xCode: setView always portrait though device in Landscape
===

I have encountered a problem developing an iPad app with xCode.

When I load a view into my rootViewController like this

    [self setView:viewController.view];

The view is always displayed in Portrait even though the device is rotated to landscape. 

I checked all options and tried changing the shouldAutoRotateToOrientation method and it seems to have nothing to do with it. 
If I rotate the device to portrait and then back to landscape it works.

Does anybody know why this is happening?

Best regards,

Matteo
