Haneke/HanekeSwift
HanekeSwift
HanekeSwift is a generic caching library for iOS and a specialized image caching framework. It provides a multi-level system that stores arbitrary data types in memory and on persistent disk storage to reduce network requests.
The project features a specialized image handler that manages asynchronous loading, resizing, and disk storage for user interface components. It includes a background retrieval system that fetches remote content and automatically populates local caches.
The library covers key-value data storage with sequential fallbacks, where it checks memory, then disk, and finally remote sources. It implements automated capacity management through memory eviction policies and handles data decompression and transformations off the main thread.
Features
- Local Data Caches - Provides a multi-level caching system that stores lightweight data and serialized objects on the device.
- Hybrid Memory-Disk Caches - Implements a multi-level caching system combining fast in-memory storage with persistent disk storage for arbitrary Swift types.
- Asynchronous Content Retrievers - Provides a background retrieval system to fetch remote content and populate local caches asynchronously.
- Asynchronous Data Fetching - Provides a mechanism to retrieve data from remote or disk sources on secondary threads to maintain UI responsiveness.
- Generic Object Storage - Saves any object or data structure that can be converted to and from a data representation.
- iOS Persistent Image Caches - Implements disk-based caching specifically for iOS to ensure fluid scrolling in list-based views.
- Generic Data Caches - Provides a storage mechanism synchronizing memory and disk persistence for generic data on iOS.
- Persistent Key-Value Caches - Saves and retrieves generic data types using unique keys to balance memory and disk usage.
- Remote Data Fetching - Implements asynchronous retrieval of data from external network sources when local cache misses occur.
- Image Caching Frameworks - Offers a comprehensive framework for asynchronous image loading, resizing, and multi-tier caching on iOS.
- Sequential Fallbacks - Checks for data in memory first, then disk, and finally remote sources in a predefined sequence.
- Cache Eviction Policies - Automatically evicts old or unused data when system memory warnings occur or storage limits are reached.
- UI Component Integrations - Retrieves and resizes cached images specifically for user interface components and cell reuse.
- Remote Data Retrieval - Retrieves values from network or custom sources only when they are missing from the local cache.
- iOS Memory Optimization - Automatically evicts unused cached data during system memory warnings to improve memory efficiency on iOS.
- LRU Cache Eviction - Automatically removes the least recently used items from the cache when memory limits are reached.
- Off-Main-Thread Processing - Processes image decompression and resizing off the main thread to maintain a fluid user interface.
- Asynchronous Data Processing - Handles data decompression and transformations on background workers to maintain a responsive user interface.
- Asynchronous Image Decoding - Performs image decompression and resizing on background threads to prevent main thread blocking during scrolling.
- Scrolling List Optimizations - Populates views and buttons with cached content using methods optimized for fluid scrolling lists.
- Cache - Caches images and data with a lightweight API.
- Caching Utilities - Lightweight generic cache for iOS.
- Image Processing - Lightweight Swift caching framework with image support.
