force layout after update to model

[RickiG]

Excellent implementation Levi! Thanks. Why can't the UIPageViewController work like this:).
I subclassed it and found that without access to initPages() I couldn't apply a change to my data model.
So I added an updatePageLayout() method which calls initPages() internally, thought that best follows your naming convention.

Thank you Ricki!

Sorry for the slow reply; I've been traveling.

You've illuminated an oversight on my behalf, as you experienced, there's currently no way to reload the current index view controller.

I think your proposed implementation is fine, but I wonder if 'updatePageLayout' is the right choice of names since it is more akin to 'reloadData' ala UITableView or UICollectionView in that it will request new information from the data source rather than just updating layout with the data it has.

If you agree, please change the 'updatePageLayout' method to 'reloadData' and I'd be happy to accept the pull.

Many thanks!

Levi
