J'essaie de reproduire une minuterie simple avec RxSwift.
J'ai une pause/lecture button
uniquement qui fonctionne pour la pause et la reprise.
gameTimer = Observable<NSInteger>.interval(1, scheduler: MainScheduler.instance)
.subscribeNext({ sec -> Void in
print("\(sec) s")
}).addDisposableTo(disposeBag!)
pauseResumeButton.rx_tap
.map{ !self.isRunning.value }
.startWith(true)
.bindTo( isRunning )
.addDisposableTo(disposeBag!)
isRunning
est une variable <Bool
> évidemment. Je peux arrêter les paramètres de la minuterie disposeBag = nil
mais je ne peux pas l'interrompre .... j'ai essayé de filtrer les événements mais le nombre continue évidemment d'augmenter ...
Quelqu'un peut-il m'aider? Merci!
Un petit truc:
class ViewController: UIViewController {
let isRunning = Variable(true)
override func viewDidLoad() {
super.viewDidLoad()
isRunning.asObservable()
.debug("isRunning")
.flatMapLatest { isRunning in
isRunning ? Observable<Int>.interval(1, scheduler: MainScheduler.instance) : .empty()
}
.flatMapWithIndex { (int, index) in Observable.just(index) }
.debug("timer")
.subscribe()
.addDisposableTo(disposeBag)
navigationItem.rightBarButtonItem!.rx.tap
.subscribe(onNext: { [unowned self] in
self.isRunning.value = !self.isRunning.value
})
.addDisposableTo(disposeBag)
}
}
Résultat:

2016-12-17 20:53:11.414: isRunning -> subscribed
