Usage

@IBOutlet weak var pagerView: SSPagerView!

pagerView.dataSource = self
pagerView.delegate = self

pagerView.register(SSPagerViewCell.self, forCellWithReuseIdentifier: "SSPagerViewCell"))

DataSource

func numberOfPages(_ pagerView: SSPagerView) -> Int

func pagerView(_ pagerView: SSPagerView, cellForItemAt index: Int) -> SSPagerViewCell

Paging Option

pagerView.interitemSpacing = 20.0

pagerView.isInfinite = true

pagerView.automaticSlidingInterval = 2.0

pagerView.pagingMode = .oneStep // .scrollable .disable

pagerView.itemSize = CGSize(width: cellWidth, // view.frame.width * 0.7
                            height: cellHeight) // view.frame.height * 0.7 

pagerView.contentsInset = UIEdgeInsets(top: 100,
                                       left: (view.bounds.width - cellWidth) / 2,
                                       bottom: 100,
                                       right: (view.bounds.width - cellWidth) / 2)

Control

func scrollToPage(at index: Int, animated: Bool)

func pagerViewDidSelectPage(at index: Int)

func pagerViewWillEndDragging(_ scrollView: UIScrollView, targetIndex: Int)

Rx

SSPager provide a subspec SSPager/Rx

pod 'SSPager/Rx', '~> 1.0.0'

@IBOutlet weak var pagerView: SSPagerView!

/* 
You don't need to set delegate and datasource
`pagerView.dataSource = self`
`pagerView.delegate = self`
*/

pagerView.register(SSPagerViewCell.self, forCellWithReuseIdentifier: "SSPagerViewCell")

Binding:

// let itemColors = [UIColor.red, UIColor.orange, UIColor.yellow, UIColor.green, UIColor.blue]

Observable.just(itemColors)
    .bind(to: pagerView.rx.pages(cellIdentifier: defaultCellId)) 
    { idx, color, cell in
        cell.backgroundColor = color
    }
    .disposed(by: disposeBag)
        
pagerView.rx.pageSelected
    .bind(onNext: { idx in
        print("Page \(idx) is selected.")
    })
    .disposed(by: disposeBag)
