前言 本篇文章将要学习RxSwift中数学和集合操作符,在RxSwift中包括了: toArray reduce concat toArray 将一个Observable序列转化为一个数组,并转换为一个新的Observable序列发射,然后结束. let disposeBag = DisposeBag() Observable.of(1,2,3,4,5).toArray().subscribe(onNext: {print($0)}).disposed(by: disposeBag) 运行结果:…

前言 本篇文章我们将学习RxSwift中的错误处理,包括: catchErrorJustReturn catchError retry retry(_:) catchErrorJustReturn 遇到error事件的时候,返回一个值,并且结束.更多详情 let disposeBag = DisposeBag() let sequenceFail = PublishSubject<String>() sequenceFail.catchErrorJustReturn("…

首先是 Observable 和promise的区别, 1返回值个数,Observable 可以返回0到无数个值. 2.Promise主动推送,控制着"值"何时被 "推送 "到回调函数. Observable 被动,没有被订阅的时候,它就什么也不做,而且,它既可以是同步的,又可以是异步的. import { Observable } from 'rxjs'; const foo = new Observable(subscriber => { console.…

This documentation groups information about the various operators and examples of their usage into the following pages: Creating Observables Create, Defer, Empty/Never/Throw, From, Interval, Just, Range, Repeat, Start, and Timer Transforming Observab…

RxJava的基本用法: 关于 unSubscribe() 的调用问题: There is no need to unsubscribe in onCompleted. Take a look at The Observable Contract When an Observable issues an OnError or OnComplete notification to its observers, this ends the subscription. Observers do not…

Mathematical and Aggregate Operators 本文的主题为处理 Observable 的聚合操作符. 这里的 Observable 实质上是可观察的数据流. RxJava操作符(八)Aggregate 公共代码 RxNET public static void Dump<T>(this IObservable<T> source, string name) { source.Subscribe( i => Console.WriteLine(&qu…
