A ViewPager with NavigationBar component based on UIPageViewController and UICollectionView, which is a convenience way to supply and manager each viewController.

I want to make UIPageViewController more intuitive for using it, like UITableView, and supply a navigationBar quickly and simply.

More importantly, when UIPageViewController scroll continuously, pageControl sometimes will get wrong index, this viewPager can help you solve it.

There are some standard dataSource and delegate implemented for generating each page and navigationBar, each of these classes have simple sample code showing in the Pod Example for BmoViewPager.

give page count and each page controller, just like using tableView

func bmoViewPagerDataSourceNumberOfPage(in viewPager: BmoViewPager) -> Int {
    return YourPageCount
}
func bmoViewPagerDataSource(_ viewPager: BmoViewPager, viewControllerForPageAt page: Int) -> UIViewController {
    return YourPageViewController
}

using default style, only need to give the each page title

func bmoViewPagerDataSourceNaviagtionBarItemTitle(_ viewPager: BmoViewPager, navigationBar: BmoViewPagerNavigationBar, forPageListAt page: Int) -> String? {
    return YourPageTitleString
}

navigation item title can custom attributed

func bmoViewPagerDataSourceNaviagtionBarItemNormalAttributed(_ viewPager: BmoViewPager, navigationBar: BmoViewPagerNavigationBar, forPageListAt page: Int) -> [String : Any]? {
    return [
        NSForegroundColorAttributeName : UIColor.lightGray,
        NSFontAttributeName : UIFont.systemFont(ofSize: 14.0)
    ]
}

func bmoViewPagerDataSourceNaviagtionBarItemHighlightedAttributed(_ viewPager: BmoViewPager, navigationBar: BmoViewPagerNavigationBar, forPageListAt page: Int) -> [String : Any]? {
    return [
        NSForegroundColorAttributeName : UIColor.red,
        NSFontAttributeName : UIFont.boldSystemFont(ofSize: 14.0)
    ]
}

if you don't want use default style, you can custom your own background view and highlighted background view

InfiniteScroll	Custom NavigationBar animation

native pageController have a default pageControl if you implement the func presentationCount(for pageViewController: UIPageViewController) -> Int and func presentationIndex(for pageViewController: UIPageViewController) -> Int but sometimes the index have a little bug, if you feel the way too, hope it help you

Native PageController continuously scroll	continuously scroll using bmoViewPager
