ALDataRequestView

A simple way to show:

• Loading view while a producer or observable is started
• Reload view when a producer or observable is failed
• Empty view when a producer or observable returns an empty array or an object which inherits the Emptyable protocol and isEmpty is true

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

ReactiveSwift & RxSwift

Simply call

attachTo(dataRequestView: dataRequestView)

on your signalProducer or observable.

Make sure you implement the ALDataRequestViewDataSource:

func loadingView(for dataRequestView: ALDataRequestView) -> UIView?
func reloadViewController(for dataRequestView: ALDataRequestView) -> ALDataReloadType?
func emptyView(for dataRequestView: ALDataRequestView) -> UIView?

Examples

RxSwift

let request = URLRequest(url: URL(string: "http://httpbin.org/status/400")!)
rxDisposable = URLSession.shared.rx.data(request: request).attachToDataRequestView(dataRequestView: dataRequestView!).subscribe()

ReactiveSwift

let request = URLRequest(url: URL(string: "http://httpbin.org/status/400")!)
dataSignalProducer = URLSession.shared
    .reactive.data(with: request)
    .flatMap(.latest, transform: { (data, response) -> SignalProducer<Data, NSError> in
        if let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode > 299 {
            return SignalProducer(error: NSError(domain: "", code: httpResponse.statusCode, userInfo: nil))
        }
        return SignalProducer(value: data)
    })
    .attachTo(dataRequestView: dataRequestView!)
