利用YYCache和AFN实现网络数据缓存

背景

网络比较差的情况为了提高用户体验需要先显示旧的数据，拿到新数据在更新
对于短时间内变化不大的数据，用户重复获取数据不仅浪费浏览也增大服务器的压力

项目类

主要分为缓存类HZNetWorkCache、配置类HZNetworkConfig、网络请求类HZNetworkManager

HZNetWorkCache

缓存类比较简单，主要实现数据的存储，基于YYCache
将网络请求的连接和提交的参数拼接作为key
将网络请求后台返回的数据作为value
设置缓存时间，每次读取缓存都先校验缓存时间的有效性
1）将网络请求的连接和提交的参数、"_HZNetworkTimeOut"（常量，可随意）拼接作为key
2）将缓存时间作为value

HZNetworkConfig

该类主要用于网络请求配置

baseURL（NSString）网络请求基链
requestSerializer（AFHTTPRequestSerializer）请求的一些配置（默认不变的信息）
responseSerializer（AFHTTPResponseSerializer）对返回的数据进行序列化，默认使用 AFJSONResponseSerializer
builtinHeaders （NSMutableDictionary）请求的头部通用配置
builtinBodys（NSMutableDictionary）请求体通用配置
timeoutInterval（NSTimeInterval）请求超时时间设置，默认10秒
resultCacheDuration（NSInteger）设置缓存时间，默认7246060秒（724小时）。如果 <= 0，表示不启用缓存。单位为秒，表示对于一个请求的结果缓存多长时间
requestCachePolicy（HZRequestCachePolicy）缓存策略, 默认是HZRequestCacheOrLoadToCache
(^ resposeHandle)(NSURLSessionTask *dataTask, id responseObject) 对请求返回的数据做统一的处理，比如token失效、重新登录等等操作。

缓存策略

typedef NS_ENUM(NSUInteger, HZRequestCachePolicy) {
    /** HZRequestCacheOrLoadToCache, HZRequestCacheAndLoadToCache, HZRequestLoadToCache这三种方式如果网络请求失败且有缓存数据则直接返回缓存数据（不管缓存数据是否有效），如果不存在缓存则直接返回failured */
    HZRequestCacheOrLoadToCache,//如果缓存有效则直接返回缓存，不再load。缓存失效则load返回，且缓存数据，用于同一个网络请求在一定时间内不多次发起网络请求
    HZRequestCacheDontLoad,//如果缓存有效则直接返回缓存，缓存失效则返回nil，不再load
    HZRequestCacheAndLoadToCache,//如果缓存有效则直接返回缓存，并且load且缓存数据。缓存失效则load返回，且缓存数据
    HZRequestLoadToCache,//直接load并返回数据，且缓存数据，如果load失败则读取缓存数据
    HZRequestLoadDontCache,//直接load并返回数据，不缓存数据，如果load失败则直接抛出Error
};
