title: UIScrollView and UIViews
body: <p>I want to use a UIScrollView to display multiple UIViews as the user scrolls through the UIScrollView control. I'm not worried about showing Pagination just yet.</p>
  
  <p>I already managed to implement some of it, but is not working the way I want it to. </p>
  
  <p>Currently:</p>
  
  <p>I have 3 ViewControllers with different nib files. The root view controller is the one with the UIScrollView, and it to load the rest of the view controllers.</p>
  
  <pre><code>NSMutableArray *controllers = [[NSMutableArray alloc] init];
      for (unsigned i = 0; i &lt; kNumberOfPages; i++) {
          [controllers addObject:[NSNull null]];
      }
      self.viewControllers = controllers;
      [controllers release];
  
      scrollView.pagingEnabled = YES;
      scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * kNumberOfPages, scrollView.frame.size.height);
      scrollView.showsHorizontalScrollIndicator = NO;
      scrollView.showsVerticalScrollIndicator = NO;
      scrollView.scrollsToTop = NO;
      scrollView.delegate = self;
  
      pageControl.numberOfPages = kNumberOfPages;
      pageControl.currentPage = 0;
  
      [self loadScrollViewWithPage:0];
  
  
  - (void)loadScrollViewWithPage:(int)page {
      if (page == 0) {
          PageTwo *controller2 = [viewControllers objectAtIndex:page];
          if ((NSNull *)controller2 == [NSNull null]) {
              controller2 = [[PageTwo alloc] initWithPageNumber:page];
              [viewControllers replaceObjectAtIndex:page withObject:controller2];
              [controller2 release];
          }
          // add the controller's view to the scroll view
          if (nil == controller2.view.superview) {
              CGRect frame = scrollView.frame;
              frame.origin.x = frame.size.width * page;
              frame.origin.y = 0;
              controller2.view.frame = frame;
              [scrollView addSubview:controller2.view];
          }
      }
      if (page == 1) {
  
      // replace the placeholder if necessary
      NewController *controller = [viewControllers objectAtIndex:page];
      if ((NSNull *)controller == [NSNull null]) {
          controller = [[NewController alloc] initWithPageNumber:page];
          [viewControllers replaceObjectAtIndex:page withObject:controller];
          [controller release];
      }
      // add the controller's view to the scroll view
      if (nil == controller.view.superview) {
          CGRect frame = scrollView.frame;
          frame.origin.x = frame.size.width * page;
          frame.origin.y = 0;
          controller.view.frame = frame;
          [scrollView addSubview:controller.view];
      }
      }

  <p>That's all fine... However, what I want it to do is to load the root nib first. But I'm not sure how to go about this. I know I have to increase the number of pages to 3, but when I initialize the controllers I don't know how to tell it that page == 0 should be the current view.</p>
  
  <p>Any ideas? </p>
  
  <p>Update:</p>
  
  <p>Sigh, I overlooked something.. Didn't notice that if don't specify a page at level 0 it just shows the current view hah!</p>
  
  <p>Silly me.</p>
