There should be no reason (or need) to set the status bar orientation in the
code above. Just return YES if the requested rotation is landscape, like the
below:
-
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
As a rule -shouldAutorotateToInterfaceOrientation: should not have any side
effects, primarily because it may be called in situations other than when your
view controller currently arbitrates the supported orientations (most commonly
this case is a UITabBarController).
