Ipad Simulator无法自动旋转

Question

I have an an iphone app and am using shouldAutorotateToInterfaceOrientation to determine when to autorotate. On the iphone, I specify that UIInterfaceOrientationPortrait is the only allowed orientation; On the iPad, I just return YES (ie all allowed), like so:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
 if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) //also tried using [[UIDevice currentDevice] userInterfaceIdiom] to no avail
  return YES; //doesn't get here
 return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

This is in every view controller of the tab bar. When I NSLog() the [[UIDevice currentDevice] userInterfaceIdiom] , it returns 0 (or UIUserInterfaceIdiomPhone ).

Does the iPad simulator always return UIUserInterfaceIdiomPhone ?
