> touch Cartfile
- add the following line to Cartfile
github "kazuhiro4949/RxPagingKit"
- Create framework
> carthage update --platform iOS
- In Xcode, move to "Genera > Build Phase > Linked Frameworks and Library"
- Add RxPagingKit and the dependencies (PagingKit, RxSwift and RxCocoa) to your project
- Add a new run script and put the following code
/usr/local/bin/carthage copy-frameworks
- Click "+" at Input file and Add the framework path
$(SRCROOT)/Carthage/Build/iOS/RxPagingKit.framework
$(SRCROOT)/Carthage/Build/iOS/PagingKit.framework
$(SRCROOT)/Carthage/Build/iOS/RxSwift.framework
$(SRCROOT)/Carthage/Build/iOS/RxCocoa.framework
- Write Import statement on your source file
import RxPagingKit
import RxSwift
import RxCocoa
import PagingKit
Example
You can implement the binding with Reactive Programming instead of Delegate pattern.
let items = PublishSubject<[(menu: String, width: CGFloat, content: UIViewController)]>()
override func viewDidLoad() {
super.viewDidLoad()
menuViewController?.register(type: TitleLabelMenuViewCell.self, forCellWithReuseIdentifier: "identifier")
menuViewController?.registerFocusView(view: UnderlineFocusView())
// PagingMenuViewControllerDataSource
items.asObserver()
.map { items in items.map({ ($0.menu, $0.width) }) }
.bind(to: menuViewController.rx.items(
cellIdentifier: "identifier",
cellType: TitleLabelMenuViewCell.self)
) { _, model, cell in
cell.titleLabel.text = model
}
.disposed(by: disposeBag)
// PagingContentViewControllerDataSource
items.asObserver()
.map { items in items.map({ $0.content }) }
.bind(to: contentViewController.rx.viewControllers())
.disposed(by: disposeBag)
// PagingMenuViewControllerDelegate
menuViewController.rx.itemSelected.asObservable().subscribe(onNext: { [weak self] (page, prev) in
self?.contentViewController.scroll(to: page, animated: true)
}).disposed(by: disposeBag)
// PagingContentViewControllerDelegate
contentViewController.rx.didManualScroll.asObservable().subscribe(onNext: { [weak self] (index, percent) in
self?.menuViewController.scroll(index: index, percent: percent, animated: false)
}).disposed(by: disposeBag)
}
