UI

Question

I would like to create an application like this:

On iphone (both portrait and landscape) and ipad portrait, I have a table view screen, tap on item row will navigate to another detail screen look like other basic application.
But when I rotate screen to go to landscape on ipad, the screen now has two section views
Here is what I did:

• Write a method isInLandscapeTablet to detect ipad landscape
• Use UINavigationController as a root controller to control all other views
• In portrait screen, push a viewcontroller contains tableview to root controller
• In landscape tablet screen, attach tableview controller and detail controller to UISplitViewController , then push it into root controller

But the problem is I can't push UISplitViewController to root controller, as it requires to be a root controller.
I wonder how I can handle this problem
And is my approach correct? Is there any other way?

Update : I change the root view controller like this

  // this snippet is in UINavigationController (I use as root viewcontroller) 
        if([self isInTabletLandscape]){
             self.splitViewController.viewControllers = [NSArray arrayWithObjects:[[CategoryViewController alloc] initWithNibName:@"CategoryViewController" bundle:nil], self.propertyLandViewController, nil];
            [[UIApplication sharedApplication].keyWindow setRootViewController:self.splitViewController];
        }else{
 // it doesn't work
            [[UIApplication sharedApplication].keyWindow setRootViewController:self];
            }
        }

After knowing the device whether it is iPad or iPhone. You Can try to remove the RootViewController.

       appDelegate.window.rootViewController = nil;

Then you set the root view controller with a new SplitViewContloller

        id objClass =[[SplitViewController alloc]initWithNibName:@"SplitViewController" bundle:nil];
        masterVC.delegate = detailVC;
        detailVC.delegate = objClass;
        [objClass setViewControllers:@[masterNavigate,detailNavigate]];

        [appDelegate.window setRootViewController:objClass];

If you are developing on iOS 8 you should use Size Classes , so you can totally change the layout depending on iPhone/iPad portrait and iPad Landscape. Unfortunately on iOS 7, size classes only differentiate iPhone and iPad.

In both case the right part (2), can be easily handle with a containerView.

My suggestion is not to use Split View Controller at all. Create a custom View Controller, which will embed your table view controller and the 2nd controller. Also, you can implement the interface-rotation logic in the custom controller you create.

https://developer.apple.com/library/ios/documentation/WindowsViews/Conceptual/ViewControllerCatalog/Chapters/SplitViewControllers.html

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   MyFirstViewController* firstVC = [[MyFirstViewController alloc] init];
   MySecondViewController* secondVC = [[MySecondViewController alloc] init];

if ( ([[UIDevice currentDevice] orientation] ==  UIDeviceOrientationPortrait)  ){

   UISplitViewController* splitVC = [[UISplitViewController alloc] init];
   splitVC.viewControllers = [NSArray arrayWithObjects:firstVC, secondVC, nil];

    window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    window.rootViewController = splitVC;
   [window makeKeyAndVisible];
 }
    else
{
// Display tableview

}
 return YES;
 }

I assume this may help you..
