SwiftCache is a pure swift cache framework inspired by YYCache

Requirements

iOS 8.0+
Xcode 8.0
Swift 3.0

Installation

Carthage

Create a Cartfile that lists the framework and run carthage update.

Follow the instructions to add$(SRCROOT)/Carthage/Build/iOS/SCache.framework to an iOS project.

github "tbxark/SwiftCache"

Usage example

UIImage

let imageCache = SwiftCache<String, UIImage>(name: "Image")
imageCache?.setValue(UIImage(named: "test"), withkey: "test")
let img = imageCache?.valueForKey("test")

Struct

struct CacheStruct: Cacheable {

    let name: String
    let value: String

    static func build(_ data: Data) -> CacheStruct? {
        guard let obj = try? JSONSerialization.jsonObject(with: data, options: .allowFragments),
              let dict = obj as? [String: String],
              let n = dict["name"],
              let v = dict["value"]  else { return nil }
        return CacheStruct(name: n, value: v)
    }
    func mapToData() -> Data? {
        let dict = ["name": name, "value": value]
        return try? JSONSerialization.data(withJSONObject: dict, options: [])
    }
}

let structCache = SwiftCache<Int, CacheStruct>(name: "Struct")
let a = CacheStruct(name: "A", value: "A")
structCache?.setValue(a, withkey: 1)
if let aCache = structCache?.valueForKey(1) {
    print(aCache)
}

Description

在 OC里面 YYCache 算是最出色的一个缓存框架

我在研究 YYCache 的代码的时候就顺便用 Swift 仿写了一遍, 毕竟比起看代码, 写代码更能加深理解.

写得时候也充分的利用的 Swift语言的优势, 加上了泛型和 Any 类型的支持(因为YYCache是 OC 写的所以只能缓存 class 类型).

Thanks
