YYCache

License MIT  Carthage compatible  CocoaPods  CocoaPods  Support  Build Status

High performance cache framework for iOS.
(It's a component of YYKit)

Performance

Memory cache benchmark result

Disk benchmark result

You may download 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.
