Center another nib

[Nnavick]

I called another Nib class from my first view

LoginRegister *viewController = [[LoginRegister alloc] initWithNibName:@"LoginRegister" bundle:nil];
	self.loginRegister = viewController;
	[viewController release];
   UIView *newView = loginRegister.view;
    [animationClass SetAlphaView:newView :0.5 :1];
    [self.view addSubview:newView];

the second view size is 242X225 ,
when I call it it's appears at the upper left corner and I tried to align it

 newView.center=CGPointMake(121, 112);

but it's not working,
what should I do?

Thanks
