SELoadImageASync - Image Caching was never that easy!

What is SELoadImageASync?

SELoadImageASync is a simple handy Obj-C method used to load image from URL into a UIImageView ASynchronously and cache it on device forever, all that with just one line of code!

It has more features including:

1. Loads photos from URL asynchronously.
2. Automatically detects whether image is already cached.
3. Shows an UIActivityIndicatorView until image is loaded.
4. User may select a default photo that is displayed until image is loaded.
5. Handles multiple function calls for downloading same file many times (i.e. when used under UITableView).
6. Built to deal with many-to-many relationship between UIImageViews and Images that are downloaded.

How to use it in your iOS applications

1. Simply add both SELoadImageASync.h and SELoadImageASync.m into your project.

2. Add #import "SELoadImageASync.h".
