I need to show a progress bar upon an API call and hide it after the API call completes. The following is code I have written to populate a table. Where should I make calls to show and hide progress for the API being called? Is there an RxSwift way of doing this?

items = fetchAllAnswers()
items.bindTo(self.myTableView.rx_itemsWithCellIdentifier("cellIdentifier", cellType: UITableViewCell.self)){ (row, element, cell) in
    cell.textLabel?.text = element
}
.addDisposableTo(disposeBag)

func fetchAllAnswers() -> Observable<[String]>{
    let api = Observable.create { (obsever: AnyObserver<[String]>) -> Disposable in
        //progress.show()
        let items = Api.getUsers()

        obsever.onNext(items)
        obsever.onCompleted()
        //progress.hide
        return AnonymousDisposable{
            print("api dispose called")
        }
    }
    return api
}

You may to use ActivityIndicator from RxSwift repo. I using MBProgressHUD in my project. At first you need to create extension for this library:

extension MBProgressHUD {

    /**
     Bindable sink for MBProgressHUD show/hide methods.
     */
    public var rx_mbprogresshud_animating: AnyObserver<Bool> {
        return AnyObserver { event in
            MainScheduler.ensureExecutingOnScheduler()

            switch (event) {
            case .Next(let value):
                if value {
                    let loadingNotification = MBProgressHUD.showHUDAddedTo(UIApplication.sharedApplication().keyWindow?.subviews.last, animated: true)
                    loadingNotification.mode = self.mode
                    loadingNotification.labelText = self.labelText
                    loadingNotification.dimBackground = self.dimBackground
                } else {
                    MBProgressHUD.hideHUDForView(UIApplication.sharedApplication().keyWindow?.subviews.last, animated: true)
                }
            case .Error(let error):
                let error = "Binding error to UI: \(error)"
                #if DEBUG
                    rxFatalError(error)
                #else
                    print(error)
                #endif
            case .Completed:
                break
            }
        }
    }
}
import RxSwift
import RxCocoa

extension Reactive where Base: MBProgressHUD {
    public var animation: Binder<Bool> {
        return Binder(self.base) { hud, show in
            guard let view = UIApplication.shared.keyWindow?.subviews.last()! else { return }
            if show {
                if hud.superview == nil {
                    view.addSubview(hud)
                }
                hud.show(animated: true)
            } else {
                hud.hide(animated: true)
            }
        }
    }
}

Next you need to create ActivityIndicator object in your ViewController class:

let progress = MBProgressHUD()
progress.mode = MBProgressHUDMode.Indeterminate
progress.labelText = "Loading..."
progress.dimBackground = true

let indicator = ActivityIndicator()
indicator.asObservable()
    .bindTo(progress.rx_mbprogresshud_animating)
    .addDisposableTo(bag)

Next just use trackActivity() function into your sequences:

apiMethod
.trackActivity(indicator)
.subscribeNext { stringArray in 
    items.value = stringArray
}
.addDisposableTo(bag)

Hey RxSwift Observable, are you loading?, Adding loading information to your RxSwift streams request is in progress, and false when it finishes, just using the getMe() function? to know when the request loads enabling you to show or hide the loader as needed:� rsync command to with --progress option. pv command – monitor the progress of data or data transfer through a pipe. This is a recommend option for most users. rsync command to show progress bar. You need to use the --progress or -P option which show progress during file transfer. The syntax is as follows:

You have do this work in your ViewController, something like this:

var disposeBag = DisposeBag()

...

items = fetchAllAnswers()
      .subscribeOn(backgroundWorkScheduler)
      .observeOn(mainScheduler)
      .subscribe(
                onNext: { data in
                    print("onNext")
                    //show/update progress
                },
                onCompleted: {
                    print("onCompleted")
                    //hide progress
                },
                onDisposed: {
                    print("onDisposed")
                }
       ).addDisposableTo(disposeBag)

https://github.com/ReactiveX/RxSwift/blob/master/R, I m trying to show some long running task progress using UIProgressView. This is my complete and only class: class ViewController: UIViewController {. A candy to show the Progress bar with Percentage and time left calculations. Progressor is the fully customized native Progress Bar. The use case of the pod is which will do the percentage and time left calculations by own. Just you have to update the progress value from 0.0 to 1.0.

How to update UIProgressView prope…, show an activity indicator when the player stalls due to buffering; create your own progress bar and show in a different color than the progression interface, try using reactive programming with RxSwift or Combine instead). I am still a beginner in Reactive programming, and RxSwift in general. I want to chain two different operation. In my case I simply want to download a zip file from a web server, and then unzip it

AVPlayer buffering – Cyril Chandelier, Just to review, we have updated the authenticationState when the GitHub Login API is called, as we need to show the progress bar. Refer to the� RxSwift is a framework for interacting with the Swift programming language, while RxCocoa is a framework that makes Cocoa APIs used in iOS and OS X easier to use with reactive techniques. ReactiveX frameworks provide a common vocabulary for tasks used repeatedly across different programming languages.

Redux + (RxKotlin, Rxswift - how to show a progress bar. I need to show a progress bar upon an API call and hide it after the API call completes. The following is code I have written� Basic Progress Bar. A progress bar can be used to show a user how far along he/she is in a process. Bootstrap provides several types of progress bars.

Comments
  • by binding to to 'ProgressHUD' in 'viewDidLoad' it start showing it. Before calling 'trackActivity'
  • 'MBProgressHUD' start showing only when 'trackActivity' was called. I'm using it in all of my projects. If 'MBProgressHUD' showing before calling 'trackActivity' maybe you doing something wrong. You can to check my RxSwift tutorial github.com/svyatoslav-reshetnikov/ReactiveApp and see how I implemented it.
