Rotating all the views of a TabBarController

I have a TabBarController app with 4 views. I've put on all the 4 viewControllers the autorotate method returning yes :

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return YES;
}

Thanks to this, now when i rotate the iPhone the rotation works, and even the TabBar is rotated.

In every single view i can use the following code to update to view when the rotation occurs:

- (void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    [self adjustViewsForOrientation:toInterfaceOrientation];
}

- (void) adjustViewsForOrientation:(UIInterfaceOrientation)orientation {
    if (orientation == UIInterfaceOrientationLandscapeLeft ||
        orientation == UIInterfaceOrientationLandscapeRight) {

//Here i can update the view when it goes to landscape

    }
    else if (orientation == UIInterfaceOrientationPortrait ||
             orientation == UIInterfaceOrientationPortra开发者_开发百科itUpsideDown) {

//Here i can update the view when it goes to portrait

    }

}

The problem is that when i make the rotation, only the current displayed view is updating. If later i change view clicking on the tabBar, i see the view not updated for the new orientation.

Is there a way to make all the views being aware of the orientation changed?

Ok i found it! =D

The trick is using the function:

- (void)viewWillAppear:(BOOL)animated 

Just call it in your viewControllers, and insert inside the code to update the view. Enjoy!
