Hi,
from UIViewController Class Reference:
+- (void)loadView+
+%< (SNIP) >% -+
+The default implementation of this method looks for valid nib information and uses that information to load the associated nib file. If no nib information is specified, the default implementation creates a plain UIView object and makes it the main view.+
+If you override this method in order to create your views manually, you should do so and assign the root view of your hierarchy to the view property. (The views you create should be unique instances and should not be shared with any other view controller object.) Your custom implementation of this method should not call super.+
+If you want to perform any additional initialization of your views, do so in the viewDidLoad method. In iOS 3.0 and later, you should also override the viewDidUnload method to release any references to the view or its contents.+
So if you want to create a view (background image) which loads from a nib you need to add additional views (scrollview) in viewDidLoad by adding the as subviews to self.view.
- (void)viewDidLoad
// Step 1: make the outer paging scroll view
CGRect pagingScrollViewFrame = [self frameForPagingScrollView];
pagingScrollView = [[UIScrollView alloc] initWithFrame:pagingScrollViewFrame];
pagingScrollView.pagingEnabled = YES;
//pagingScrollView.backgroundColor = [UIColor blackColor];
pagingScrollView.showsVerticalScrollIndicator = NO;
pagingScrollView.showsHorizontalScrollIndicator = NO;
pagingScrollView.contentSize = CGSizeMake(pagingScrollViewFrame.size.width * [self imageCount],
pagingScrollViewFrame.size.height);
pagingScrollView.delegate = self;
[self.view addSubView:pagingScrollView];
// Step 2: prepare to tile content
recycledPages = [[NSMutableSet alloc] init];
visiblePages = [[NSMutableSet alloc] init];
[self tilePages];
