loadNibNamed, view shifted up?

I am using loadView to programatically setup a UIViewController subclass and was wondering if I am getting it right. When I look at my "Interface.xib" in Interface Builder its view says 0,20,320,460 with the Status bar at the top. My question is when I build the application the view is shifted up (i.e. ignoring the Status bar). I am correcting this by setting the views frame, but am a littl开发者_高级运维e curious why its not coming in from the xib file?

- (void)loadView {
    NSLog(@"HYBRID UI: %s", __PRETTY_FUNCTION__);

    NSArray *nibArchive = [[NSBundle mainBundle] loadNibNamed:@"Interface" owner:self options:nil];
    UIView *nibView = [nibArchive lastObject];
    [nibView setFrame:[[UIScreen mainScreen] applicationFrame]];
    [self setView: nibView];
}

Maybe the view, when loaded from main bundle, doesn't get it's bound in the superview context. Hence getting (x, y) = (0, 0).
You should try to move your view to whatever (x, y) in your xib and watch if this changes anything.
