High performance cache framework for iOS.<br/>
|
||
|
(It's a component of [YYKit](https://github.com/ibireme/YYKit))
|
||
|
|
||
|
Performance
|

|

|
||
|
You may [download](http://www.sqlite.org/download.html) and compile the latest version of sqlite and ignore the libsqlite3.dylib in iOS system to get higher performance.
|
||
|
|
||
|
See `Benchmark/CacheBenchmark.xcodeproj` for more benchmark case.

Features
|
||
|
==============
|
||
|
- **LRU**: Objects can be evicted with least-recently-used algorithm.
|
||
|
- **Limitation**: Cache limitation can be controlled with count, cost, age and free space.
|
||
|
- **Compatibility**: The API is similar to `NSCache`, all methods are thread-safe.
|
||
|
- **Memory Cache**
|
||
|
- **Release Control**: Objects can be released synchronously/asynchronously on main thread or background thread.
|
||
|
- **Automatically Clear**: It can be configured to automatically evict objects when receive memory warning or app enter background.
|
||
|
- **Disk Cache**
|
||
|
- **Customization**: It supports custom archive and unarchive method to store object which does not adopt NSCoding.
|
||
|
- **Storage Type Control**: It can automatically decide the storage type (sqlite / file) for each object to get
|
||
|
better performance.

|
==============
|
||
|
高性能 iOS 缓存框架。<br/>

性能
|
||
|
==============
|
||
|
|
||
|
iPhone 6 上,内存缓存每秒响应次数 (越高越好):

)
|
||
|
|
||
|
推荐到 SQLite 官网[下载](http://www.sqlite.org/download.html)和编译最新的 SQLite,以替换 iOS 自带的 libsqlite3.dylib,以获得最高 1.5~3 倍的性能提升。

特性
|
||
|
==============
|
||
|
- **LRU**: 缓存支持 LRU (least-recently-used) 淘汰算法。
|
||
|
- **缓存控制**: 支持多种缓存控制方法:总数量、总大小、存活时间、空闲空间。
|
||
|
- **兼容性**: API 基本和 `NSCache` 保持一致, 所有方法都是线程安全的。
|
||
|
- **内存缓存**
|
||
|
- **对象释放控制**: 对象的释放(release) 可以配置为同步或异步进行,可以配置在主线程或后台线程进行。
|
||
|
- **自动清空**: 当收到内存警告或 App 进入后台时,缓存可以配置为自动清空。
|
||
|
- **磁盘缓存**
|
||
|
- **可定制性**: 磁盘缓存支持自定义的归档解档方法,以支持那些没有实现 NSCoding 协议的对象。
|
||
|
- **存储类型控制**: 磁盘缓存支持对每个对象的存储类型 (SQLite/文件) 进行自动或手动控制,以获得更高的存取性能。
