阅读更多关于 iOS - Alamofire 网络请求

前言 Alamofire 是 Swift 语言的 HTTP 网络开发工具包，相当于 Swift 实现 AFNetworking 版本。当然，AFNetworking 非常稳定，在 Mac OSX 与 iOS 中也能像其他 Objective-C 代码一样用 Swift 编写。不过 Alamofire 更适合 Swift 语言风格习惯（Alamofire 与 AFNetworking 可以共存一个项目中，互不影响）。Alamofire 取名来源于 Alamo Fire flower。 Alamofire 的核心主要是试图简化 iOS 中 HTTP 网络连接，它通过使用 NSURLSession 以及 Foundation URL Loading System 来创建一个 Swift 本地的网络访问接口，从而实现令人难以置信效率的任务。 1、Alamofire Alamofire 功能： Chainable Request / Response methods URL / JSON / plist Parameter Encoding Upload File / Data / Stream Download using Request or Resume data Authentication with NSURLCredential Progress Closure &

最近，AFNetworking 的作者 Mattt Thompson 提交了一个新的类似于 AFNetworking 的网络基础库，并且是专门使用最新的 Swift 语言来编写的，名为： Alamofire AFNetwork 的前缀 AF 是 Alamofire 的缩写，因此这个新的库名称其实是根据 Swift 的约定来进行命名的。在本教程的第一部分中，我们将带领大家使用 Alamofire 来制作一个图片库应用，其来源是 500px.com 。在这个过程中，您可以学习到如何使用 Alamofire 中的重要组件，以及了解在应用中处理网络请求的某些重要的知识点。本教程的第二部分将基于第一部分所制作的应用，并为其增加一些好用的功能。您可以通过这个过程学习到更多高级的 Alamofire 用法。本教程假定您已熟悉 Swift 语言以及 iOS 开发。如果不是的话，请参阅我们的其他教程。还有，本教程使用 Xcode 6.1 作为开发环境（而不是 Xcode 6.2 beta）。 > 提示：如果您已经熟悉了 Alamofire 的基本用法，那么您可以直接跳到本文的第二部分。但是请确保您已拥有消费者密钥(cunsumer key)，然后参照下文在应用中替换它。让我们开始吧首先下载本次教程的初始项目。这个项目中提供了在本教程中需要的全部 UI
