EBDownloadCaching is a framework that includes several classes that implement performant HTTP downloading and caching; the various components are described below.
EBDownload is a class encapsulating a single-use download from a HTTP/HTTPS URL. EBDownload offers performant downloading by using libcurl under the hood, and provides a simple block-based interface to supply the resulting download data and status. Clients can use EBDownload directly to easily download the contents of URLs, or alternatively use the caching classes described below to add a layer of caching and avoid downloading data unnecessarily.
An EBDownload instance can be used safely from multiple threads simultaneously.
EBDownloadCache provides caching functionality for the data retrieved by an EBDownload, supporting two levels of caching: in-memory caching using NSCache, and on-disk caching using EBDiskCache.
EBImageDownloadCache is a simple subclass of EBDownloadCache that stores CGImages in its in-memory cache, instead of raw data.
