Question

I have following Controllers, (I have selected all types orientation modes in iPad)

Here is my iPad Storyboard layout

Answer 1

There is one trick.

Fetch the status bar from the Application and rotate it.

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES];

Create and display and dismiss an empty view controller modally.

UIViewController *mVC = [[UIViewController alloc] init];
[self presentModalViewController:mVC animated:NO];
[self dismissModalViewControllerAnimated:NO];

Now your device shoud have been forced to rotate. You could now segue to a proper view controller or push one using the navigation controller.
