iOS 通用缓存：HanekeSwift

Haneke 是个采用 Swift 编写的轻量级 iOS 通用缓存。示例：

初始化一个数据缓存：

let cache = Cache<NSData>("my-files")

Haneke 同时包括一个零配置的图片缓存，可以自动缩放。 示例：

imageView.hnk_setImageFromURL(url)


它的设计是超简单易用。这里是你如何初始化一个JSON缓存和从URL获取JSON对象：

let cache = Cache<JSON>("movies")
let URL = NSURL(string: "http://haneke.io/movies.json")
cache.fetch(URL: URL).onSuccess { JSON in
    // Do something with JSON
}

特性

• Generic cache with out-of-the-box support for UIImage, NSData, JSON and String
• First-level memory cache using NSCache
• Second-level LRU disk cache using the file system
• Asynchronous fetching of original values from network or disk
• All disk access is performed in background
• Thread-safe
• Automatic cache eviction on memory warnings or disk capacity reached
• Comprehensive unit tests
• Extensible by defining custom formats, supporting additional types or implementing custom fetchers
