The presented view controller from a custom modal view is not autorotated in iOS7 - (BOOL) shouldAutorotate is not being called properly

I have a view controller that I present using a custom modal presentation

myViewController.modalPresentationStyle = UIModalPresentationCustom;
myViewController.transitioningDelegate = self;

[self presentViewController:myViewController animated:YES completion:nil];

      

        
        
        
      

    

Works as expected, but for some reason (in iOS7) the presented view controller is not autorotated when the device orientation changes. Apparently the method (represented by the view controller):

- (BOOL)shouldAutorotate {
        return YES;
}

      

        
        
        
      

    

not called in iOS7 when the device orientation changes. It is called only once when it is first shown. When I run it on iOS8 it works fine and shouldAutorotate gets called as expected. This is weird because he can only be imagined in Portrait. If I try to render the view in landscape it doesn't work. I have checked all my parent view controllers and they are all set up correctly and I have all the orientations set in my plist mode and my delegates. Does any body have any ideas as to why this works in iOS8 but not iOS7?
