    CGFloat windowHeight = parentView.window.frame.size.height;

    switch (toInterfaceOrientation) {
        case UIInterfaceOrientationLandscapeLeft:
        case UIInterfaceOrientationLandscapeRight:
            CGFloat tabBarHeight = self.tabBarController.tabBar.frame.size.height;
            frame.size.height = windowHeight + tabBarHeight;
            break;
        default:
            frame.size.height = windowHeight;
            break;
    }

    [UIView animateWithDuration:duration animations:^{
        parentView.frame = frame;
    }];
}
