Re: UIPageViewController page index woes
So apparently the page control is entirely transparent by default. Try adding
this to your app delegate's didFinishLaunching... method:
UIPageControl * pageControl = [UIPageControl appearance];
pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
pageControl.currentPageIndicatorTintColor = [UIColor darkGrayColor];
pageControl.backgroundColor = [UIColor clearColor];
This will apply a default customization to every page control in your app. The
other way to apply non-transparent colors is to loop through all the sub-views
of your UIPageViewController's view and look for the one who's kindOfClass is
[UIPageControl class] and set whatever colors you want on it. This *might* be a
gray area in terms of using undocumented API though.

Re: UIPageViewController page index woes
I'm having the same issue. When I dive into the view hierarchy in the debugger
I see the page control inside the UIPageViewController's view, but it's frame
is {0,0,0,0}.

Did you set the transition style to UIPageViewControllerTransitionStyleScroll? The documentation says: If both of the methods in “Supporting a Page Indicator” are implemented *and* the page view controller’s transition style is UIPageViewControllerTransitionStyleScroll, a page indicator is visible.

UIPageViewController page index woes
I've implemented the two page index methods in the dataSource, but I'm not getting a page indicator. Where does it appear, near the bottom? I see my methods are being called. I also don't know how to determine the current page index. -presentationIndexForPageViewController: should return an NSInteger, but I don't know how to tell which view controller is currently being shown. I'm not even sure why I have to implement this, since just telling it the total count should be enough for it to figure things out. Any ideas? The example code doesn't use the page index.
