To use this class, simply subclass it in replace of your UIViewController.
NOTE: You must set a navigation bar tint color prior to use.
-Inside ViewDidLoad, call -initNavBarScrollingForScrollView: and pass in your scrollable view (i.e. UIScrollView, UITableView, UICollectionView)
-You can then set the animationDuration property (optional), which controls the duration for which an animation will complete if the navigation bar did not fully scroll up/down.
-Then inside your scrollView Delegate methods, call the following passing through the 'scrollView' and 'decelerate' parameters:
-startNavBarScrolling:in-scrollViewWillBeginDragging:-followScrollViewScrolling:in-scrollViewDidScroll:-endScrollViewScrolling:willDecelerate:in-scrollViewDidEndDragging:willDecelerate:
That's it! Your navigation bar should scroll along with your scrollable view. See the example for clarification.
