SDWebImage is a simple image library for iOS which provides caching and an easy way to load remote images asynchronously into UIImageViews.

This library provides a category for UIImageVIew with support for remote images coming from the web.

It provides:

  • An UIImageView category adding web image and cache management to the Cocoa Touch framework
  • An asynchronous image downloader
  • An asynchronous memory + disk image caching with automatic cache expiration handling
  • A guarantee that the same URL won't be downloaded several times
  • A guarantee that bogus URLs won't be retried again and again
  • Performance

More info can be found on the github page.
