Changing screen orientation without rotation and view resizing animations

I need to instantly and without rotation animation change the screen orientation (and accordingly the size of the frame self.view in the UIViewController). If I do it like this in UIViewController:

- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
{
     [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];

     [CATransaction begin];
     [CATransaction setDisableActions:YES];
     [coordinator animateAlongsideTransition:^(id<UIViewControllerTransitionCoordinatorContext> context) {
         [self.view setFrame:CGRectMake(0, 0, size.width, size.height)];
     } completion:^(id<UIViewControllerTransitionCoordinatorContext> context) {
         [CATransaction commit];
     }];
}

Then, at the moment the screen orientation changes to, I see a flickering of view. How can I do what is necessary?
