ReactiveCocoa的使用【图】

很早之前就有看过ReactiveCocoa,那会看的时候知道是一个新的框架关于响应式编程,具体什么也没有深入研究,今天也对ReactiveCocoa这个框架的使用进行了一定的了解。在github中有对它一个简单的介绍:原文:http://www.cnblogs.com/develop-SZT/p/5284440.html

Vue报错:Property or method "XXX" is not defined on the instance but referenced during render. Make sure that this property is reactive...【图】

在Vue中定义方法或者属性时,因为粗心疏忽可以能会报该错误[Vue warn]: Property or method "search" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.属性或方法“search”不是在实例上定义的,而是在呈现期间引用的。通过初始化该属性,确保该属性是反应性的,无论是在data选...

ReactiveX 学习笔记(24)使用 RxCpp + C++ REST SDK 调用 REST API【代码】

JSON : PlaceholderJSON : Placeholder (https://jsonplaceholder.typicode.com/) 是一个用于测试的 REST API 网站。 以下使用 Task API/Rx.NET + Json.NET 调用该网站的 REST API,获取字符串以及 JSON 数据。GET /posts/1GET /postsPOST /postsPUT /posts/1DELETE /posts/1所有 GET API 都返回JSON数据,格式(JSON-Schema)如下:{"type":"object","properties": {"userId": {"type" : "integer"},"id": {"type" : "integer"},"...

[Reactive Programming] Async requests and responses in RxJS【代码】

We will learn how to perform network requests to a backend using RxJS Observables.A example of basic jquery request:console.clear(); var requestStream = Rx.Observable.just(‘https://api.github.com/users‘);//Current requestStream is just a stream //We need to subscribe it to make it work requestStream.subscribe(url => {//Preform a serve reqest by jQueryjQuery.getJSON(url).done( res => {console.lo...

ReactiveCocoa使用1

简单来说,他是一个FRP框架,把所有对象当成一个信号(signal),通过给信号添加订阅者(subScriber),不断得到来自信号的信息,他可以替代我们常用的Delegate block NSNotifcation kvo,把所有代码整合到一起,逻辑清晰1.button添加点击事件 有两种方法 根据打印结果显示 第二种更快一点;base64,iVBORw0KGgoAAAANSUhEUgAABTIAAAIqCAYAAAAXcrUsAAAMFmlDQ1BJQ0MgUHJvZmlsZQAASImVlwdYU8kWx+eWFEJCC0RASuhNkF6l9yIgHWyEJEAoMQSCih1ZVH...

[RxJS] Reactive Programming - Sharing network requests with shareReplay()【代码】

Currently we show three users in the list, it actually do three time network request, we can verfiy this by console out each network request:var responseStream = startupRequestStream.merge(requestOnRefreshStream).flatMap(requestUrl => {console.log(‘do network request‘);return Rx.Observable.fromPromise(jQuery.getJSON(requestUrl));}); We actually can use the same network request by shareReplay(1):...

ReactiveCocoa常见操作方法介绍/MVVM架构思想【代码】

1.ReactiveCocoa常见操作方法介绍。1.1 ReactiveCocoa操作须知所有的信号(RACSignal)都可以进行操作处理,因为所有操作方法都定义在RACStream.h中,因此只要继承RACStream就有了操作处理方法。1.2 ReactiveCocoa操作思想运用的是Hook(钩子)思想,Hook是一种用于改变API(应用程序编程接口:方法)执行结果的技术.Hook用处:截获API调用的技术。Hook原理:在每次调用一个API返回结果之前,先执行你自己的方法,改变结果的输出。1....

ReactiveCocoa源码拆分解析(二)

上面抽丝剥茧的把最主要的信号机制给分离开了。但在RAC中各种操作也是必不可少的,一些复杂的操作符也是有一些基础操作拼接组合而来,有点搭积木的味道。那我沿着之前的思路,写一些简单的操作符是如何实现的。 操作符之concat(拼接)concat 使用示例 QHQSignal *demoOriginSignal = [QHQSignal createSignal:^(id subscriber) { [subscriber sendNext:@"demoOriginSignal - send"]; [subscriber sendCompleted]...
