If you have a Navigation Controller managing these views, the shouldAutorotate method won't be called. You would have to subclass UINavigationController and override methods shouldAutorotate andsupportedIntervalOrientations.

From the docs:

Now, iOS containers (such as UINavigationController) do not consult their children to determine whether they should autorotate

Edit-----

As mentioned below by Lomax, subclassing UINavigationController is discouraged by Apple. You should try a category instead (this SO question explains it well):

@implementation UINavigationController
-(BOOL)shouldAutorotate
{
    // your code
}

-(NSUInteger)supportedInterfaceOrientations
{
    (...)
}

@end
