Rotation Issue with drawFocus/FocusSkins

Question

I have run into an issue while trying to rotate a subclass of
UIComponent that implements IFocusManagerComponent. The rotation of
one focusable component causes all subsequent drawFocus calls to
all other focusable components to also rotate. Am I doing something
wrong or is this a bug?
The code below demonstrates the issue. Use the tab key to
cycle through the button controls. You should see, as I do, that
after three tab key presses the first button's focus skin will be
incorrectly rotated.
Thanks for your time,
Ken

Hi,
    I had the same problem. And in order to fix it I have created my custom UITabBarController.
    For that add a new cocoa touch class in your Xcode project, subclass UITabBarController. I have named my new custom class like "CustomUITabBarController".
    In CustomUITabBarController.h file we'll have this:
#import <UIKit/UIKit.h>
@interface CustomUITabBarController : UITabBarController
@end
    In CustomUITabBarController.m file the following:
#import "CustomUITabBarController.h"
@interface CustomUITabBarController ()
@end
@implementation CustomUITabBarController
- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
- (void)viewWillTransitionToSizeCGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
    //[super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
    [self.selectedViewController viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
@end
As you see I have commented [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator]; and instead I'm calling selector viewWillTransitionToSize of selected controller for our TabBarController.
Hope this will help.
